Apple released updates for a variety of its products to patch recent vulnerabilities found in Siri, the Apple iOS digital assistant.

The vulnerabilities could allow an attacker to steal information through a locked device because when a device is locked, there are still voice commands that the digital assistant can process and may allow access to contacts and other sensitive data.

In its latest round of fixes, Apple restricted these options to prevent malicious actors from exploiting the vulnerability, even if they have physical access to a device.

In addition to the iPhone, the company patched a similar vulnerability in Apple Watch, iOS, iPadOS, and the macOS Ventura.

Users should update to the latest software version of iOS and iPadOS, iOS 17.6, or iPadOS 17.6, to mitigate these bugs by going to settings, general, and then software update.

Siri Bug Enables Data Theft on Locked Apple Devices

The sustained cyberattack, likely made worse by a mitigation snafu, disrupted several Azure cloud services for nearly eight hours on July 30.

Microsoft blamed an implementation error for amplifying the impact of a distributed denial-of-service (DDoS) attack yesterday, which ended up disrupting the company's Azure cloud services for nearly eight hours.

The attack affected several Azure offerings, including Azure App Services, Azure IoT Central, Application Insights, Log Search Alerts, and Azure Policy. The disruption, which began at around 7:45 a.m. ET and lasted until 3:43 p.m. ET, also impacted the main Azure portal and a subset of Microsoft 365 and Microsoft Purview data-protection services.

**DDoS Cyber-Defense Error Under Investigation**

In an event summary yesterday, Microsoft described the DDoS attack as causing an "unexpected usage spike \[that\] resulted in Azure Front Door (AFD) and Azure Content Delivery Network (CDN) components performing below acceptable thresholds." The spike caused intermittent service errors, timeouts, and sudden latency increases.

More concerningly in some ways, "while the initial trigger event was a DDoS attack, which activated our DDoS protection mechanisms, initial investigations suggest that an error in the implementation of our defenses amplified the impact of the attack rather than mitigating it."

Microsoft has not specifically identified the mistake that exacerbated the DDoS attack. But according to its description of the events of July 30, the initial network configuration changes the company made to support DDoS mitigation efforts may have led to some unexpected "side effects." The company implemented an updated approach that it first rolled out in thbe Asia-Pacific region and Europe, and then deployed in the Americas after validating the approach worked.

"Our team will be completing an internal retrospective to understand the incident in more detail," Microsoft said. "We will publish a Preliminary Post Incident Review (PIR) within approximately 72 hours, to share more details on what happened and how we responded."

**Inadvertent Errors in DDoS Mitigation**

Rody Quinlan, staff research engineer at Tenable, says there are several ways an organization can mess up a DDoS mitigation effort.

"Organizations can inadvertently amplify cyberattacks through various implementation errors, such as misconfigured rate limiting, inefficient load balancing, firewall misconfigurations, overly aggressive security rules, inadequate resource scaling, incorrect traffic filtering, and dependence on single points of failure," he says. "These errors can lead to blocked legitimate traffic, overloaded servers, bottlenecked firewalls, and critical services being taken offline."

And while Microsoft's initial response might have contributed to its Azure service problems this week, the incident is another reminder of how effective DDoS attacks remain for adversaries looking to disrupt and degrade a target's online presence.

A Cloudflare report earlier this year identified a 117% increase year-over-year in network-layer DDoS attacks. Part of the reason for that is a specific increase in DDoS attacks that targeted retail, shipping, and public relations websites on and around Black Friday and the holiday shopping season in general. However, many of the attacks have also been by groups looking to send out a specific message or convey a particular political stance. Cloudflare, for example, said it has observed a massive increase in DDoS attacks that target Taiwanese, Israeli, and Palestinian sites amid geopolitical tensions in those areas, and attacks on environmental sciences websites.

**DDoS Attacks Adopt "Smash & Grab" Tactics**

"Trends in DDoS are often cyclical, but currently we’re seeing attacks grow larger in size, and shorter in duration," says Donny Chong, director at DDoS security vendor Nexusguard. "Our most recent data suggests that attack sizes increased by an average of 183% last year, with an average size of 0.80Gbps," he says. At the same time, between 2022 and 2023, the average duration of DDoS attacks dropped to just over 101 minutes. Currently, 81% of DDoS attacks last less than 90 minutes, Chong says.

"Part of this decrease in attack duration is due to attackers becoming more and more efficient when inflicting disruption on business," likely because they are using artificial intelligence (AI) to automate some attacks. But the shorter attack durations are also likely due to mitigation technologies, Chong says. "\[Attackers\] are finding it increasingly difficult to sustain prolonged disruptions. So, rather than a prolonged siege, it's now more a case of ‘smash and grab,'" he says.

Quinlan says the key to mitigating DDoS disruption is having a real-time traffic analysis capability, scalable cloud infrastructure, redundant systems, and intelligent load balancing to prevent overload. "Proper rate limiting, throttling, and WAFs \[Web application firewalls\] filtering malicious traffic, and regular software and hardware vulnerability remediation is crucial to protect systems," Quinlan says. "An effective incident-response plan and collaboration with Internet service providers and security providers enhance detection and mitigation capabilities."

Microsoft: Azure DDoS Attack Amplified by Cyber-Defense Error

Two US senators accuse carmakers of deceptive language and shifty practices in sharing and resale of driver data.

Two US senators have called on the US Federal Trade Commission (FTC) to hold automakers accountable for sharing driver data without consent, highlighting the growing data privacy challenges — and deceptive verbiage from terms of service — associated with modern smart cars.

In a letter to the FTC (PDF) last week, Sens. Ron Wyden (D-Ore.) and Edward Markey (D-Mass.) used the data-sharing practices of General Motors, Honda, and Hyundai as symptomatic of an industrywide problem that needs immediate investigation.

**Data Sharing Without Consent**

All three vendors collected and sold driver information such as acceleration and braking data to Verisk, a data analytics company that used the information to prepare driver behavior reports that it then resold to insurance companies. By their own account, none of the automakers obtained informed consent from customers before sharing their information. Instead, they deliberately obscured their data-sharing relationship with Verisk in lengthy disclosures and made deceptive claims about how they would use driver data, the senators charged.

"The FTC should hold accountable the automakers, which shared their customers' data with data brokers without obtaining informed consent, as well as the data brokers, which resold data that had not been obtained in a lawful manner," their letter noted. "Given the high number of consumers impacted, and the outrageous manipulation of consumers using dark patterns, the FTC should also hold senior company officials responsible for their flagrant abuse of their customers' privacy."

The letter highlights just one aspect of what many say is a rapidly growing set of security and privacy issues around modern, highly connected software-defined vehicles. While such vehicles offer increased automation, autonomous capabilities, and highly customizable user experiences, they also collect an enormous amount of data that can be hard to protect and secure.

"Your vehicle knows your name, your home address, your debit/credit card info, how fast you drive, how hard you brake, what you ask its voice assistant, the locations you frequent and at what times," says Riley Keehn, lead regulatory and government affairs consultant for SBD Automotive, an automotive research and consulting firm. "Certain occupant detection and automated driving cameras and sensors can even see you and your surroundings."

The onboard storage of this sheer volume of personal and identifying information (PII) and sensitive data types make drivers and their vehicles the direct targets of cyberattacks. These attacks can happen via hardwired systems like the OBD-II port or even the headlights, connections to the vehicle via shared and insecure Wi-Fi networks, through electric vehicle charging stations, compromised aftermarket components, and other means, Keehn says.

Some of these risks can be addressed via security-by-design approaches and the implementation of industry best practices and regulations, such as UN R155 on Cybersecurity Management Systems (CSMS) and UN R156 on Software Update Management Systems (SUMS), ISO/SAE 21434:2021 on Cybersecurity Engineering for Road Vehicles, and other international and regional requirements, she notes.

**A Complete Lack of Consumer Privacy Protections?**

But where things can get messy is what happens to personal data after a vehicle collects it. "The US still lacks a comprehensive, general data privacy regulation comparable to the EU's GDPR, China's PIPL/DSL/CSL framework, and other global regulations that have adopted the GDPR's model and stringency," Keehn says.

The US largely relies on sector-specific regulations, such as HIPAA in healthcare, to address unique data privacy and security requirements. Individual states have filled that gap with their own data privacy laws, creating a patchwork of inconsistent rules, often exempting certain sectors and technologies. While some states may have clear requirements for how an original equipment manufacturer (OEM) must handle the storage, collection, sharing, and sale of data, other states may have different requirements or none at all, she says.

"This inconsistency and lack of national guidance in the US creates a host of risks at the business level and can foster an OEM culture where security stops with the vehicle," Keehn adds.

**Can the FTC Really Drive Change?**

David Brumley, CEO of software security firm ForAllSecure, says car companies should be required to ask for informed consent from drivers to share their information for advertising or for any other purpose not specific to delivering a required feature. 

"Over-the-air software updates? Probably being served from Amazon or Google. Maps? Probably from a third-party. Accurate position? It's not just GPS; often it's assisted with other metadata — like Swift Navigation — to increase accuracy," Brumley notes.

A car vendor might require some data, like location information, for instance, to provide services such as roadside assistance, traffic warnings, and autonomous driving. So there needs to be separate consent requirement for sharing such data and for sharing data for pure profit reasons, he says. "Second, we need a law that says companies must not limit functionality when someone opts out," he adds. "Someone shouldn't be able to force your consent so you can keep driving to work."

Brumley says it's unrealistic, however, to expect the FTC to drive much change. "They don't exercise their regulatory powers in other domains, and instead rely on free-market" dynamics, which won't help here, he says. "Where we may get a bump is EU regulations, which tend to be stricter.  We also need consumers to speak up that it impacts their buying decisions."

Smart Cars Share Driver Data, Prompting Calls for Federal Scrutiny

The security vulnerabilities, CVE-2024-37394, CVE-2024-37395, and CVE-2024-37396, could lay open proprietary and sensitive research to data thieves.

Researchers have discovered three cross-site scripting (XSS) vulnerabilities in Research Electronic Data Capture (REDCap), a Web application developed by Vanderbilt University and used for building and managing online surveys and databases for scientific and academic researchers.

The vulnerabilities are tracked as CVE-2024-37394, CVE-2024-37395, and CVE-2024-37396, and they "could allow attackers to execute malicious JavaScript code in victims' browsers, potentially compromising sensitive data," according to an advisory from Trustwave's SpiderLabs.

Researchers there identified the vulnerabilities in multiple locations within version 13.1.9 in REDCap, which is popular in universities and scientific institutions for managing studies that contain private, sensitive information. The vulnerable locations in the platform include calendar events, public surveys, and project dashboards.

"Our researchers developed proof-of-concept exploits for each vulnerable location," the researchers wrote. "In each case, they were able to inject a simple JavaScript payload that, when triggered, executes an alert displaying the document domain."

The vulnerabilities could allow threat actors to steal sensitive information, impersonate the victim's actions, manipulate the REDCap application, and even gain access to protected data.

It's recommended that users update to REDCap version 14.2.1 or later, where Vanderbilt University has addressed these bugs, to mitigate these flaws.

If paying a ransom is prohibited, organizations won't do it — eliminating the incentive for cybercriminals. Problem solved, it seems. Or is it?

COMMENTARY

Ransomware and other malware attacks are among the top three types of security incidents that organizations experience, according to Netwrix's "2024 Hybrid Security Trends Report." In a bid to curb this menace, for several years now there have been discussions around a radical approach: making ransomware payments illegal. The rationale is straightforward. If paying a ransom is prohibited, organizations won't do it — thus eliminating the incentive for cybercriminals to launch ransomware attacks. Problem solved. Or is it?

**All Ransoms Are Not Equal**

We must first recognize that there are multiple types of extortion. Ransomware is generally different from physical extortion cases like kidnappings, hostage situations, and threats of violence against individuals or public spaces. However, a ransomware attack, for example, on a hospital, literally endangers patients' lives. 

In scenarios where human lives are directly at stake, the ethical and legal considerations surrounding ransom payments are more complex than a simple ban allows for. Given the adaptability and resourcefulness of ransomware attackers, it is highly likely that they will push the boundaries of such a ban and test the limits of enforcement. As a result, a blanket ban on all ransom payments could force decision-makers into impossible moral dilemmas.

**The Law of Unintended Consequences**

Let's suppose for a moment that ransom payments have been legally prohibited, and a ransomware attack has just crippled your business. You need to get back online quickly or your business may go under. While the law forbids you from paying the ransom, enforcement agencies cannot stop what they don't know about. Almost certainly, some companies would quietly pay the ransom and simply not report the incident. This hesitancy to report attacks affects visibility into the actual scope of the problem and hinders law enforcement from acting accordingly. If the challenge is unknown, it cannot be addressed. 

In addition, there would be a disproportionate impact on small and medium-sized businesses. While large organizations might possess the resources to endure a ransomware attack without caving in to ransom demands, small businesses could face existential threats. A blanket ban on ransom payments could leave them in a precarious position of having to choose between resorting to illegal payments or risking going out of business.

**Case in Point: Cyber Insurance **

No legislative action or policy change occurs in isolation; it inevitably has ripple effects and unintended consequences. Cyber insurance provides a prime example in the arena of ransomware. By securing a cyber-insurance policy, businesses aim to protect themselves from the financial fallout of a ransomware attack, as the insurance provider would cover the ransom payment. 

Indeed, this is how it worked just several years ago. However, cybercriminals quickly recognized that insured organizations are more likely to pay ransoms, since their insurance company covers these expenses. It is reasonable to assume that threat actors started conducting reconnaissance on the cyber-insurance coverage of potential victims to tailor their attacks and maximize their profits. This is how cyber insurance might have contributed to the growth of the ransomware epidemic. 

Currently, one can hardly find an insurance company ready to reimburse the ransom payment.

**A Better Model: Follow the Banking Industry**

Bank robberies were once a prevalent threat, but they have significantly declined in recent decades. This reduction was not achieved by banning bank tellers from handing over cash. Instead, banks have adopted a multifaceted approach to mitigate the risk. To deter potential robbers, they use measures such as reduced cash handling, time-lock safes, enhanced security cameras, and alarm systems. Dye packs, decoy money, and GPS trackers reduce the risk of financial loss in cases where cash is ultimately handed over. What's more, appropriate security measures are a must to obtain and keep the license to operate. 

A similar approach may prove equally effective for other high-risk industries. Governments can establish cybersecurity benchmarks and recommend risk mitigation strategies, just as they have for the public sector and critical infrastructure. Such standards offer essential guidance for organizations that lack the strategic leadership necessary to develop an effective ransomware defense strategy independently. 

Finally, law enforcement agencies take their share of the responsibility and increase international collaboration to dismantle ransomware networks. The benefits of this approach are already paying off, as evidenced by the recent takedown of the LockBit ransomware gang. Agencies from more than half a dozen countries issued a detailed joint cybersecurity advisory that outlined LockBit's tactics and tools. They also seized some of the group's attack assets, significantly hindering their ability to initiate attacks.

**Conclusion**

Frustration is understandable as ransomware attacks continue around the globe, but simply denying victim organizations the option of paying the ransom is neither realistic nor practical. There will always be exceptions to the law, and unanticipated repercussions could make the cure worse than the disease. Instead, an effective response will require organizations to take greater responsibility for cybersecurity and government agencies to engage in good old-fashioned police work. This strategy may not be as straightforward as a ban on ransom payments, but the war against ransomware is winnable through a comprehensive, nuanced approach.

A nation-state cyber-espionage group linked to India has broadened its targeting beyond regional rivals in Pakistan, Afghanistan, China, and Nepal and is focused on compromising computers and networks at maritime facilities in countries as far away as the Mediterranean Sea.

The group — known variously as SideWinder, Razor Tiger, and Rattlesnake — commonly wages spear-phishing attacks using images of official-looking documents. In its latest campaigns, SideWinder has falsified documents from specific ports, including the Port of Alexandria in Egypt, with high-interest topics such as job termination and salary reductions, researchers from BlackBerry said in a newly published advisory.

While the group has typically focused on rivals closer to home and is less prolific than other cyber spies, the current campaign suggests that they have expanded their targeting, says Ismael Valenzuela, vice president of threat research and intelligence at BlackBerry.

"It's the first time we have seen SideWinder targeting ports and maritime facilities in EMEA," he says. "We see a lot of geopolitical turbulence and \[changing\] environments across the globe on a variety of issues. This often galvanizes threat groups and state-sponsors to specifically strike down critical assets, like those within the maritime industry."

The maritime industry increasingly has become a target of cyberattacks, posing serious danger to ships and ports. In 2019, the US Coast Guard warned shipping companies that attacks on their systems could lead to accidents and catastrophes. In the past year, following increased Chinese cyber operations against critical infrastructure including maritime systems in and around the South China Sea, various countries in the Asia-Pacific region have banded together to protect their networks and systems.

The cyber warnings also come as physical threats to shipping increase as well. Piracy off the Atlantic coast of Africa and the Arabian Sea, and among the island nations of the Asia-Pacific, has escalated, while ship malfunctions — such as the one the caused a vessel to collide with the Baltimore bridge — have become more frequent.

**New Phishing Lures, Old Exploits**

SideWinder has conducted attacks since at least 2012. The group is relatively sophisticated, commonly using encrypted malware samples, various obfuscation techniques, and running code in memory to avoid file scanners, according to a presentation at Black Hat Asia in 2022. From 2020 to 2022, the group conducted more than 1,000 attacks, Noushin Shabab, senior security researcher with Kaspersky, said during that presentation.

"I think what truly makes them stand out among other APT \[advanced persistent threat\] actors is the large tool set they have with many different malware families, lots of new spear-phishing documents, and a very large infrastructure," Shabab said. "I haven't seen 1,000 attacks from a single APT" from another group thus far.

However, the current cyberattacks are, in many cases, using older vulnerabilities, such as a flaw in Microsoft Office dating back to 2017. The vulnerability (CVE-2017-0199) allows remote code execution against old versions of Microsoft Office and Windows, and has been a very popular vector of attack, with more than 5,600 malware samples exploiting the issue this year, including 15 malicious samples reported from Egypt, according to BlackBerry.

Like most groups, SideWinder does not like to waste a good exploit, even if it's seven years old, says Valenzuela.

"Why do we still see old CVEs like these exploited in the wild? Attackers know that many organizations don’t patch their Office software for many years," he says. "This is especially common in organizations with legacy systems, which are often used in ports and maritime facilities as well as other critical infrastructure."

BlackBerry documented the use of another very popular — and seven-year-old — vulnerability, in the Microsoft Office Equation Editor (CVE-2017-11882), with more than 9,500 samples of Office documents exploiting the issue since the start of 2024. Both of these vulnerabilities have made the Known Exploited Vulnerabilities list maintained by the Cybersecurity and Infrastructure Security Agency (CISA).

**Maritime Under Attack**

BlackBerry's threat researchers discovered a variety of domains in the first and second stages of the attack that are likely evidence of their targets, including a long list in South Asia including Pakistan, Sri Lanka, Bangladesh, Myanmar, Nepal, and the Maldives. Egyptian ports appear to be the only target outside of India's extended neighborhood.

While the country appears to be extending its reach to other regions of the world, the cyber operations are not actually targeting ports on a global scale, Valenzuela says.

"They’re certainly targeting ports in key countries where this threat actor has geopolitical interests, and that includes the Indian Ocean and the Mediterranean, \[such as\] Egypt," he says. "We don’t have information about other targets in the Mediterranean Sea at this time."

The researchers have not captured the final payload in the attacks, but based on the group's previous actions, they believe the goal is intelligence-gathering and cyber espionage, the company stated in its advisory.

India-Linked SideWinder Group Pivots to Hacking Maritime Targets

Clutch Security is the latest cybersecurity startup looking to secure and manage non-human identity.

Identity is more than just logins and passwords. Enterprise defenders now have to consider that attackers can target and breach their networks by stealing and abusing non-human identities, such as API keys, secrets, tokens, and service accounts.

Clutch Security has emerged from stealth with its Universal Non-Human Identity (NHI) Security platform to give security teams complete visibility into all of an organization's non-human identities. The platform allows security teams to understand which NHIs exist within the organization and identifies associated risks. The platform prioritizes the risks based on severity and business impact and provides tailored remediation advice to address those risks.

The modern technology stack spans cloud services, software-as-a-service applications, on-premises software, digital vaults, code repositories, continuous integration/continuous delivery pipelines, and data warehouses, which means identity and access management requires working with both human and non-human identities. Adversaries like to target NHIs because they are distributed — making them difficult to track — and usually have elevated privileges. Clutch estimated a 1-to-45 human-to-non-human ratio in many organizations.

As part of the launch, Clutch Security announced it has raised a $8.5 million seed funding round led by Lightspeed Venture Partners. The round included Merlin Ventures, Cyber Club London (CCL), and individual investors, including Exabeam co-founder Nir Polak, serial co-founder Shlomo Kramer (Imperva, Check Point, Cato Networks), and HashiCorp co-founder Armon Dadgar. Clutch CEO and co-founder Ofir Har-Chen was the former COO at Hunters.

According to the study, around 400 stolen GenAI credentials are being sold by threat actors per day.

Cybercriminals are now able to purchase Generative AI (GenAI) account credentials on underground hacker markets along with other various illegal goods, according to new research.

The GenAI credentials include those that belong to users of ChatGPT, Quillbot, Notion, Huggingface, and Replit, among many others. eSentire's cybersecurity research team found that the hackers are selling the credentials for roughly 400 GenAI accounts per day, usually stolen from corporate end users' computers after they've been infected with an infostealer.

LLM Paradise was one underground service found to be selling stolen GenAI credentials, advertising GPT-4/Clause API keys at a starting price of $15 each (the market has since closed its doors). The threat actors also have leveraged legitimate outlets, at one point advertising the illegal products on social media platform TikTok.

Ultimately, the researchers also found that the threat actors are finding a variety of ways to monetize GenAI account credentials, whether that's by creating phishing campaigns or launching malware from the accounts, producing chatbots, or stealing sensitive corporate data such as financial information or customer information.

The researchers recommend that organizations monitor employee usage of cloud-based GenAI offerings, encourage GenAI vendors to implement WebAuth in their portals, use passkey security or password best practices, and use Dark Web monitoring services.

Criminal Hackers Add GenAI Credentials to Underground Markets

With sufficient privileges in Active Directory, attackers only have to create an "ESX Admins" group in the targeted domain and add a user to it.

Source: Schoening via Alamy Stock Photo

Multiple ransomware groups have been weaponizing an authentication bypass bug in VMware ESXi hypervisors to quickly deploy malware across virtualized environments.

VMware assigned the bug (CVE-2024-37085) a "medium" 6.8 out of 10 score on the CVSS scale. The average score is largely due to the fact that it requires an attacker to have existing permissions in a target's Active Directory (AD).

If they do have AD access, however, attackers can cause significant damage. With no technical trickery whatsoever, they can use CVE-2024-37085 to instantly scale up their ESXi privileges to the max, opening the door to ransomware deployment, data exfiltration, lateral movement, and more. Groups like Storm-0506 (aka Black Basta), Storm-1175, Manatee Tempest (part of Evil Corp), and Octo Tempest (aka Scattered Spider) have already tried it out, deploying ransomware such as Black Basta and Akira.

Broadcom recently published a fix, available on its website.

**How CVE-2024-37085 Works**

Some organizations configure their ESXi hypervisors to use AD for user management. It turns out that by doing this, organizations were exposing themselves to something unexpected. By default, ESXi hypervisors granted full administrative access to any member of an AD domain group named "ESX Admins."

It's unclear how the "ESX Admins" group vulnerability was introduced into ESXi in the first place—Broadcom declined to clarify when Dark Reading reached out on the question. As Microsoft noted in a blog post, there's no particular reason why the hypervisor should have expected such a domain group, or have had a rule for what to do with it. "This group is not a built-in group in Active Directory and does not exist by default. ESXi hypervisors do not validate that such a group exists when the server is joined to a domain and still treats any members of a group with this name with full administrative access, even if the group did not originally exist," the threat intel team wrote. "Additionally, the membership in the group is determined by name and not by security identifier (SID)."

Exploiting CVE-2024-37085 was entirely trivial. So long as an attacker had sufficient privileges in AD, all they'd have to do to gain ESXi admin privileges was to create an "ESX Admins" group in the targeted domain and add a user to it. They could also rename any existing group to "ESX Admins," and either wield one of its existing users or add a new one.

**The Risk with Hypervisors**

"Ransomware attacks targeting ESXi and VMs are increasingly common, especially since around 2020, when enterprises increased their move toward digital transformation and took advantage of modern hybrid cloud and virtualized on-premise environments," explains Jason Soroko, senior vice president of product at Sectigo.

For all the business sense they make, virtualized environments also afford hackers unique benefits. Hypervisors tend to run many VMs at once, making them a one-stop shop for blasting ransomware as widely as possible, and those VMs often host critical services and business data.

Their utility to hackers makes it all the more troubling that, as Microsoft noted in its blog, security products have limited visibility and protections for hypervisors. This, Soroko explains, is "due to their isolation, complexity, and the specialized knowledge required for their protection. This isolation makes it difficult for traditional security tools to monitor and protect the entire environment, and API integration limits further exacerbate this issue."

To cover for these shortcomings, Microsoft highlighted the importance of keeping up to date with patches, and practicing broader cyber hygiene around critical and vulnerable assets. "Attackers love using the path of least resistance that provides maximum opportunity," Soroko notes, adding that ransomware actors will only target these systems more and more in the future.
