Ymir Ransomware: A Rising Threat in the Cybersecurity Landscape

 

The evolving threat landscape continues to present new challenges, with NCC Group’s latest Threat Pulse report uncovering the emergence of Ymir ransomware. This new ransomware strain showcases the growing collaboration among cybercriminals to execute highly sophisticated attacks.

First documented during the summer of 2024, Ymir initiates its attack cycle by deploying RustyStealer, an infostealer designed to extract credentials and serve as a spyware dropper. Ymir then enters its locker phase, executing swiftly to avoid detection. According to an analysis by Kaspersky, based on an attack in Colombia, Ymir’s ransomware locker employs a configurable, victim-tailored approach, focusing on a single-extortion model, where data is encrypted but not stolen.

Unlike many modern ransomware groups, Ymir’s operators lack a dedicated leak site for stolen data, further distinguishing them. Linguistic analysis of the code revealed Lingala language strings, suggesting a possible connection to Central Africa. However, experts remain divided on whether Ymir operates independently or collaborates with other threat actors.

Blurred Lines Between Criminal and State-Sponsored Activities

Matt Hull, NCC Group’s Head of Threat Intelligence, emphasized the challenges of attribution in modern cybercrime, noting that blurred lines between criminal groups and state-sponsored actors often complicate motivations. Geopolitical tensions are a driving factor behind these dynamic threat patterns, as highlighted by the UK’s National Cyber Security Centre (NCSC).

Ransomware Trends and Global Incidents

Recent incidents exemplify this evolving threat landscape:

  • The KillSec hacktivist group transitioned into ransomware operations.
  • Ukraine’s Cyber Anarchy Squad launched destructive attacks targeting Russian organizations.
  • North Korea’s Jumpy Pisces APT collaborated with the Play ransomware gang.
  • The Turk Hack Team attacked Philippine organizations using leaked LockBit 3.0 lockers.

NCC Group’s report indicates a 16% rise in ransomware incidents in November 2024, with 565 attacks recorded. The industrial sector remains the most targeted, followed by consumer discretionary and IT. Geographically, Europe and North America experienced the highest number of incidents. Akira ransomware overtook RansomHub as the most active group during this period.

State-Backed Threats and Infrastructure Risks

State-backed cyber groups continue to escalate their operations:

  • Sandworm, a Russian APT recently reclassified as APT44, has intensified attacks on Ukrainian and European energy infrastructure.
  • As winter deepens, threats to critical national infrastructure (CNI) heighten global concerns.

Ransomware is evolving into a multipurpose tool, used by hacktivists to fund operations or to obfuscate advanced persistent threats (APTs). With its trajectory pointing to continued growth and sophistication in 2025, heightened vigilance and proactive measures will be essential to mitigate these risks.

Stolen Data
Conti Ransomware Cyber Security data security Mimic Mimic Attacks Ransomware attack Ransomware families Ransomwares Stolen Data

Understanding Mimic Ransomware: Features, Threats, and Noteworthy Exploits

 


Mimic is a ransomware family first discovered in 2022. Like other ransomware, it encrypts files on a victim’s system and demands a cryptocurrency payment for the decryption key. What makes Mimic particularly concerning is its dual approach: it not only encrypts data but also exfiltrates it beforehand. This stolen data can be used as leverage, with attackers threatening to release or sell it if the ransom is not paid. 
 
Mimic is believed to reuse code from Conti, a well-known ransomware whose source code was leaked after the group publicly supported Russia’s invasion of Ukraine. While the exact origins of Mimic remain unclear, its operations appear to primarily target English- and Russian-speaking users.   
 

Exploitation of Legitimate Tools  

 
One of Mimic’s distinctive features is its exploitation of the API from Everything, a legitimate Windows file search tool developed by Voidtools. By leveraging this tool, the ransomware can quickly locate and encrypt files, increasing the efficiency of its attacks.   
 
Importantly, Mimic does not rely on victims having Everything pre-installed. Instead, it typically packages the tool along with additional malicious programs designed to:   
 
  • Disable Windows Defender to reduce system defenses. 
  • Misuse Sysinternals’ Secure Delete tool to erase backups, making file recovery more difficult. 

Indicators of Infection  

 
Victims of Mimic can identify an infection by the “.QUIETPLACE” extension added to encrypted files. Additionally, the ransomware leaves a ransom note demanding $3,000 in cryptocurrency to provide the decryption key.   
 
In many cases, victims feel compelled to pay the ransom, particularly when backups have been deleted or compromised.   
 

The Emergence of Elpaco   

 
A new variant of Mimic, known as Elpaco, has recently been detected. This variant is associated with attacks that involve brute-forcing Remote Desktop Protocol (RDP) credentials. Once access is gained, attackers exploit the *Zerologon* vulnerability (CVE-2020-1472) to escalate privileges and deploy the ransomware.   
 
Reports of Elpaco infections have surfaced in countries such as Russia and South Korea, underscoring the expanding reach and evolving capabilities of this ransomware family.   
 

The Importance of Vigilance 

 
Although tools like Everything and Secure Delete are not inherently harmful, Mimic’s misuse of these legitimate programs highlights the need for continuous vigilance. Cybercriminals are increasingly finding ways to exploit trusted software for malicious purposes. 
 
As Mimic and its variants continue to evolve, implementing robust cybersecurity measures—including regular system updates, strong authentication protocols, and comprehensive backup strategies—remains essential to mitigating the risk of ransomware attacks.

Change Healthcare Restores Clearinghouse Services After Nine-Month Recovery From Ransomware Attack

 

Change Healthcare has announced the restoration of its clearinghouse services, marking a significant milestone in its recovery from a debilitating ransomware attack by the ALPHV/Blackcat group in February. 

The attack caused unprecedented disruption to one of the U.S.’s most critical healthcare transaction systems, which processes over 15 billion transactions annually and supports payments and communications for hospitals, healthcare providers, and patients. The breach led to widespread financial and operational issues, with the American Hospital Association (AHA) reporting that 94% of U.S. hospitals relying on Change Healthcare were affected. Many hospitals experienced severe cash flow challenges, with nearly 60% reporting daily revenue losses of $1 million or more. These difficulties persisted for months as Change Healthcare scrambled to restore its services and mitigate the attack’s impact. 

In response to the financial strain on healthcare providers, UnitedHealth-owned Optum launched a Temporary Funding Assistance Program in March. This initiative provided over $6 billion in interest-free loans to healthcare providers to address cash flow shortages. As of October, $3.2 billion of the funds had been repaid, reflecting progress in stabilizing the industry. However, some services, such as Clinical Exchange, MedRX, and the Payer Print Communication System, are still undergoing restoration, leaving providers to navigate ongoing challenges. 

The breach also exposed sensitive information of approximately 100 million individuals, making it one of the most significant healthcare data breaches in history. Victims’ full names, email addresses, banking details, and medical claims records were among the data compromised. Change Healthcare’s parent company, UnitedHealth, confirmed that the attackers gained access through stolen credentials used to log into a Citrix portal that lacked multi-factor authentication (MFA). UnitedHealth CEO Andrew Witty testified before Congress, admitting to authorizing a $22 million ransom payment to the attackers. He described the decision as one of the hardest he had ever made, emphasizing the urgent need to minimize further harm to the healthcare system. 

Cybersecurity experts have criticized Change Healthcare for failing to implement basic security protocols, including MFA and robust network segmentation, prior to the attack. The attack’s aftermath has been costly, with remediation expenses exceeding $2 billion as of the most recent UnitedHealth earnings report. Critics have described the company’s lack of preventive measures as “egregious negligence.” Tom Kellermann, SVP of cyber strategy at Contrast Security, highlighted that the company failed to conduct adequate threat hunting or prepare for potential vulnerabilities, despite its critical role in the healthcare ecosystem. 

Beyond the immediate financial impact, the incident has raised broader concerns about the resilience of U.S. healthcare infrastructure to cyberattacks. Experts warn that the sector must adopt stronger cybersecurity measures, including advanced threat detection and incident response planning, to prevent similar disruptions in the future. The restoration of Change Healthcare’s clearinghouse services represents a major step forward, but it also serves as a reminder of the severe consequences of insufficient cybersecurity measures in an increasingly digital healthcare landscape. 

The attack has underscored the urgent need for organizations to prioritize data security, invest in robust safeguards, and build resilience against evolving cyber threats.

Hungarian Defence Agency Hacked: Foreign Hackers Breach IT Systems

 

Foreign hackers recently infiltrated the IT systems of Hungary’s Defence Procurement Agency, a government body responsible for managing the country’s military acquisitions. According to Gergely Gulyas, the chief of staff to Hungarian Prime Minister Viktor Orban, no sensitive military data related to Hungary’s national security or its military structure was compromised during the breach. Speaking at a press briefing, Gulyas confirmed that while some plans and procurement data may have been accessed, nothing that could significantly harm Hungary’s security was made public. The attackers, described as a “hostile foreign, non-state hacker group,” have not been officially identified by name. 

However, Hungarian news outlet Magyar Hang reported that a group known as INC Ransomware claimed responsibility for the breach. According to the outlet, the group accessed, encrypted, and reportedly published some files online, along with screenshots to demonstrate their access. The Hungarian government has refrained from confirming these details, citing an ongoing investigation to assess the breach’s scope and potential impact fully. Hungary, a NATO member state sharing a border with Ukraine, has been increasing its military investments since 2017 under a modernization and rearmament initiative. 

This program has seen the purchase of tanks, helicopters, air defense systems, and the establishment of a domestic military manufacturing industry. Among the notable projects is the production of Lynx infantry fighting vehicles by Germany’s Rheinmetall in Zalaegerszeg, a region in western Hungary. The ongoing conflict in Ukraine, which began with Russia’s 2022 invasion, has further driven Hungary to increase its defense spending. The government recently announced plans to allocate at least 2% of its GDP to military expenditures in 2024. Gulyas assured reporters that Hungary’s most critical military data remains secure. 

The Defence Procurement Agency itself does not handle sensitive information related to military operations or structural details, limiting the potential impact of the breach. The investigation aims to clarify whether the compromised files include any material that could pose broader risks to the nation’s defense strategy. The breach raises concerns about the cybersecurity measures protecting Hungary’s defense systems, particularly given the escalating reliance on advanced technology in modern military infrastructure. With ransomware attacks becoming increasingly sophisticated, governments and agencies globally are facing heightened pressure to bolster their cybersecurity defenses. 

Hungary’s response to this incident will likely involve a combination of intensified cybersecurity protocols and ongoing collaboration with NATO allies to mitigate similar threats in the future. As the investigation continues, the government is expected to release further updates about the breach’s scope and any additional preventive measures being implemented.

2024’s Most Dangerous Malware: A Wake-Up Call for Cybersecurity

 

OpenText, a leader in cybersecurity insights, has released its eagerly awaited “Nastiest Malware of 2024” list, highlighting some of the most destructive and adaptive cyber threats of the year. The list illustrates how ransomware and other malicious software continue to evolve, particularly regarding their impact on critical infrastructure. As cybercriminals refine their tactics, the need to strengthen cybersecurity measures has become increasingly urgent. Organizations around the globe are projected to boost their cybersecurity spending by 14.3% in 2024, raising total investments to over $215 billion, which reflects the magnitude of the challenges posed by these threats. 

LockBit claimed the title of the most dangerous malware of the year. This ransomware-as-a-service (RaaS) entity has demonstrated its ability to evade law enforcement efforts, including those from the FBI. Its ongoing attacks on critical infrastructure showcase its resilience and technical prowess. According to the FBI, LockBit was responsible for 175 reported attacks on essential systems in 2023 alone. The group’s bold ambition to target one million businesses emphasizes its threat level and solidifies its position in the ransomware landscape. 

Akira, a relatively new player, has rapidly gained infamy for its aggressive tactics. This ransomware has been particularly active in industries such as healthcare, manufacturing, and finance, using advanced encryption methods to cause significant disruption. Its retro-inspired branding contrasts sharply with its destructive potential, making it a popular choice among cybercriminal affiliates. 

Meanwhile, RansomHub, which may have connections to the infamous Black Cat (ALPHV) group, has made headlines with its high-profile attacks, including a daring strike on Planned Parenthood that compromised sensitive patient data. 

Other significant threats include Dark Angels, recognized for its precision-targeted attacks on Fortune 50 companies, and Play Ransomware, which takes advantage of vulnerabilities in FortiOS systems and RDP servers. Redline Stealer, while not technically ransomware, this type of threat significantly endangers organizations by focusing on stealing credentials and sensitive information. Each of these threats illustrates how cybercriminals are continually pushing the limits, employing advanced tactics to stay ahead of defenses. 

Muhi Majzoub, OpenText’s EVP and Chief Product Officer, notes that the increase in ransomware targeting critical infrastructure highlights the growing risks to national security and public safety. At the same time, the heightened emphasis on cybersecurity investments is a positive indication that organizations are recognizing these threats. However, the ability of ransomware groups to adapt remains a significant worry, as these criminals continue to leverage new technologies, including artificial intelligence, to create more sophisticated attacks. 

The findings from this year reveal a harsh truth: while progress in cybersecurity is being made, the rapid pace of innovation in malware development poses an ongoing challenge. As companies enhance their vigilance and dedicate more resources to protect vital systems, the battle against cyber threats is far from finished. The changing nature of these attacks requires ongoing adaptation, collaboration, and investment to protect the essential services that support modern society.

How to Prevent a Ransomware Attack and Secure Your Business

 

In today’s world, the threat of cyberattacks is an ever-present concern for businesses of all sizes. The scenario of receiving a call at 4 a.m. informing you that your company has been hit by a ransomware attack is no longer a mere fiction; it’s a reality that has affected several major companies globally. In one such instance, Norsk Hydro, a leading aluminum and renewable energy company, suffered a devastating ransomware attack in 2019, costing the company an estimated $70 million. This incident highlights the vulnerabilities companies face in the digital age and the immense financial and reputational toll a cyberattack can cause. 

Ransomware attacks typically involve hackers encrypting sensitive company data and demanding a hefty sum in exchange for decryption keys. Norsk Hydro chose not to pay the ransom, opting instead to rebuild their systems from scratch. Although this route avoided funding cybercriminals, it proved costly in both time and resources. The question remains, what can be done to prevent such attacks from occurring in the first place? The key to preventing ransomware and other cyber threats lies in building a robust security infrastructure. First and foremost, organizations should implement strict role-based access controls. By defining specific roles for employees and limiting access to sensitive systems based on their responsibilities, businesses can reduce the attack surface. 

For example, financial analysts should not have access to software development repositories, and developers shouldn’t be able to access the HR systems. This limits the number of users who can inadvertently expose critical systems to threats. When employees change roles or leave the company, it’s essential to adjust their access rights to prevent potential exploitation. Additionally, organizations should periodically ask employees whether they still require access to certain systems. If access hasn’t been used for a prolonged period, it should be removed, reducing the risk of attack. Another critical aspect of cybersecurity is the implementation of a zero-trust model. A zero-trust security approach assumes that no one, whether inside or outside the organization, should be trusted by default. 

Every request, whether it comes from a device on the corporate network or a remote one, must be verified. This means using tools like single sign-on (SSO) to authenticate users, as well as device management systems to assess the security of devices trying to access company resources. By making trust contingent on verification, companies can significantly mitigate the chances of a successful attack. Moreover, adopting a zero-trust strategy requires monitoring and controlling which applications employees can run on their devices. Unauthorized software, such as penetration testing tools like Metasploit, should be restricted to only those employees whose roles require them. 

This practice not only improves security but also ensures that employees are using the tools necessary for their tasks, without unnecessary exposure to cyber risks. Finally, no security strategy is complete without regular fire drills and incident response exercises. Preparing for the worst-case scenario means having well-documented procedures and ensuring that every employee knows their role during a crisis. Panic and confusion can worsen the impact of an attack, so rehearsing responses and creating a calm, effective plan can make all the difference. 

 Preventing cyberattacks requires a combination of technical measures, strategic planning, and a proactive security mindset across the entire organization. Business leaders must prioritize cybersecurity just as they would profitability, growth, and other business metrics. By doing so, they will not only protect their data but also ensure a safer future for their company, employees, and customers. The impact of a well-prepared security system is immeasurable and could be the difference between an incident being a minor inconvenience or a catastrophic event.

The Cybersecurity Burnout Crisis: Why CISOs Are Considering Quitting

 

Cybersecurity leaders are facing unprecedented stress as they battle evolving threats, AI-driven cyberattacks, and ransomware. A recent BlackFog study reveals that 93% of CISOs considering leaving their roles cite overwhelming job demands and mental health challenges. Burnout is driven by long hours, a reactive security environment, and the increasing complexity of threats. Organizations must prioritize support for their security teams through flexible work options, mental health resources, and strategic planning to mitigate burnout and retain talent. 

The Rising Pressure on Cybersecurity Leaders The role of the Chief Information Security Officer (CISO) has drastically evolved. They now manage increasingly sophisticated cyberthreats, such as AI-driven attacks and ransomware, in an era where data security is paramount. The workload has increased to unsustainable levels, with 98% of CISOs working beyond contracted hours. The average CISO adds 9 hours a week, and some are clocking over 16 hours extra. This overwork is contributing to widespread burnout, with 25% of CISOs actively considering leaving their roles due to overwhelming stress. The high turnover in this field exacerbates existing security vulnerabilities, as experienced leaders exit while threats grow more sophisticated. 

CISOs face ever-evolving cyberthreats, such as AI-powered attacks, which are particularly concerning for 42% of respondents. These threats use advanced machine learning algorithms to bypass traditional security measures, making them hard to detect and neutralize. Additionally, ransomware is still a major concern, with 37% of CISOs citing it as a significant stressor. The combination of ransomware and data exfiltration forces organizations to defend against attacks on multiple fronts. These heightened risks contribute to a work environment where cybersecurity teams are continually reactive, always “putting out fires” rather than focusing on long-term security strategies. This cycle of incident response leads to burnout and further stress. 

Burnout doesn’t just affect productivity; it also impacts the mental health of CISOs and security teams. According to the study, 45% of security leaders admit to using drugs or alcohol to cope with stress, while 69% report withdrawing from social activities. Although some prioritize physical health—86% allocate time for exercise—many CISOs are still struggling to maintain work-life balance. The emotional toll is immense, with security professionals experiencing the pressure to protect their organizations from increasing cyberthreats while facing a lack of sufficient resources and support. 

To combat the burnout crisis and retain top talent, organizations must rethink their approach to cybersecurity management. Offering flexible work hours, remote work options, and additional mental health resources can alleviate some of the pressure. Companies must also prioritize long-term security planning over constant reactive measures, allowing CISOs the bandwidth to implement proactive strategies. By addressing these critical issues, businesses can protect not only their security infrastructure but also the well-being of the leaders safeguarding it.

Preparing Healthcare for Ransomware Attacks: A 12-Step Approach by Dr. Eric Liederman


Dr. Eric Liederman, CEO of CyberSolutionsMD, emphasizes that healthcare organizations must be prepared for ransomware attacks with a structured approach, describing it as akin to a “12-step program.” He highlights that relying solely on protective measures is insufficient since all protections have the potential to fail. Instead, planning and creating a sense of urgency is key to successfully handling a cyberattack. 

According to Liederman, organizations should anticipate losing access to critical systems and have a strategic recovery plan in place. One of the most important components of such a plan is designating roles and responsibilities for the organization’s response. During an attack, the Chief Information Security Officer (CISO) essentially takes on the role of CEO, dictating the course of action for the entire organization. Liederman says the CISO must tell people which systems are still usable and what must be shut down. 

The CEO, in this situation, plays a supporting role, asking what’s possible and what needs to be done to protect operations. A significant misconception Liederman has observed is the assumption that analog systems like phones and fax machines will continue functioning during a ransomware attack. Often, these systems rely on the same infrastructure as other compromised technology. For example, phone systems that seem analog still resolve to an IP address, which means they could be rendered useless along with other internet-based systems. 

Even fax machines, commonly thought of as a fail-safe, may only function as copiers in these scenarios. Liederman strongly advises healthcare institutions to conduct thorough drills that simulate these kinds of disruptions, enabling clinical and IT staff to practice workarounds for potentially critical outages. This level of preparation ensures that teams can still deliver care and operate essential systems even when technological resources are down for days or weeks. 

In terms of system recovery, Liederman encourages organizations to plan for bringing devices back online securely. While the need to restore services quickly is essential to maintaining operations, the process must be carefully managed to avoid reinfection by the ransomware or other vulnerabilities. Given his extensive experience, which includes almost two decades at Kaiser Permanente, Liederman advocates for resilient healthcare IT infrastructures that focus on readiness. This proactive approach allows healthcare organizations to mitigate the potential impacts of cyberattacks, ensuring that patient care can continue even in worst-case scenarios.

Columbus Faces Scrutiny for Handling of Ransomware Attack and Lawsuit Against IT Consultant

 

In July, Columbus, Ohio, experienced a ransomware attack, which initially appeared to be a typical breach. However, the city’s unusual response sparked concern among cybersecurity experts and legal professionals. IT consultant David Leroy Ross, also known as Connor Goodwolf, uncovered a significant breach exposing sensitive data from various city databases, including arrest records, domestic violence cases, and personal information. 

This attack, carried out by the Rhysida Group, affected the city, police, and prosecutor’s office, with some databases going back to 1999. Goodwolf, whose expertise involves monitoring dark web activities, discovered that over three terabytes of data had been stolen. Among the exposed data were personal identifiable information, protected health information, and social security numbers. Goodwolf expressed particular concern over the exposure of sensitive information involving minors and domestic violence victims, emphasizing that they were now victimized a second time. 

Despite the serious implications, the city’s response appeared to downplay the breach. At a press conference in mid-August, Columbus Mayor Andrew Ginther claimed that the stolen data was encrypted or corrupted, making it largely unusable. Goodwolf, however, contradicted this statement, revealing that the data he found was intact and usable. When he attempted to notify city officials, he was met with resistance and a lack of cooperation. As a result, Goodwolf turned to the media, which led the city of Columbus to file a lawsuit and secure a temporary restraining order against him. The lawsuit, intended to prevent the further dissemination of sensitive information, raised concerns in the cybersecurity community. 

Legal experts pointed out that such lawsuits against data security researchers are uncommon and could have broader implications. Raymond Ku, a professor of law, noted that lawsuits against researchers typically arise when the disclosure of a vulnerability puts others at risk. However, cybersecurity professionals, such as Kyle Hanslovan, CEO of Huntress, argued that Goodwolf was acting as a responsible researcher. Hanslovan warned that this approach could set a dangerous precedent, silencing individuals who work to expose breaches. The city defended its actions, stating that it sought to prevent the release of confidential information, including undercover police identities. Although the restraining order expired, Columbus continues its civil lawsuit against Goodwolf, seeking up to $25,000 in damages. 

As Columbus works to recover from the attack, the broader implications of its actions toward Goodwolf remain a point of contention. Experts argue that the case highlights the need for a legal framework that balances the protection of sensitive information with the role of security researchers in revealing vulnerabilities. As Columbus strives to position itself as a tech hub, this legal battle could affect its reputation and relationships within the tech industry.

ESXi Servers are Targeted by Linux-Based Akira Ransomware

 


As part of a ransomware operation called Akira, VMware ESXi virtual machines have been encrypted using a Linux encryption tool. This is to block access to the virtual machines. The attack comes after the company targeted Windows systems for a couple of months. 

To encrypt VMware ESXi virtual machines in double-extortion attacks against companies worldwide, the Akira ransomware operations use a Linux encryptor to encrypt VMware ESXi virtual machines controlled by VMware. 

There has been a recent expansion of the Akira ransomware and it now targets VMware ESXi virtual machines using a Linux encryptor. It is because of this adaptation that Akira can now attack companies across the globe. 

This ransomware virus, Akira, was found in March 2023. As the most recent addition to the ransomware landscape, it is relatively less well-known. 

In the short time that Akira ransomware has been in operation, it has been confirmed that 45 organizations have been affected. Most of the targets are based in the U.S. Organizations affected range from childcare centers to large financial institutions but all have been affected. 

The threat actors are engaged in double extortion attacks against their victims, demanding several million dollars and stealing data from breached networks, encrypting files, and encrypting the data until they reach the point of demanding payouts.

In addition to asset managers, the gang's blog lists several victims of the gang's crimes. Akira will encrypt the files of an organization after an attack has been launched, appending the name of the encrypted files to the file names. The desktop screen will display a ransom note, explaining in a condescending tone that it is the quickest way back to the state where the company functions normally if you pay the ransom. 

The Development Bank of Southern Africa and London Capital Group are completely aware of the damage they have caused. There are many US-based companies on the gang's black web blog. 

This computer virus, known as Akira, uses double extortion techniques to pressure its victims into paying a ransom. This means that Akira copies the data before encrypting it to make sure the information can not be released, as well as selling the description key, and using these techniques to force a company into paying the ransom. 

In some cases, the ransoms amount to more than a million dollars, while in others it is less. It has focused on professional services, education, manufacturing, and research and development so far.

In sectors as diverse as education and finance, the threat of ransomware has disrupted corporate networks and encrypted stolen data from breached networks. These compromised files are marked with the extension .akira, which signifies compromise. 

It is important to note that, after the Akira ransomware has been activated, many different file extensions and names will become encrypted, as well as renamed files with the .akira extension. There will also be a ransom note titled akira_readme.txt left in each folder on the encrypted device. 

It is possible to customize how Akira works on Linux, which includes specifying the percentage of data that will be encrypted on each file, which allows threat actors to better customize their attacks. The propensity of this version of Akira to skip folders and files that are usually associated with Windows seems to indicate that it has been ported from the Windows version of the game.

Despite Akira's increasing scope, the fact that the threat now faces organizations around the world illustrates the urgency of action. Sadly, ransomware groups are increasingly expanding their operations to include Linux platforms as well. Many of them are leveraging readily available tools to do so due to the trend toward expanding their operations. To maximize their profits, they have turned this strategy into a simple and lucrative one. 

Among the most notable ransomware operations, some of which predominantly target VMware ESXi servers with their ransomware encryptors, include Royal, Black Basta, LockBit, BlackMatter, AvosLocker, HelloKitty, RansomEXX, and Hive. These operations use Linux-based encryption methods. 

Spreads Rapidly, is Widely Popular, and is Unsecured 

During a ransomware attack, servers are popular due to their ability to spread ransomware rapidly. Hackers need only one run to launch the ransomware attack, which means the ransomware attack becomes extremely fast for the first time in history. ESXi servers have gained popularity in the enterprise world, as they are among the most widely used hypervisors on the planet. Lastly, the devices do not have any security solutions installed on them, which leads to a lack of security. CrowdStrike published a report previously that focused on the fact that antivirus software simply isn't supported by the manufacturer. 

During the weekend of February 2-6, ESXi servers were targeted by thousands of attacks taking place simultaneously. The attackers were able to exploit an outdated vulnerability that had existed two years ago. As a result, good cyber security for servers is very important because research can take a long time and is not always easy. A problem that had not yet been exploited massively had been discovered by Mandiant in 2022, but the problem was still unknown.
