New Cybersecurity Testing Lab Opens in Cheltenham

A new cyber security laboratory has recently opened close to Cylera's UK offices in Cheltenham, and near GCHQ, the UK’s intelligence agency. The 5,200 sq ft lab plans to test IIoT, IoT, OT, ICS, SCADA and embedded devices which now make up a surprising percentage of connected endpoints. These devices are largely regarded by the profession as being inherently insecure and rarely patched against security vulnerabilities by their owners. The greatest problem however is that vulnerabilities are usually unknown by either owners or manufacturers.

The lab’s prime goal is to test vulnerability of vehicles, private jets, and aircraft engines. With this, the laboratory aims on strengthening industrial systems against malicious cyber activities.

This was the subject of my radio interview with BBC Radio Gloucestershire this morning. Listen to the 7 minute discussion below.

FDA Implements New Rules

The March 29th FDA rule changes for the acceptance of new medical devices is a long awaited and major step in the right direction towards improving the security of medical devices. Finally, after more than a decade of pressure from cybersecurity leaders and healthcare providers, manufacturers of medical devices are to be held to a much higher standard of security design, manufacture, and support, of the devices they produce and sell, or lease to providers.

This includes the broader sharing of security information including a Software Bill of Materials (SBoM) of the components within each device and the testing and disclosure of any known vulnerabilities. No longer can manufacturers simply produce devices and move onto the next innovation. They now have a legal duty of care to support those devices they produce from now on. This change goes into effect on Oct 1st and sets a new standard of acceptance by the FDA. Devices submitted that do not adequately demonstrate adherence to the new requirements will likely be refused acceptance and will not be cleared for use.

The fact that the rules were published on the last Friday in March on the very last day that Congress stipulated in its Consolidated Appropriations Act of 2023, (signed into law on Dec. 29), shows just what a herculean task these rules must have been for the FDA and the very small team tasked with the security of medical devices. The size of that team looks to be expanded over coming months, but the government is not renowned for moving quickly so these rules were likely framed by the existing small team headed by Dr. Suzanne Swartz in the Office of Strategic Partnerships & Technology Innovation at CDRH. This is a group with a long history of dialog with manufacturers and healthcare cybersecurity leaders, with in-depth knowledge of both medical and cybersecurity concerns.

"I would expect there to be many more changes to the rules published by FDA over the next year or two as requirements are refined and clarified more definitively,” claimed Richard Staynings, Chief Security Strategist with Cylera and Adjunct Professor of Cybersecurity and Health Informatics at the University of Denver, who has been following these changes closely.

“The manufacturing industry has a long history of claiming not to understand many years of voluntary FDA Pre-Market Guidance, and so avoided making changes. I suspect that some will try the same approach now that the rules are mandatory,” suggested Staynings. “This reluctant approach to change, combined with I suspect, some real ambiguities despite the hurried best efforts of the FDA, will manifest itself in minor changes becoming necessary to the rules.”

Indeed, the FDA final guidance recently published, only impacts new devices being submitted for approval. The new rules fail to address those medical devices that are already approved and in use by medical providers. With a lifespan between 8 and 20 years, legacy medical devices will be a feature of hospitals and other providers for many years to come. They number in the millions, and many are considered a security risk in today’s already vulnerable connected digital healthcare networks.

Hospitals have proven time and time again that amortization schedules on medical and IT equipment are not to be overwritten by gaping security vulnerabilities unless severe patient safety risks can be demonstrated. This means that providers will need to continue to employ compensating IoMT security controls and widescale use of micro-segmentation of at-risk medical devices using network access control (NAC) and software defined networking (SDN), capabilities they already own though may not realize they do.

“I would suspect that in 2024, we will see additional FDA rules that provide increased security guidance on legacy devices and introduce new requirements for manufacturers.” Claimed Staynings. “At the very least this will need to include publication of SBoMs for legacy devices and vulnerability disclosures. It ideally should also require manufacturers to test and make security patches available for legacy devices, though mandating this retroactively on already approved devices may be difficult. Furthermore, the legal mandate behind rule changes, may need some level of amendment to the Protecting and Transforming Cyber Health Care (PATCH) Act of 2022.”

The Importance of an SBoM

Despite being a vital step in the security of medical devices, publication of SBoMs is not a panacea, nor are SBoMs foolproof, they merely provide security teams with a better understanding of vulnerabilities when a component in a device is found to be vulnerable elsewhere. Given the widespread re-use of hardware and software components, and software libraries by developers and systems manufacturers today, this will be useful to some providers. Smaller providers, and those with less mature security teams will be unlikely to benefit from published SBoMs since they lack the depth and breadth of capabilities to do much about known vulnerabilities already. Small and ill-equipped hospital security teams are slowly going away however as health systems merge or take advantage of outsourced security specialists. “Knowing that a number of security vulnerabilities exist, and being able to do something about those vulnerabilities are two separate things,” claimed Staynings.

The New Manufacturer Paradigm

Over the next six months manufacturers of ‘cyber’ connected medical devices will need to evaluate the security of the devices they have in development to consider each’s overall security protections, to test each device for security vulnerabilities and to build and maintain improved security documentation including an SBOM and develop improved capabilities to support new requirements around security vulnerabilities disclosure. “This should not be ‘news’ to any of them given the passage of the PATCH act on March 15th 2022, over a year ago, or years of FDA guidance preceding the act. In fact, all manufacturers have seen the writing on the wall for quite some time”, claimed Staynings. “Manufacturers should examine the new FDA rules very closely and seek immediate clarification if they don’t understand fully, so that their devices are not refused acceptance come October.”

A Welcome Reset

“The passage of the new rules is a welcome reset for medical device security,” claimed Staynings during an interview with SCMedia. This has been one of several open backdoors to securing healthcare for quite some time, and with the growth in medical devices hitting 18% per annum in 2022 this is both a growing concern and gaping risk, that is now finally after much effort, being addressed by new FDA rules.

New FDA Rules Go Into Effect

Yesterday the FDA gave notice that as of Oct 1st it will “refuse to accept” medical devices and related systems unless they meet its new cybersecurity requirements which went into effect March 29th, 2023. These requirements are embodied in new FDA final guidance on its Refuse to Accept (RTA) policy relating to cybersecurity in medical devices, specifically for “Cyber Devices” as defined in the newly-amended FD&C Act (Section 524B).

These powers come out of the Protecting and Transforming Cyber Health Care (PATCH) Act of 2022 and the provisions which were funded under the Consolidated Appropriations Act of 2023 signed into law on Dec. 29. Given the passage of both acts last year, and growing demands for improved medical device cybersecurity going back at least a decade, this should come as no surprise to manufacturers.

Indeed, pre-market FDA security guidance prior to the new law has stipulated increased security requirements, though many manufacturers have not yet implemented this guidance. Under the new powers, improvements in the cybersecurity and ongoing support of medical devices is now mandatory.

This means that if you’re a company building a medical “cyber device”, it is now a requirement that you build your device to be secure by design, develop strategies to monitor and maintain the security of that device post-market and for the life of the device, generate and maintain a software bill of materials, and generate the requisite documentation proving you’ve done so as part of your FDA regulatory submission.

A New Era in Medical Device Security

The days of build, sell, and forget, are now over. While some manufacturers were better than others about cybersecurity and ongoing patch support, others were plainly borderline negligent. The refusal to patch known highly vulnerable medical devices resulted in the FDA issuing its first ever medical device recall in 2017 following the very public disclosure of critical security vulnerabilities from the hacking of a St Jude Medical cardiac defibrillator. St Jude Medical had a long history of refusing to patch its insecure medical devices, and shortly after the disclosure, the company was sold to Abbott Labs reportedly at a big discount.

Submissions to FDA need to include a software bill of materials, which must contain all commercial, open-source, and off-the-shelf software components, while complying with other FDA requirements “to demonstrate reasonable assurance that the device and related systems are cybersecure.” This allows healthcare provider security teams to immediately understand and react to their exposures when CVEs are published for individual software components rather than wait for medical device manufacturers to assess and publish their own vulnerability disclosures.

Device manufacturers will need to submit plans to monitor, identify and address in a "reasonable timeframe" any determined post-market cybersecurity vulnerabilities and exploits, including coordinated vulnerability disclosures and plans. “While the language here is vague and not specific, it’s a big improvement over current arbitrary disclosure practices” claimed Timur Ozekcin, CEO of Cylera.

Developers must now design and maintain procedures able to show, with reasonable assurance, “that the device and related systems are cybersecure” and create post-market updates and patches to the device and connected systems that address “on a reasonably justified regular cycle, known vulnerabilities,” according to the guidance.

If discovered out-of-cycle, the manufacturer must also make public “critical vulnerabilities that could cause uncontrolled risks,” as soon as possible. “This appears to be weaker requirements than the originally proposed 30-day patch availability requirement, as is common for other software when critical vulnerabilities are discovered, but it’s a lot better than the current situation,” added Ozekcin.

“These changes mark a much-needed improvement to the security of connected medical devices, but they don’t cover the millions of legacy devices currently in use in our hospitals and clinics. Unless the FDA introduces rules to address these legacy devices then it may take many years before the security of the healthcare industry is significantly impacted,” claimed Richard Staynings, Chief Security Strategist with Cylera. “Medical devices have an expected lifespan of between 8 and 20 years in some cases, so the security of these systems will more than likely be an issue till 2043 and that’s too long,” he added.

While not all connected medical devices will develop security vulnerabilities, many will over the course of their lifetime and amortization schedule. What is needed is a way to better identify medical and other healthcare IoT connected devices, understand their risks and accurately profile devices so that software defined networking (SDN) tools like network access control (NAC) can be used to segment and isolate potentially at-risk systems. AI based tools like Cylera MedCommand now automate this entire process leading to seamless orchestration of security policy across the healthcare network.

2023 Predictions

As 2022 draws to a close, what can we learn from a year marked by Russia's invasion of Ukraine, crippling cyber and kinetic attacks against critical infrastructure not just in Ukraine but across the world, and a continued rise in cyber attacks and ransomware globally? A year in which Russia, China and Iran have all become victims of cyber attacks, perhaps reaping the seeds sown by each of them in the past. And a year which saw the costs of cyber-crime move well above its $6 trillion 2021 levels even though the year is not over yet and the full costs counted.

Can and should we extrapolate trends identified over the past year and claim that these trends will continue in their upward path, or is the cyber threat landscape more complicated than we generally assume it to be.

With both Russia and China, the two greatest perpetrators of cyber-crime, increasingly isolated from the rest of the world, and with growing domestic dissent in China, Iran and Russia, are geopolitical moves against autocrats likely to change the world's three most egregious offensive cyber actors?

2022 - A Year in Reflection

In 2022 we saw a massive collapse and re-alignment of organized crime groups following the Russian invasion of Ukraine in February. Prior to the war, these groups consisting of perpetrators located right across the Commonwealth of Independent States (CIS) were united predominantly by their use of the Russian language. During the invasion, Ukrainian and other non-Russian members pulled out of many of these Russian led groups, and some even turned on their former gangs exposing their inner most secrets and the identities of leaders. This break up caused a dip in attacks in March and April and was further hampered by many global ISPs withdrawing from business in Russia. The result was a dramatic reduction in the Internet bandwidth into Russia for many of these groups to use.

Since the onset of war, many of the leaders of these crime gangs, who operate under the eye of the Russian Mafia, who in turn operate with impunity under the oligarchs and ultimately the Kremlin, have quit the profession, scared that Russia will collapse along with Putin’s protective umbrella. Many are worried that they might be identified, caught, and prosecuted. Most have taken their millions in ill-gotten gains and ran, going deep underground. This has left a power vacuum in Russian organized crime syndicates where young, fearless, and ruthless new leaders have taken over. This has led to reckless attacks including the targeting of healthcare providers. A ‘live today die tomorrow’, ‘get rich quick’ mentality now persists as many of those involved are scared of being conscripted by the Russian Army and being sent off to die in Ukraine. Some of these cybercriminals have even acted upon their disdain for the Putin dictatorship, by launching cyberattacks against the Kremlin itself, a very risky proposition indeed.

At the same time, the affiliates of many of these ransomware-as-a-service (RaaS) groups have gone rogue, distancing themselves from Russia and from RaaS providers. With re-alignment complete, the gloves have been taken off and affiliates are hunting freely by themselves and are prepared to take much higher risks than previously allowed. Again, this includes the targeting of healthcare and other national critical infrastructure industries.

Unsurprisingly this has piqued the attention of the FBI, Homeland Security, and other law enforcement groups. Its also one of the main reasons behind the recent FBI warning about one of these groups in particular, Daixin. This group is widely accredited with the September / October ransomware attack against Common Spirit Health, the second largest US healthcare provider. The attack impacted hundreds of provider facilities across most US states, denying timely care to millions of US citizens.

If we thought that the threat landscape was bad in 2021, 2022 has turned into the wild west with rogue gun-slingers on every corner and dead bodies mounting up on every street! For an easy target like healthcare, prospects don’t look good. With its collection of out-of-date weapons, no money to buy new tools, and very small ill-equipped teams, it stands almost no chance defending against an increasingly out-of-control and rabid gang of adversaries.

But the Russian and other CIS gangs aren’t the only things that healthcare needs to be concerned about. Increased offensive activity against providers has been seen coming from both China and Iran. With Iran recently appearing to side with Putinist forces. With threats of further sanctions from Europe and the USA, and rising internal revolt against the theocratic dictatorship that runs the country, Iranian forces are on the offensive. So too is China, and now that Xi has unchecked power over the CCP and the country for life, it is likely that China’s massive PLA cyber army will launch new offensives against western critical infrastructure providers, as China increasingly uses cyber weaponry against its perceived enemies.

Any healthcare CEOs that still have their heads buried in the sand, thinking that a cyberattack is unlikely to impact their hospitals, had better find a deep cave in which to hide, because the noise of collapse in 2023 will be omnipresent.

"We are seeing 2 to 3 ransomware attacks against US healthcare providers each and every day at the moment,” claimed Richard Staynings, Cylera's Chief Security Strategist in a recent interview. “That is not about to go down any time soon, so long as hospital boards and CEOs keep paying the ransoms. Instead of paying the criminals holding them to extortion, they need to invest properly in security and IT which is totally underfunded. This is especially so if you analyze the risks or compare the healthcare industry with other industries such as financial services. It’s somewhat analogous to crime victims paying protection money to the mafia, while refusing the properly fund the police or the FBI" he added.

"I wish that I had a more positive prediction for 2023 but that would be putting lipstick on the pig" claimed Staynings.

Are we doing a better job today of defending against attacks than we were a few years ago? Many cybersecurity leaders would say that we are but that the goal posts have moved. Some health systems have prioritized cybersecurity, but most have a long way to go. And that comes back to governance, leadership, and the prioritization of cybersecurity. Most cybersecurity leaders would agree that it's not where it needs to be right now.

Nor unfortunately is the level of cyber protection being provided by Homeland Security, the FBI and others. Governments are never quick to act but plainly, expecting small critical access facilities to protect themselves against highly sophisticated nation-state actors and organized crime syndicates is ridiculous.

As Staynings puts it, "it’s not even analogous to David and Goliath. It’s more akin to a lone Maasai warrior armed with a spear going up against an entire regiment armed with machine guns. The Maasai warrior stands almost no change at all!"

The rising threat of Offensive AI

Various forms of artificial intelligence (AI) look set to transform medicine and the delivery of healthcare services as more and more potential uses are recognized, while adoption rates for AI continue to climb.

Machine Learning (ML) has revolutionized clinical decision support over the past decade, as has AI enhancement of radiological images allowing the use of safer low-dose radiation scans. But AI no matter in which form, requires massive amounts of data for modelling, training, and for mining. While much of that data is de-identified, some cannot be, as training can sometimes require the aggregation of each patient's set of medical tests and records, thus the patient must be known to the AI, in order for it to learn and model correctly.

But healthcare data is valuable. Its valuable to hackers who can ransom it back to data custodians or sell that PII and PHI data on the darknet. Its valuable to nation states such as China for its own data modelling and AI training. Furthermore, medical data is highly regulated and so is subject to fines, punitive damages, restitution and corrective action plans when breached.

AI models are highly valuable and are now the modern day equivalent of the 1960s' 'race to the moon' between the US and USSR. Only the competitors today are the USA and the PRC. Consequently, China has been very aggressive in 'acquiring' whatever research it can to jump-start or enhance its own AI development programs. This has included insider theft by visiting professors and foreign students at western universities, and targeted cyberattacks from the outside. China's five year plan is to surpass the west in its AI capabilities - not just for medical applications but also for military-defence. So for both countries and others, AI is a strategic imperative. It is perhaps ironic that AI is now being used to bypass network defenses to steal .... AI training data among other things as will be explained shortly.

AI in Cybercrime

AI may become the future weapon of choice for cybercriminals. Its unique abilities to mutate as it learns about its environment and masquerade as a valid user and legitimate network traffic allows malware to go undetected across the network bypassing all of our existing cyber defensive tools. Even the best NIDS, AMP and XDR tools are rendered impotent by AI's stealthiness.

AI can be particularly adept when used in phishing attempts. AI understands context and can insert itself into existing email threads. By employing natural language processing to use similar language and writing style to users in a thread, it can trick other users into opening malware-laden attachments or to click on malicious links. Unless an organization has sandboxing in place for attachments and links to external websites, then AI based phishing will have a high margin of success. But things don't stop there.

Offensive AI has been used to weaponize existing malware Trojans. This includes the Emotet banking Trojan which was recently AI enabled. It can self-propagate to spread laterally across a network, and contains a password list to brute force its way into systems as it goes. Its highly extensible framework can be used for new modules for even more nefarious purposes including ransomware and other availability attacks. Regulation requires providers to protect the confidentiality, integrity and availability of protected health information and systems, but in healthcare availability is everything. When health IT and IoT systems go down so does a provider's ability to render care to patients in today's highly digital health system. This digital industry is now dependent upon its IT and IoT systems.

Offensive AI can also be used to execute integrity based attacks against healthcare. This is where the danger really lies. AI blends into the background and uses APT techniques to learn the dominant communication channels seamlessly merging in with routine activity to disguise itself amid the noise. AI can change medical records, altering diagnoses, changing blood types, or removing patient allergies, all without raising alarm.

It's one thing for physicians not to have access to medical records, but to have access to medical records which have had their data maliciously altered is another. It's also far more dangerous if the wrong treatment is then prescribed based upon that bad data. This becomes a major clinical risk and patient safety issue. It also denudes trust in the HIT and HIoT systems that clinicians rely upon, and may eventually lead to physicians questioning the data in front of them or having to second guess that information.

• Can I trust a medical record?
• Can I trust a medical device?

It also raises some major questions around medical liability.

A research study in 2019 at Ben-Gurion University of the Negev was able to compromise the integrity of a radiological image by inserting fake nodules into an image between the CT scanner and the PACS systems or by removing real nodules from a CT image by using Deep Learning (DL). The research wasn't purely theoretical either, but used a blind study to prove its thesis that radiologists could be fooled by AI altered images.

The study was able to trick three skilled radiologists into misdiagnosing conditions nearly every time using real CT lung scans, 70 of which were altered by their malware. In the case of scans with fabricated cancerous nodules, the radiologists diagnosed cancer 99 percent of the time. In cases where the malware removed real cancerous nodules from scans, the radiologists said those patients were healthy 94 percent of the time.

The implication of such a powerful tool if used maliciously is obviously huge, resulting in cancers remaining undiagnosed or patients being needlessly misled and perhaps operated on.

In the run up to the 2016 presidential election a hoarse sounding Hillary Clinton decided to share a recent CT image with the media to prove that she was suffering from pneumonia rather than long term health concerns such as cancer. Had her chest image been altered to indicate cancer its likely that she would have been forced to withdraw from the election. Either way, a American Presidential election could have been compromised and AI potentially used to alter its outcome. AI could thus become a powerful weapon for nefarious nation states to undermine democracy and wishing to destabilize a country. The same tools could also be used by radical domestic groups one day to change the outcome of an election.

Deepfakes

The rising capabilities and use of Deepfakes for Business Email Compromise (BEC) whether using audio or video, will render humans unable to differentiate between true and false, real and fake, legitimate and illegitimate. "Was that really the CEO I just had an interactive phone conversation with telling me to wire money overseas?"

But Deepfakes could be very dangerous from a national security perspective also, domestically and internationally. "Did the President really say that on TV?"

Compared to Ronald Reagan's 1984 hot mike gaffe about bombing Russia, a deepfake might be much more convincing and concerning as the majority of people would likely believe what they saw and heard. After all, much of the US population believe what they read on social media or on news sites that constantly fail fact-checking. But the US population is not alone in being easily led as we have seen in Russia, where most of the Russian population has been found to believe the state propaganda presented on TV about Putin's war against Nazis in Ukraine.

Cognitively, we are not prepared for deepfakes and are not preconditioned to critically evaluate what we see and hear in the same way that we may challenge a photo in a magazine that may have been photoshopped. AI obviously has massive and as-yet untapped PhyOps (psychological operations) capabilities for the CIA, FSB, MSS, and other clandestine agencies.

As these and other 'Offensive AI' tools develop and become more widespread, it is likely that cybersecurity practitioners will need to pivot towards greater use of 'Defensive AI' tools. Tools that can recognize an AI based attack and move quickly (far quicker than a human) to block such an attack. Indeed, it is likely that future AI-powered assaults will far outpace human response teams and that almost nano-second responses will be needed to prevent the almost pandemic spread of malware across the network.

According to Forrester's "Using AI for Evil' report, "Mainstream AI-powered hacking is just a matter of time."

RSNA 2022

Cybercrime against healthcare institutions has exploded in recent years. In 2021, more than 1 in 3 healthcare organizations reported being hit by ransomware.

The situation has been considerably worsened by the pandemic, which produced a triple threat for healthcare systems: a rapid expansion of internet-connected technologies and services causing an expanded attack surface, an increase in many types of cyberattacks, and fewer available resources to defend against cyberattacks.

Cybersecurity has become an important part of healthcare, and every radiology practice can easily become victim of a targeted cyber-attack. This was the subject of one of the opening education lectures of the recent RSNA (the Radiological Society of North America) conference in Chicago presented by Professor Benoit Desjardins, MD at Penn Medicine,  Associate Professor Shandon Wu, at University of Pittsburgh, and the author.

AI is now extensively used by both attackers (“Offensive AI”) and defenders (“Defensive AI”).  This four part lecture explored three forms of interaction between AI and cybersecurity that affect healthcare:

(1) Offensive AI: how cybercriminals are weaponizing artificial intelligence to improve their attacks against medical institutions, including how cyber-criminals are using AI to improve success of different types of attacks, such as phishing, scanning, and intrusions of medical centers.

(2) Defensive AI: how cyber-defense teams at medical centers are using artificial intelligence to supplement the limited capabilities of humans to detect and defend against cyberattacks, especially now that many of those cyberattacks are controlled by artificial intelligence.

(3) AI Model Safety: how cyber-threats can disrupt the integrity of medical images, and how this affects diagnosis by AI and humans, including an overview of the multiple ways in which data can be modified to fool AI algorithms.

(4) A panel discussion of the practical implications of AI for radiology practices.

AI is incredibly powerful and in a radiological imaging environment can mean the difference between early and timely diagnosis of cancers and other potentially life threatening conditions, or a medical condition not being discovered until it's too late. But Radiologists should be aware that AI models can be poisoned and corrupted, or used for nefarious purposes. If AI modelling and training is conducted safely and securely however, the benefits appear to far outweigh the risks.

ISfTeH

Richard Staynings with Michele Griffith MD, President of ISfTeH.

The 'International Society for Telemedicine & eHealth' held its annual conference in San Jose, CA today and the author was proud to be invited to speak on the subject of 'cybersecurity as an enabler of new remote medical services'. 

 

Remote patient services whether telehealth consults with a primary care physician, post operative recovery from home to free up needed hospital beds, or the right of patients to die in their own home (embodied in law in many jurisdictions now), requires a different approach to patient data protection, privacy and security. Indeed, many of the new services envisaged as part of improvements to patient care for the future, will require careful examination to ensure that these do not expose provider medical networks to undue risks. Personalized medicine looks set to transform patient well-being and intervention outcomes but if providers are to store and process patients' DNA then they need to do a much better job of protecting that information than they do protecting current personal health information. 

 

Regulation across multiple jurisdictions requires that the confidentiality (privacy) of electronic patient information (ePHI) be protected, yet from a risk perspective loss of confidentiality although still important, is minor compared to the loss of health data integrity (the changing of a medical record) or the loss of availability (patients unable to receive an X-ray or CT scan while in the Emergency Room). 

 

With multiple hospitals being attacked with ransomware every week today, the risks for providers are obviously great. Although the costs of loss (lost revenue) can be massive, (Scripps Health is reported to have lost $112.7 million in revenue following its ransomware attack in 2021), the impact to patients for protracted downtime caused by a cyber attack can be life threatening, impacting patient safety, morbidity and even mortality, as we have seen from some prior ransomware attacks. Cyber-criminal activity by extortionists is literally killing people. Cyber attacks against the 'availability' of health services can be devastating to patients in need of radiotherapy or chemotherapy when those services are denied them. The same is true for those in need of Emergency Care or those giving birth when health IT and IoT are unavailable and being held to ransom.

 

The conference heard that it is important to balance 'confidentiality', 'integrity' and 'availability' of health information that together form what is known as the CIA triad. It also heard that a more risk-based-approach is required if providers are to get in front of managing the proliferation of new AI and ML based technologies, clinical applications and medical devices.

A full copy of the author's deck can be found here.

 

Attendees, speakers and panelists came from all over the world and were drawn from many different medical disciplines and specialties.  This was the first international conference of the ISfTeH since COVID-19 locked down many countries and prevented international travel.

Are Your Vendors Introducing Risk?

Cyber risks in healthcare are not just confined to data centers, to nursing stations, or to the PHI data that flows back and forth between health insurers, HIEs, government agencies, and patients. The risk matrix is much bigger than that.

It includes thousands of suppliers, vendors, and partners that stretch across the globe. Everything from business process and IT outsourcers in India, to complex manufacturing supply chains for medical equipment in China, Brazil, Germany, Australia, and the UK can all fall under the umbrella of cyber risk susceptible access points.

Alarmingly, this risk matrix in healthcare also encompasses the company that provides hot meals to your patients, and food and coffee for the hospital cafeterias, as well as the pharmaceutical companies conducting clinical trials, and biomedical engineering companies providing prosthetics, or an implantable medical device (IMD) that leaves the hospital with a surviving patient. Anyone who has physical access to your sites, network access to your IT, or who processes your data, regardless if they ever see one of your patients or not, can introduce risk to your business.

 

Dismaying Numbers in The Data

A vendor vulnerability index research report released by Bomgar showed that breaches occurring from third parties account for two-thirds of the total number of reported cyber breaches. The study found that only 46% of US companies said they know the number of log-ins that could be attributed to vendors, and that less than 50% enforce policies around third party access. Furthermore, 69% of respondents said they definitely or possibly suffered a security breach accomplished through vendor access in the past year.

Lets not forget that the Target breach of 40 million credit cards and 70 million customer records was caused by the weak security of one of Target's HVAC vendors. It cost Target over $300 million and the jobs of everyone on the leadership team as well as lasting damage to the store's reputation. In addition, it resulted in two expensive class-action suits, one by customers and one by investors peeved at the loss of Target's stock price following the incident.

The consensus by security professionals is that the risk posed by third parties is not only substantial, but it is increasing each and every year. Gartner stated in its June 2017 Magic Quadrant for IT Vendor Risk Management that by 2020, 75% of Fortune Global 500 companies will treat vendor risk management as a board-level initiative to mitigate brand and reputation risk.

So why is it then, that health system CEOs are focused on other things? It could be that the healthcare industry has too many challenges, and third party vendor risk management (TPVRM) is just further down the list. It could also be the fact that very few healthcare delivery organizations feature in the prestigious Fortune 500 list, or it could just be that healthcare CCOs, CROs and CISOs, just haven't got the message across to their CEO yet. Either way they must prioritize their risk management strategies or they could suffer irreparable damage.

Mitigating NHS Cyber Risks

The UK National Health System is about to start connecting many of its medical devices to the healthcare network as part of its latest efficiency drive, but what does this mean for the cybersecurity of medical networks and to patient safety?

Gulf Critical Infrastructure: Protecting What Matters Most

Richard Staynings with Padam Kafle, Head Of Information Technology & Automation, Aster Hospitals, UAE, Nada Chehab, Director of Clinical Education, American Hospital Dubai, Dr Mustafa Hasan Qurban Ph.D, CIO of King Fahd Military Medical Complex, Saudi Arabia, Ahmad Yahya, CIO, American Hospital Dubai, & Himanshu Puri, CIO, Kings College Hospital London UAE.

Protecting GCC critical infrastructure industries from increasingly frequent and ever more devastating cyber-attacks is a concern for many of us. But when attackers focus their attention on medical systems that keep people alive, then it becomes a major concern for every GCC national government and a matter of national security.

Growing digital interoperability of health information technology has combined with a massive increase in connected medical devices and a rising popularity of medical wearables, to greatly expand the potential attack surface. Highly valuable PHI, PII, clinical research, and innovative new procedures has made the theft of healthcare data very lucrative for both cyber criminals and pariah nation states. 

The criticality of national critical industries including healthcare has also made the industry a popular target for ransomware cyber-extortion gangs as well as proxies for pariah nation states wishing to coerce or to send a less than diplomatic message to the peoples and governments of nations that refuse to back totalitarian autocracy and global power plays. 

2021 set new record highs for global healthcare data breaches. An increase of 32% over 2020. But the risk is not just data theft, extortion and other attacks against systems availability are now a major risk to patient safety. In 2021, governments worldwide saw a 1,885% increase in ransomware attacks, and the health care industry faced a 755% increase in ransomware attacks. The threats are plainly increasing but are we adopting the right approach to cyber defence?

Richard Staynings gives the opening keynote to a packed house of technology senior executives from across the GCC region at the Shangri-La in Dubai.

This was the subject to my opening keynote address to the CIO Middle East Conference in Dubai today where I had the pleasure to address the region's top executives technology and security leaders including a healthcare panel with Padam Kafle, Head Of Information Technology & Automation, Aster Hospitals, UAE, Nada Chehab, Director of Clinical Education, American Hospital Dubai, Dr. Mustafa Hasan Qurban Ph.D, CIO of King Fahd Military Medical Complex Saudi Arabia, Ahmad Yahya, CIO, American Hospital Dubai, & Himanshu Puri, CIO, Kings College Hospital London UAE.

Balancing patient-centric care and privacy protection with new cybersecurity risks is a new concept to much of the Gulf, but risks are a growing concern and a major distraction from improving patient care and outcomes which help to drive improvements in population health.

Ransomware Gang Demands $10m to restore French Hospital

The Center Hospitalier Sud Francilien (CHSF), a 1000-bed hospital located in Corbeil-Essonnes 28km SE from the center of Paris, has been virtually paralyzed by a cyberattack. Nearly all IT systems appear to have been taken off-line by a ransomware attack discovered on August 21, which has resulted in the medical center referring patients to other establishments and postponing appointments for surgeries. Non-critical services have had to be directed elsewhere, and staff are now working with limited resources.

"Each day we need to rewrite patients' medications, all the prescriptions, the discharge prescriptions," said Valerie Caudwell, the president of the medical commission of the CHSF hospital. "For the nurses, instead of putting in all the patients' data on the computer, they now need to file it manually from scratch."

Medical imaging has been particularly impacted resulting in all PACS and other imaging services currently being off-line. Many medical devices were highly susceptible to the cyber-attack and may have been at the core of the ransomware attack. Like most hospitals, patching of medical devices against known security vulnerabilities appears to have been lax, making them an easy target for hackers to establish a foothold on the medical network.

“Without security enclaving or segmentation of vulnerable medical devices, these systems wouldn’t have stood a chance,” claims Richard Staynings, Chief Security Strategist at healthcare security company Cylera. “It’s impractical or impossible to patch devices where manufacturers have not released a patch, so you really need to isolate high-risk systems as a form of compensating security control,” he added.

CHSF serves an area of 600,000 inhabitants, so any disruption in its operations can endanger the health, and even lives, of people in a medical emergency. Unlike a similar ransomware attack in 2020 against Düsseldorf University Hospital, where a 78 year old woman suffering from an aortic aneurysm died after being redirected to a different hospital 32km away, no deaths have been reported at CHSF.

The hospital has refused to pay a ransom demand of ten million dollars and is rebuilding its IT systems from scratch while restoring patient data from backup, a process which it expects to take many days.

Police specializing in cybercrime are investigating. Cyber-attacks targeting hospitals in France have been increasing recently, with 380 last year, a 70 percent rise from 2020.

"An investigation for intrusion into the computer system and for attempted extortion in an organized gang has been opened to the cybercrime section of the Paris prosecutor's office," a police source told Le Monde, also specifying that "the investigations were entrusted to the gendarmes of the Center fight against digital crime (C3N)".

While police and cybersecurity experts continue to investigate this attack, “the Tactics, Techniques, and Procedures (TTPs) indicate a LockBit 3.0 infection,” according to Jordan Rogers, head of cyber threat intelligence at Cylera. However, if LockBit 3.0 is responsible for the attack, it will violate the Ransomware as a Service (RaaS) program's rules, which prohibit affiliates from encrypting systems of healthcare providers.

At this time, the attribution to the particular threat group hasn't been confirmed yet, and LockBit 3.0's extortion site contains no entry for CHSF yet, so their involvement remains a hypothesis. Gang affiliates using this RaaS are known to operate primarily in Russia and Belarus.

NHS 111 Services Held to Ransom by Cyber Attack

NHS 111 services are down for much of the UK following a cyber-attack Thursday morning against the infrastructure of software vendor 'Advanced'. The company's Adastra system is used by call handlers to dispatch ambulances, to book urgent care appointments, and for out of office hours emergency prescriptions. It’s Caresys software is used extensively across more than 1,000 care homes, while Carenotes, Crosscare and Staffplan are used extensively by providers. Advanced supplies software to NHS facilities and doctors nationally, including hospitals, doctors’ offices, care homes and mental health services, so disruption has been widespread.

The systems outage is causing significant delays as call handlers are forced to use other systems or to revert to paper. Emergency ambulance dispatch is taking priority it has been reported, meaning that everyone else has to wait. Meanwhile, applications managed by Advanced have been isolated to prevent lateral spread of malware to other NHS systems.

According to the Telegraph, the cyber-attack appears to have been conducted by an organized criminal ransomware group looking to shut down crucial systems rather than a hostile state-actor as had been originally feared. Healthcare and other critical national infrastructure services have been on high alert since the start of the war in Ukraine given heightened tensions with Moscow. The UK’s National Cyber Security Centre is working with the NHS as it attempts to recover systems from backups and restore services.

UK businesses have been warned about paying ransoms and incentivizing extortionists. According to the Telegraph last month, the head of the UK’s National Cyber Security Centre (NCSC) and the Information Commissioner warned businesses that they risked “incentivizing” attacks by cybercrime gangs by paying ransom demands.

According to Sky News, Advanced, said the issue was contained to "a small number of servers" representing 2% of its health and care infrastructure. Chief operating officer Simon Short added: "We continue to work with the NHS and health and care bodies as well as our technology and security partners, focused on recovery of all systems over the weekend and during the early part of next week."

This latest cyber-attack against the NHS is an unwelcome test of its resiliency and preparedness for various outages including cyber-extortion. As a critical infrastructure industry, the NHS is a target for pariah nation state attack, although in this case evidence appears to suggest that the attack was orchestrated by a Russian criminal gang. Given the known close working relationship between the Russian government and the country’s organized crime gangs, the Kremlin may not be entirely off the hook in this case. A forensic investigation of the cyberattack will take time and a positive attribution of the attackers may be many months away.


NSH 111 services previously known as ‘NHS Direct’ is used for non-emergency Urgent Care services and puts callers in touch with highly trained advisers supported by healthcare professionals. It was designed to reduce the call volume on the UK’s 999 Emergency services (similar to the US’s 911 call system) for non-critical healthcare issues, or to force patients to have to wait several days for an appointment with their general practitioner / primary care provider. The free 111 service is widely used and can be accessed by anyone dialing the number from within the UK.

Advanced is owned by Vista Equity Partners and BC Partners.

Meta sued for violating patient privacy

Facebook’s parent company Meta is facing two proposed class-action lawsuits for using the Meta Pixel tracking tool on health system websites to target ads.

This is not the first time that Meta-Facebook has been dragged through the courts and sued for a breach of privacy. In this case the problem stems from the company’s wholesale vacuuming up of all kinds of metadata whenever a user visits a web page containing its Pixel tracker functionality.


Pixel is contained in a few lines of JavaScript code and is found widely embedded into various web applications. It appears unlikely that the providers using these web applications were aware of the code contained in their portal pages, or that highly confidential HIPAA protected information is being sent to and used by Meta-Facebook without patients' express written permission being obtained. This is especially so because Meta is not a duly authorized HIPAA Business Associate, a requirement before HIPAA Covered Entities (CE) can share protected health information with a third party, nor is Meta a HIPAA CEin its own right. Based upon recent research, it’s probable that hundreds of healthcare portals contain the Meta Pixel code unbeknownst to most providers and that millions of patients could be affected.


The big question is whether Meta Corporation failed to realize that it was illegally being sent PHI data from Pixel, as it continued to monetize this data to sell directed advertising to unsuspecting patients. This point may become a pivotal argument in pending lawsuits and any regulatory enforcement actions. Based upon previous privacy violations, Meta-Facebook is supposed to have implemented business tools to identify sensitive health data and to filter this out from its advertising revenue generating systems. 


In what will likely be a double blow, the collected data was not just innocuous de-identified medical information. “The data Meta received reportedly contained medical symptoms & conditions, prescription information, doctors’ names, IP addresses, and other data defined as HIPAA identifiers. It would therefore be relatively easy to reverse engineer this PHI data to determine the patient identity. It all comes down to the number of data points held in the Meta advertising database,” claimed Richard Staynings, Chief Security Strategist with Cylera. “This could end up being labeled as a massive breach of highly sensitive and confidential regulated HIPAA data.”


In addition to the recently announced class action it seems likely that the Office of Civil Rights (OCR), the enforcement division of Health and Human Services (HHS) is spinning up a task force to investigate this breach and will be assigning a large team to examine potential violation of  HIPAA, the 1996 federal Health Insurance Portability and Accountability Act.

Not only does Meta Corporation likely face HIPAA regulatory concerns, but it also seems likely that various states Attorney Generals (AGs) will be looking very carefully to determine if the Pixel code is present in their jurisdictions on web pages where there is an expected right of privacy. This is especially so on healthcare portals. Finally, it also seems likely that OCR and AGs will be looking carefully at healthcare providers to examine their policies, standards, procedures and guidelines around due-diligence for acceptance of web application technologies and enabled functionality.


“This is an extreme example of exactly how far the tentacles of Big Tech reach into what we think of as a protected data space,” said Nicholson Price, a University of Michigan law professor who studies big data and health care. “I think this is creepy, problematic, and potentially illegal” from the hospitals’ point of view.


In 2019, the Federal Trade Commission (FTC) imposed a $5 billion penalty on Facebook and required it to submit to new restrictions and requirements to hold the company accountable for its data privacy decisions. This included the promised use of a sensitivity filtering mechanism.
 

Systemic Problem

Many of these privacy issues stem from a fundamental imbalance between the rights of individuals in the United States to remain anonymous and their data kept private, versus the rights of large corporations to collect and mine data for profit. This is a balance that has been addressed in Europe through GDPR - the 2016 General Data Protection Regulation which has quickly become a global standard for Privacy outside of the United States.
 
The federal nature of the US however has resulted in 50 very different and separate state privacy regulations that make it hard to enforce privacy standards for individuals given so much cross-state commerce. Attempts by the federal government to catch up to other OECD nations with a revised national privacy act have met with opposition from some states concerned that a federal law will dumb down their existing provisions, while other state representatives oppose the imposition of something similar to GDPR which they regard as an undue constraint on businesses. 
 
The latest in a long line of attempts to update US privacy laws is currently working its way through congress. It remains to be seen whether the highly fractured nature of US law making results in national privacy changes or goes the way of prior attempts.

How Concerned Should we be about a Russian State Cyberattack against the US?

Russia’s invasion of Ukraine appears to be bogged down if the reports coming out of the country are to be believed. Indeed troops around Kyiv are currently reported to be withdrawing back to Belarus to regroup and re-arm. The surgical Blitzkrieg to take over the country and replace its elected leaders with Putin-friendly surrogates has failed, and now Russia has been forced to re-evaluate its military objectives and to focus on liberating Donbas and Luhansk from Ukraine and the Ukrainian people who live there. The area is one of many across the former Soviet Union seeded by Stalin with Russian diaspora after annihilating much of the indigenous population in one of many genocidal purges of opponents. In this case, it was a mass purge of Ukrainians.
 
Indeed the Holodomor (Ukrainian: Голодомо́р) in which 4 million Ukrainians were purposely starved to death by Stalin between 1932 and 1933 in order to suppress Ukrainian desires for independence, is perhaps one of the reasons why Ukraine has been so vociferous in its defense against Russian invasion.
 

An Invasion Falling Apart

But as casualties mount, and in particular the deaths of a large number of Russian General Officers, Putin’s hold over the military and therefore political power, looks to be increasingly tenuous. Reports in the media of tanks being driven over commanding officers by unhappy starving soldiers who were misled and lied to by their leadership, poorly trained and led troops shooting unarmed civilians indiscriminately, and a growing realization by Russian troops that they are pawns in an illegitimate conflict with neighbors most of whom speak their own language, is drawing into question the abilities of the Russian military and its leadership.
 
As the Russian body bag count continues to rise and a growing number of funerals are announced back home in Russia of all kinds of senior military officers, so the public will increasingly be aware of the costs of Putin’s folly. The closure of most foreign stores, the inability to fly anywhere as planes are grounded, and a Ruble which has structurally lost 40% of its value since February will be sure to reinforce concerns that Putin is engaged in a conflict much bigger than he has led on.

 

But military power is not all that Putin can muster in his battle with the west. As President, Putin has at his disposal the considerable state cyber forces of the Russian FSB and GRU. These are groups with no shortage of highly destructive cyber weapons, many of which have been used against Ukraine since 2015, and some of which date to the cyber-attacks against Georgia, Estonia, Azerbaijan, and Chechnya,  all the way back to the 1990s. 
 
Putin also has access to the considerable forces of Russian organized cybercrime in return for historically turning a blind eye to their lucrative criminal activities. Indeed, some investigators have concluded an even tighter more collaborative relationship between the Russian President and mob bosses. Putin in other words, has many options open to him for direct and indirect cyber-attacks, though few would believe any claims in current times that Russian organized crime totally operates outside of the influence of Putin and the Kremlin.
 

Russia and Cyberwarfare

The west has in fact been in an ongoing cyberwar with Russia since the turn of the millennium when Russian gangs realized that they could operate their craft of cyber theft and extortion with total impunity from within the bounds of the Russian Federation. Putin and the almost ineffective forces of Russian law enforcement simply turned a blind eye to the gangs and their activities. Perhaps the reported back-handers to police officers helped. Perhaps the sheer power of these gangs was enough to intimidate law enforcement officers. Either way, the illicit foreign exchange inflows of untraceable cryptocurrency continues to boost the struggling Russian economy.

 

The connection between Russian organized crime syndicates and the Kremlin in recent months looks to be a lot less deniable, with evidence suggesting that crime gangs are acting on instruction from the Kremlin and perhaps maybe receiving payment for the acquisition of intelligence gained in their attacks. Take for example the SolarWinds Orion attack, which was attributed to ‘Nobelium’, a group reportedly being directed by the Russian intelligence to infiltrate US federal agencies, while another Russian cybercrime group, ‘DarkSide’, was busy at the exact same time with a high profile and distracting ransomware attack against the Colonial Pipeline cutting off fuel supplies to the southeast of the entire United States.
 

Is Putin likely to respond to increasing western military support of Ukraine?

So far at least, Putin appears to have held back his arsenal of cyber weapons. Supposition is that Putin is concerned that any massive cyber-attack against the west would be sure to result in a powerful response from the west against Russian critical infrastructure including the power grid. It would then be almost impossible for Putin to continue to dupe the Russian people with propaganda stories of an almost insignificant special military operation to rid Ukraine of Nazis. The cat would be out of the bag regardless of whether conscript bodies are returned to their mothers or not, and Putin would be facing enemies from within as well as abroad. It was the unpopularity of the wars in Georgia and Chechnya back home that forced a Russian withdrawal, and the unpopularity of the war in Afghanistan that eventually bankrupted and lead to the collapse of the Soviet Union before it.
 
Indeed, this is perhaps what Putin fears most – a popular uprising against his rule by the very lumpenproletariat he claims to represent. So far however, the Kremlin propaganda machine still appears to be working well and Putin can claim wide-scale popular support at home from the babushkas that believe everything they are told by the state media outlets.

 

While Russia may have some devastating cyber weapons up its sleeve, the NSA is widely regarded to have bigger more devastating cyber weaponry in is arsenal. These include weapons able to effectively take Russia back to the nineteenth century and presumably include the capability to turn off Russia’s power grid, its water, oil, and gas systems, its flight control systems, transportation, and a heap of other critical infrastructure. This would deny Russians, and the Russian war machine with the ability to operate at anything other than at minimal levels and could wreak havoc on military resupply and other logistics.
 
The NSA is not alone however, other Five Eyes nations are thought to have comparable cyber capabilities and would no doubt respond as a group if attacked by Russia. The EU is thought to also have some offensive cyber capabilities, while Israel, less involved in the support of Ukraine against Russian invasion, would likely join in to support the USA and its other allies, despite its current free pass from Russia to attack Hezbollah terrorists operating inside Syria in return for staying neutral. Israel is thought to have some very nasty tricks up its sleeves and based upon its past performance, is less inclined to hold back if ever attacked.
 
So with cyber armies lined up against each other, perhaps we have reached the modern day equivalent of Mutually Assured Destruction (MAD). This was a principle that ensured the global peace between totalitarian east and liberal democratic west, around the use of nuclear weapons from the late nineteen forties to the present day. Given the impact to all of us of an all-out cyberwar between Russia and the west, let’s hope that MAD will keep the cyber weapons firmly locked up.
