Federal Agencies Worldwide Hunt for Black Basta Ransomware Leader


International operation to catch Ransomware leader 

International law enforcement agencies have increased their search for individuals linked to the Black Basta ransomware campaign. Agencies confirmed that the suspected leader of the Russia-based Ransomware-as-a-service (RaaS) group has been put in the EU’s and Interpol’s Most Wanted list and Red Notice respectively. German and Ukrainian officials have found two more suspects working from Ukraine. 

As per the notice, German Federal Criminal Police (BKA) and Ukrainian National Police collaborated to find members of a global hacking group linked with Russia. 

About the operation 

The agencies found two Ukrainians who had specific roles in the criminal structure of Black Basta Ransomware. Officials named the gang’s alleged organizer as Oleg Evgenievich Nefedov from Russia. He is wanted internationally. German law enforcement agencies are after him because of “extortion in an especially serious case, formation and leadership of a criminal organization, and other criminal offenses.”

According to German prosecutors, Nefedov was the ringleader and primary decision-maker of the group that created and oversaw the Black Basta ransomware. under several aliases, such as tramp, tr, AA, Kurva, Washingt0n, and S.Jimmi. He is thought to have created and established the malware known as Black Basta. 

The Ukrainian National Police described how the German BKA collaborated with domestic cyber police officers and investigators from the Main Investigative Department, guided by the Office of the Prosecutor General's Cyber Department, to interfere with the group's operations.

The suspects

Two individuals operating in Ukraine were found to be carrying out technical tasks necessary for ransomware attacks as part of the international investigation. Investigators claim that these people were experts at creating ransomware campaigns and breaking into secured systems. They used specialized software to extract passwords from business computer systems, operating as so-called "hash crackers." 

Following the acquisition of employee credentials, the suspects allegedly increased their control over corporate environments, raised the privileges of hacked accounts, and gained unauthorized access to internal company networks.

Authorities claimed that after gaining access, malware intended to encrypt files was installed, sensitive data was stolen, and vital systems were compromised. The suspects' homes in the Ivano-Frankivsk and Lviv regions were searched with permission from the court. Digital storage devices and cryptocurrency assets were among the evidence of illicit activity that police confiscated during these operations.

European Authorities Identify Black Basta Suspects as Ransomware Group Collapses

 

Two Ukrainians are now under suspicion of aiding Black Basta, a ransomware network tied to Russia, after joint work by police units in Ukraine and Germany - this step adds pressure on the hacking group’s operations. The man believed to lead the gang, Oleg Evgenievich Nefedov, aged thirty-five and holding Russian citizenship, appears on key global alerts: one issued by the EU, another by INTERPOL. Though named, he remains at large. 

A Ukrainian cybercrime unit identified two people who handled technical tasks for a ransomware network, focusing on breaking into secured systems. These individuals worked by uncovering encrypted passwords through dedicated tools. Their job was to unlock access codes so others could move deeper. With those login details, associates entered company servers without permission. They installed malicious encryption programs afterward. Victims then faced demands for money before files would be released. 

Finding hidden data drives inside apartments across Ivano-Frankivsk and Lviv opened a path toward tracking illegal transactions. Though police stayed silent on custody details, they emphasized digital trails now feed directly into active probes. 

Emerging in April 2022, Black Basta quickly rose as a leading ransomware force worldwide. Over 500 businesses in North America, Europe, and Australia faced its attacks, bringing in hundreds of millions through crypto ransoms. Instead of acting alone, the group used a service-based approach, pulling in partners who received profit cuts for launching assaults on their behalf. 

Early in 2025, internal chat records from Black Basta were made public, showing how the group operated and naming those involved. Nefedov emerged as the central figure behind the network; his known aliases included Tramp, Trump, GG, and AA. Evidence within the files suggested ties between him and high-level individuals in Russian politics. Links to state security bodies like the FSB and GRU appeared in some messages. 

Such affiliations might explain why legal action against him never moved forward. The disclosure offered rare insight into an otherwise hidden criminal ecosystem. A report from June 2024 noted a short detention of Nefedov in Yerevan, Armenia; authorities let him go afterward. Although listed internationally as a fugitive, where he is now has not been confirmed - evidence suggests Russia may be harboring him. 

Some researchers connect Nefedov to Conti, a well-known ransomware outfit that ended in 2022. When Conti broke apart, new groups appeared - Black Basta, BlackByte, and KaraKurt among them. Following the split, ex-Conti members moved into different ransomware efforts, though certain ones eventually stopped operating. A different analysis by Analyst1 showed Black Basta made frequent use of Media Land - an internet host blacklisted by U.S., British, and Australian governments in late 2025 due to its resistance to takedown requests. 

According to officials in Germany, Nefedov was responsible for choosing victims, bringing in new people, handling payment talks after attacks, then splitting the money taken with others involved. After the leaks, activity from Black Basta's systems stopped. Its public leak page vanished by February. 

Still, security analysts note such criminal networks frequently reappear under different names or combine forces elsewhere. Data collected by ReliaQuest together with Trend Micro points toward ex-members possibly joining CACTUS. A sharp increase in victims claimed by CACTUS emerged right when Black Basta faded.

Black Basta Under Pressure After Ukraine Germany Enforcement Operation


 

Investigators say the Black Basta ransomware campaign left a trail of disruption that extended across Europe and beyond, impacting everything from hospital wards to industrial production lines that were abruptly halted, resulting in a temporary ban of internet and phone use.

Prosecutors from the German Federal Ministry of Justice, along with international law enforcement partners, now believe that the trail of this extortion, the most damaging in recent years, can be traced back to one individual who they describe as the driving force behind one of these operations. 

There has been an investigation into whether Oleg Nefedov was the architect and operational leader of the Black Basta group. Authorities have identified him as a Russian national. 

Authorities accuse him of coordinating a massive ransomware campaign against companies and public institutions across multiple continents by forming and leading an overseas criminal organization.

There is a suspicion among investigators that Nefedov was responsible for leading the organization's core activities, including selecting targets, recruiting affiliates, orchestrating intrusions, and negotiating ransoms, while the proceeds of the transactions were laundered via cryptocurrency wallets and distributed among all participants in the scheme.

Black Basta was also analyzed from an online alias perspective and suspected ties to a now-defunct ransomware collective named Conti. This reinforces the assessment that Black Basta arose from an advanced and interconnected cybercrime ecosystem that has matured over many years. 

Officials from the Federal Republic of Germany have confirmed that Nefedov still resides in Russia and that he has been placed on Interpol's international wanted list, an indication that European authorities have intensified their efforts to identify and pursue the individuals behind cyber extortion committed in large scale industrial scales. 

The Federal Criminal Police Office of Germany has confirmed that Oleg Nefedov, a 36-year-old Russian national suspected of leading the Black Basta ransomware group, is one of the suspected leaders of the ransomware. He is charged with forming criminal organizations abroad, orchestrating large-scale extortion crimes, and committing related cyber crimes. 

A central coordinator was alleged by investigators to be Nefedov. During his time at the group, Nefedov selected targets, recruited and managed members, assigned operational roles, negotiated ransom demands, and distributed extorted proceeds, which were usually paid in cryptocurrency, according to the investigation. 

There were several aliases he operated under on the internet-including tramp, tr, gg, kurva, AA, Washingt0n, and S.Jimmi-and authorities say he may have maintained a connection to the now-defunct Conti ransomware group. 

According to German authorities, Nefedov is believed to be in Russia at the moment, though his exact location remains unclear. Interpol has also added him to a global wanted list. In recent months, the investigation has been further strengthened by numerous disclosures and enforcement actions that have heightened the investigation. 

A leaked internal chat log attributed to Black Basta, which gave rare insights into the group's organization, operations, and communications, as well as exposing identifying information about the individuals involved. This information provided an insight into the organization's inner workings and daily operations. 

According to cybersecurity researchers, many of the Black Basta members previously operated within criminal networks that were closely linked to the Conti and Ryuk ransomware strains, as well as the TrickBot banking trojan — operations that have led Western governments to identify and sanction more than a dozen individuals for their involvement in such attacks. 

According to researchers and investigators, Black Basta is the result of the collapse of Conti, a ransomware operation which fragmented into smaller, semi-autonomous cells after it shut down. In a recent study published by the International Security Agency, Black Basta has been widely interpreted as a rebranding of the former Conti infrastructure, with many of those splinter groups either embedding themselves into existing ransomware schemes or controlling existing operations. 

It has been demonstrated that this view has been reinforced by a review of leaked internal communications by Trellix researchers. According to those who reviewed the Black Basta chat logs, GG and Chuck were exchanging emails about a purported $10 million reward for information about an individual, referred to as “tr” or “-amp,” an individual which researchers believe corresponds to a bounty offered by the U.S. Government for information that will lead to the identification of key Conti figures, including Tramp, the hacker. 

Additionally, Trellix researchers found that within the leaked conversations, GG was identified as Tramp, who had been regarded as Conti's leader for some time, by a participant called "bio," sometimes known as "pumba," a figure who was previously connected to the Conti organization. 

These findings echo those released earlier in February 2022, when a researcher revealed Conti's internal chats in the aftermath of the Russian invasion of Ukraine, revealing internal dynamics and explicitly referring to Tramp as leader of the group. 

It is well-known that such leaks have long been a source of attribution efforts within the cybersecurity industry, but German authorities say that their current case rests on evidence gathered through intelligence and investigation on the German side. 

Oleg Nefedov has been identified formally as the head of the Black Basta ransomware group by Europol, and the Interpol red notice database has been updated with his name. This is a crucial step in the international effort to enquire about the group's activities, marking a decisive step in the effort to enshrine accountability for the group. 

The data breach is the result of an attack on more than 500 organizations across North America, Europe, and Australia by means of Black Basta's ransomware-as-a-service model, which was active since April 2022 and caused hundreds of millions of dollars in damage in the process.

Two suspects in western Ukraine, which were allegedly acting as hash crackers in order to help facilitate network intrusions, data theft, and ransomware deployment, were also announced by German authorities. The police seized digital devices and cryptocurrency during raids that are related to the incident, and are currently conducting forensic analysis of the evidence. 

Official figures underscore the scale of the damage attributed to the group. An official press release from the German authorities stated that documented Black Basta attacks have caused prolonged operational disruptions at over 100 companies in Germany, as well as over 700 organizations worldwide, including hospitals, public institutions, and government agencies. 

In Germany, it is estimated that losses will exceed 20 million euros in the next few years. Research conducted in December 2023 by blockchain analytics firm Elliptic and Corvus Insurance found that over the course of the past four years, the group accumulates at least $107 million in Bitcoin ransom payments, which has been determined to be paid by over 329 victims in 31 countries across the world. 

A detailed analysis of blockchain transactions also revealed a clear financial and operational link between Black Basta and Conti, which supported the conclusions of law enforcement that this syndicate grew out of a well-established, interconnected cybercrime ecosystem that was well-established and interconnected. 

In light of the scope and selectivity of Black Basta's operations, it is evident why it has been a top priority for law enforcement and security researchers to investigate. A number of victims have been confirmed, including Rheinmetall, Hyundai, BT Group, Ascension, ABB, the American Dental Association, U.K.-based outsourcing company Capita, the Toronto Public Library, the Yellow Pages Canada, and others. 

These victims include German defense contractor Rheinmetall, Hyundai's European division, BT Group, as well as the United States healthcare provider Ascension. According to the researchers, the group did not operate in an indiscriminate manner, but applied a targeted strategy based on geography, industry, and organizational revenue, while also closely tracking geopolitical developments in order to reduce the likelihood of retaliation from law enforcement agencies. 

A ransomware operation known as Black Basta, which is characterized by a focus on large, high-revenue organizations with the ability to pay large ransoms, was known to be targeting large, high-revenue organizations. Based on internal communications, it appears that entities in both the United States and Germany were the most likely to pay a ransom. 

There are 57 percent of victims in the United States who had reported a leak between April 2022 and January 2025, with Germany accounting for 12 percent, while additional victims were observed throughout Europe, Asia Pacific and the Americas as well. 

Accordingly, that assessment is reflected in activity observed on the group's leak site. Several leaks of internal chats in the group have introduced rare insights into the group's internal structure, its financial management, and its extortion practices, which have strengthened efforts to identify key actors and disrupt their operations by exposing real-world names and financial transactions. 

Despite the fact that Black Basta’s data leak site is currently offline, analysts warn that the group still has the resources and incentives to re-emerge, either by adopting a new name or partnering with other ransomware crews, illustrating how authorities continue to face challenges in dismantling entrenched cybercrime networks rather than simply disrupting them, even when the site is offline. 

Together, these findings present a detailed portrayal of a ransomware operation that developed out of a fractured but resilient cybercrime ecosystem into a global enterprise that has far-reaching consequences. Having identified an alleged leader along with financial tracing, leaking internal communications, and coordinated international enforcement, German authorities state that the investigation has matured—with an emphasis not only on disruption, but also on attribution and accountability for ransomware. 

It should be noted that while law enforcement actions have slowed Black Basta's visible activities, experts and officials agree that dismantling such networks will take years, especially when key figures are believed to be operating in jurisdictions that are beyond the reach of law enforcement officials. 

In addition to demonstrating the extent of the harm caused by ransomware campaigns, the case also highlights the growing determination of governments to pursue those responsible, even through the broader cybercrime landscape continues to evolve, fragment, and resurface.

Hackers Tricking Employees with Fake IT Calls and Email Floods in New Ransomware Scam

 


A growing number of cyberattacks are being carried out by a group linked to the 3AM ransomware. These attackers are using a combination of spam emails and fake phone calls pretending to be a company’s tech support team. Their goal is to fool employees into giving them access to internal systems.

This method, which has been seen in past cyber incidents involving other groups like Black Basta and FIN7, is becoming more widespread due to how effective it is. Cybersecurity company Sophos has confirmed at least 55 attacks using this approach between November 2024 and January 2025. These incidents appear to come from two different hacker groups following similar tactics.

In one recent case during early 2025, the attackers targeted a company using a slightly different method than before. Instead of pretending to be tech support over Microsoft Teams, they called an employee using a fake caller ID that showed the company’s actual IT department number. The call took place while the employee’s inbox was being flooded with dozens of spam emails in just minutes — a technique known as email bombing.

During the call, the attacker claimed the employee's device had security issues and asked them to open Microsoft’s Quick Assist tool. This is a real remote help feature that allows another person to take control of the screen. Trusting the caller, the employee followed instructions and unknowingly handed over access to the attacker.

Once inside, the hacker downloaded a dangerous file disguised as a support tool. Inside the file were harmful components including a backdoor, a virtual machine emulator (QEMU), and an old Windows system image. These tools allowed the attacker to hide their presence and avoid detection by using virtual machines to move through the network.

The hacker then used tools like PowerShell and WMIC to explore the system, created a new admin account, installed a remote support tool called XEOXRemote, and gained control of a domain-level account. Although Sophos security software stopped the ransomware from spreading and blocked attempts to shut down protections, the hacker managed to steal 868 GB of company data. This data was sent to cloud storage using a syncing tool called GoodSync.

The full attack lasted around nine days. The majority of the data theft happened in the first three days before the attackers were cut off from further access.

To protect against such attacks, Sophos suggests reviewing admin accounts for weaknesses, using security tools that can spot unusual uses of trusted programs, and setting strict rules for running scripts. Most importantly, companies should train employees to recognize signs of fake support calls and suspicious emails, as these scams depend on fooling people — not just machines.

The 3AM ransomware group is relatively new, first spotted in late 2023, but appears to have links with well-known cybercrime networks like Conti and Royal.


Black Basta: Exposing the Ransomware Outfit Through Leaked Chat Logs

 

The cybersecurity sector experienced an extraordinary breach in February 2025 that revealed the inner workings of the well-known ransomware gang Black Basta. 

Trustwave SpiderLabs researchers have now taken an in-depth look at the disclosed contents, which explain how the gang thinks and operates, including discussions about tactics and the effectiveness of various attack tools. Even going so far as to debate the ethical and legal implications of targeting Ascension Health. 

The messages were initially posted to MEGA before being reuploaded straight to Telegram on February 11 by the online identity ExploitWhispers. The JSON-based dataset contained over 190,000 messages allegedly sent by group members between September 18, 2023 and September 28, 2024. 

This data dump provides rare insight into the group's infrastructure, tactics, and internal decision-making procedures, providing obvious links to the infamous Conti leaks of 2022. The leak does not provide every information about the group's inner workings, but it does provide a rare glimpse inside one of the most financially successful ransomware organisations in recent years. 

The dataset reveals Black Basta's internal workflows, decision-making processes, and team dynamics, providing an unfiltered view of how one of the most active ransomware gangs functions behind the scenes, with parallels to the infamous Conti leaks. Black Basta has been operating since 2022. 

The outfit normally keeps a low profile while carrying out its operations, which target organisations in a variety of sectors and demand millions in ransom payments. The messages demonstrate members' remarkable autonomy and ingenuity in adjusting fast to changing security situations. The leak revealed Black Basta's reliance on social engineering tactics. While traditional phishing efforts are still common, they can take a more personable approach in some cases. 

The chat logs provide greater insight into Black Basta's strategic approach to vulnerability exploitation. The group actively seeks common and unique vulnerabilities, acquiring zero-day exploits to gain a competitive advantage. 

Its weaponization policy reveals a deliberate effort to increase the impact of its attacks, with Cobalt Strike frequently deployed for command and control operations. Notably, Black Basta created a custom proxy architecture dubbed "Coba PROXY" to manage massive amounts of C2 traffic, which improved both stealth and resilience. Beyond its technological expertise, the leak provides insight into Black Basta's negotiation strategies. 

The gang uses aggressive l and psychologically manipulative tactics to coerce victims into paying ransoms. Strategic delays and coercive rhetoric are standard tactics used to extract the maximum financial return. Even more alarming is its growth into previously off-limits targets, such as CIS-based financial institutions.

While the immediate impact of the breach is unknown, the disclosure of Black Basta's inner workings provides a unique chance for cybersecurity specialists to adapt and respond. Understanding its methodology promotes the creation of more effective defensive strategies, hence increasing resilience to future ransomware assaults.

Black Basta Hackers Use New Tool to Break Weak Passwords on Remote Systems

 



A cybercriminal group called Black Basta has built a new tool that helps them break into remote systems like VPNs and firewalls by guessing weak passwords. This tool allows them to easily target companies and demand ransom.

According to cybersecurity experts, the tool— named BRUTED, automatically scans the internet to find systems that might be easy to hack. It focuses on popular VPN and firewall services from companies like Cisco, Fortinet, Palo Alto, and others. It also attacks systems used for remote desktop access.

The tool gathers information like IP addresses, website subdomains, and security certificates to help guess passwords specific to each organization. It then sends fake login requests that look like they’re from a real user or device, making it harder to detect.

Since BRUTED runs automatically, it helps hackers attack many targets quickly. This increases their chances of breaking in and earning money from ransomware attacks.

Experts warn that many companies still rely on simple or repeated passwords, which makes their systems easy to hack. Sometimes, attackers use leaked or default passwords that organizations forget to change.

This poor password management exposes businesses to big risks. In fact, weak passwords might have also caused a leak in Black Basta’s own data when a hacker broke into a Russian bank and exposed the gang’s private chats.

Black Basta is known for targeting important industries like healthcare and manufacturing, where even a small disruption can cause major losses. These industries are more likely to pay ransom to avoid shutdowns.

Security experts are urging businesses to act fast—use strong and unique passwords, change default settings, run regular security checks, and train employees about password safety.

Good password habits can help prevent such attacks and protect important systems from hackers like Black Basta.


Ransomware Hackers Develop Advanced Tool for VPN Breaches

 


In the Black Basta ransomware group, an automated brute force attack tool referred to as BRUTED has been developed to target and compromise edge networking devices such as firewalls and VPNs, as well as other edge networking devices. By using this sophisticated tool, they can efficiently breach vulnerable internet-facing endpoints, making them able to scale ransomware attacks considerably better than ever before. 

A researcher at EclecticIQ identified the presence of BRUTED when she analyzed internal chat logs related to the ransomware gang, and she found that BRUTED exists. These logs were used to reveal insight into the tool's deployment and revealed that Black Basta has been employing BRUTED to conduct credential-stuffing and brute-force attacks since 2023 against a variety of remote access software programs. This cyber threat has been targeting a wide variety of systems, including SonicWall NetExtender, Palo Alto GlobalProtect, and Citrix NetScaler, highlighting the broad scope of the threat. 

It is Black Basta's intention to improve its operational efficiency by automating brute-force attacks, which in turn allows it to exploit critical infrastructure security vulnerabilities more systematically. As a result of the discovery of BRUTED, organizations relying on internet-connected security solutions are at an even higher risk of cybercrime, as the evolving tactics and sophistication of ransomware groups are becoming more complex. 

The Black Basta ransomware operation has developed an automated brute-force framework known as BRUTED, which has been designed specifically to compromise edge networking devices, such as firewalls and virtual private network access points. As a result of this advanced framework, the group can gain early access to targeted networks, which facilitates large-scale ransomware attacks on vulnerable, internet-connected endpoints, which will lead to a successful attack. 

A recently published study by Arda Büyükkaya, a cyber threat intelligence analyst at EclecticIQ, confirms that the Black Basta ransomware group is using a previously unidentified brute-force framework for stealing data. Known as BRUTED, this framework is specifically crafted to automate the process of compromising enterprise VPNs and firewalls, thus enhancing the group's ability to gain unauthorized access to corporate networks, which is significantly enhanced. 

Multiple reports have emerged throughout 2024 detailing the extensive use of brute-force attacks against these devices and password spray. It is still unclear how these incidents are linked to BRUTED or other threat actor operations, although the issue is still under investigation. This tool has been developed to highlight the increasing sophistication of ransomware tactics and the increasing risk organizations face when relying on internet-connected security infrastructure as part of their security measures. 

A thorough analysis of Büyükkaya's source code has proven that the tool's primary function consists of snooping across the internet and credential stuffing attacks, to attack edge network devices. It has been widely used within corporate environments to implement firewalls and VPN solutions. By its log-naming conventions, BRUTED is referred to as the bruised tool, and researchers at EclecticIQ have concluded that it is used by Black Basta to perform large-scale credential-stuffing attacks. This group gains an initial foothold by exploiting weak or reused credentials, which allows them to move from compromised networks to other compromised ones, and ultimately install ransomware. 

It is also BRUTED's responsibility to assist affiliates, who are responsible for performing initial access operations in ransomware campaigns, as well as to enhance the group's operational efficiency. As the framework automates and scales attacks, it can widen the victim pool and accelerate the monetization process, thus increasing the efficiency of ransomware operations. As a result of this discovery, cybercriminals have become increasingly sophisticated in their tactics, which highlights the need for robust security measures to protect against them. 

Arda Büyükkaya explained that the BRUTED framework will enable Black Basta affiliates to automate and scale their attacks to significantly increase the number of victims they can target, as well as boost their monetization efforts to continue operating ransomware. As a result of the emergence of this brute-forcing tool, edge devices are demonstrating their ongoing vulnerability, especially in light of persistent warnings from private cybersecurity firms and government agencies regarding increased threats targeting VPN services. Even though these advisories have been issued, it remains a lucrative attack vector for cybercriminals to hack passwords for firewalls and virtual private networks (VPNs). 

According to the Qualys team, a blog post a while back highlighted the fact that Black Basta has been using default VPN credentials, brute force techniques involving stolen credentials, and other forms of access to gain initial access to their systems. In this report, the manager of vulnerability research at Qualys Threat Research Unit and a co-author of the report asserted that weak passwords for VPNs and other services that are open to the public continue to pose a significant security risk to organizations. 

Furthermore, Abbasi emphasized that several leaked Black Basta chat logs contained simple or predictable credentials, demonstrating the persistent vulnerabilities that threat actors exploit to infiltrate corporate networks. By implementing the BRUTED framework, threat actors can streamline their ransomware operations, as it enables them to infiltrate multiple networks at the same time with as little effort as possible.

As a result of this automation, cybercriminals have access to greater monetization opportunities, which allows them to scale their attacks more efficiently. The risks posed by such tools must be mitigated by the adoption of strong cybersecurity practices. To protect against these risks, organizations must enforce unique passwords for all edge devices and VPNs. Further, multi-factor authentication (MFA) is an essential component of any security system because it adds another layer of protection that prevents unauthorized access, even when credentials are compromised. To identify potential threats, continuous network monitoring is also crucial. 

Security teams should keep an eye on authentication attempts coming from unfamiliar locations and flag high volumes of failures to log in as an indicator of brute force attacks. Several measures can be implemented to reduce the effectiveness of credential-stuffing techniques, such as rate-limiting measures and account-locking policies. As a result of the growing threat of BRUTED, EclecticIQ has provided a list of IP addresses and domains associated with the framework to the public in response. 

Indicators such as these can be used to update firewall rules so that requests from known malicious infrastructure will be blocked effectively while limiting the tool's reach. BRUTED does not exploit software vulnerabilities to gain access to network edge devices, but maintaining up-to-date security patches remains an important part of cybersecurity. Regularly applying the latest patches ensures that potential vulnerabilities in the network security systems are addressed, thus strengthening the overall resilience of the network security systems.

Persistent Increase in Ransomware Attacks Raises Global Security Concerns

 


It was concluded that in the first five weeks of 2025, there was a significant increase in ransomware attacks targeted at the United States, marking a nearly 150% increase compared to the first five weeks of 2024. Based on a series of high-profile incidents in which certain organisations decided to pay ransoms to avoid detection, cybercriminals have inadvertently increased their interest in the U.S. and made the country a more attractive target for cybercriminals. 

Consequently, this factor is largely responsible for the increase in ransomware activity in the last few months, as successful ransom payments have likely incentivized other ransomware attacks. In the past year, despite fluctuations in the most active ransomware groups and specific timeframes, the frequency of ransomware incidents in the United States has substantially increased. There has been a significant rise in ransomware incidents since the fall of 2024, and a steady increase has continued into the new year. Security firm NCC Group reports 590 new ransomware victims in January, a 3% increase from the previous month, which already set a record for that period. 

The threat intelligence company Cyble has also identified 518 new victims in January, and this number has increased to 599 within the past 27 days. Approximately two-thirds of the attacks were conducted against organizations located in the United States. Additionally, other cybersecurity monitoring organizations have noted a rise in ransomware incidents over the past two months. The difference in victim counts between cybersecurity firms may be attributed to the difference in methodologies, in particular whether victims of previously compromised cybersecurity systems who have just been revealed should be classified as new victims. 

However, despite these discrepancies, industry experts all agree that ransomware activity has increased in recent months. There are several notable ransomware groups responsible for driving this increase, among which RansomHub, Play, and Akira stand out as prominent threat actors. As a result of their increased activity, organizations across the globe are facing increasing cybersecurity challenges as a result of their increased activities. There is still a persistent threat of ransomware, however, individual ransomware groups emerge and dissipate frequently. 

Some of these groups, such as Black Basta, are now in decline or are nearing obsolescence, while others are suffering disruption due to law enforcement intervention, as LockBit appears to be the case. Groups that suffer from internal conflict, often driven by financial disputes, are prone to collapse. For instance, Alphv, also known as BlackCat, was notorious for conducting an exit scam 12 months ago, retaining the entire $22 million ransom paid by UnitedHealth Group following the Change Healthcare hack, rather than sharing it with the affiliate that carried out the scam. 

Although some ransomware groups have disbanded at the end of last year, the landscape of ransomware continues to be highly dynamic, with new actors continuously emerging. In many instances, these "new" actors are not merely rebranded entities, but individuals already entrenched in the cybercrime ecosystem himself. A significant percentage of these attacks are the result of affiliates, threat actors who work with several ransomware operations. Regardless of which specific group name they operate under, affiliations are responsible for a significant portion of these attacks, according to cybersecurity firm BlackFog. In 2024, 48 new ransomware groups surfaced. 

There are four victims mentioned publicly on RunSomeWare's data leak sites, whereas Linkc only has one victim posted on its data leak site, as reported by threat intelligence firm Cyble. It is unclear how long these emerging groups will survive in this business. In December 2024, Anubis, a Russian-speaking ransomware group that first became active, appears to be the work of former ransomware affiliates, as indicated by the sophistication of its tactics. 

Kela reports that Anubis maintains a presence on cybercrime forums like RAMP and XSS, which reinforces its network within the cybercriminal underground by ensuring it maintains its visibility on these forums. In addition to offering a range of illicit services, this group also operates a traditional ransomware-as-a-service model, where affiliates are rewarded with 80% of the ransom money collected from victims they infect. 

As well as targeting Windows, Linux, network-attached storage (NAS), and ESXi environments, Anubis' ransomware can also be used to spread the virus. In addition, the group maintains a data leak blog based on Tor, where so far only a few people have been listed. The Anubis ransomware operation offers two distinct services in addition to conventional ransomware. In the first case, participants receive 60% of the revenue extorted from victims using stolen data, based on the data-ransom-as-a-service model. If the stolen data are unpublished, have been obtained within the past six months, and considered valuable enough for public exposure, they are eligible for this program. By releasing a press release and notifying local data privacy regulators about the breach, Anubis claims to amplify pressure on victims. 

It is the second offering of Anubis that targets initial access brokers, who facilitate cyber intrusions by selling credentials to compromised networks to gain access to them. Under Anubis' model, the IABs become eligible for 50% of all ransoms demanded by victims whose credentials they have supplied. A specific set of eligibility criteria applies, including being a citizen of the United States, Canada, Europe, or Australia, not having been targeted by another ransomware group within the last 12 months, and not being employed by the government, the educational system, or any non-profit organization. 

Ransomware groups are long collaborating with initial access brokers and have often paid a premium for exclusive access to compromised networks, but the healthcare industry remains a viable target. Cybercrime brokers are increasingly becoming increasingly reliant on each other, and this indicates that their role is growing within the cybercrime economy. According to a recent report by CrowdStrike, access broker activity is expected to grow by almost 50% in 2024, as cybercriminals continue to look for ways of infiltrating high-value targets in an increasingly swift and stealthy manner. 

Despite the persistence of ransomware, it is important to remember that individual ransomware groups emerge and dissipate regularly. Several groups, such as Black Basta, appear to have declined over the years or are on the verge of obsolescence, whereas others, such as LockBit, seem to be facing disruptions because of law enforcement interventions. As it seems with LockBit, these groups collapse in the face of internal conflicts, often caused by financial disagreements. Alphv, also known as BlackCat, is one example that exemplifies an exit scam that was carried out 12 months ago. 

According to reports, Alphv kept the entire $22 million ransom paid by UnitedHealth Group to resolve the Change Healthcare breach, instead of sharing it with the affiliate that perpetrated the attack. It is important to note that while some groups have disbanded, the ransomware landscape still remains a highly dynamic place, with new actors constantly emerging on the scene. The so-called "new" groups are usually nothing more than rebranded entities that already have a place in the cybercrime ecosystem. 

These so-called "new" groups include individuals already well versed in the criminality ecosystem. Affiliates - threats actors who collaborate with multiple ransomware operations - are responsible for a significant portion of these attacks, regardless of who they use as their operating name. In 2024, 48 new ransomware groups were discovered, according to cybersecurity firm BlackFog. RunSomeWares claims to have identified four victims on their data leak site which has been compiled by Linkc, while only one victim has been identified by RunSomeWares, according to threat intelligence firm Cyble. However, the long term viability of these emerging groups is uncertain. 

As indicated by the sophistication of the attacks of Anubis, a Russian-speaking ransomware group that became active by December 2024, its tactics were likely developed by former ransomware affiliates. Anubis maintained a visible presence, according to threat intelligence firm Kela, on cybercrime forums such as RAMP and XSS, thereby enhancing its connections within the black market for cybercrime. The group offers a range of illicit services to its customers. There are two main models of ransomware-as-a-service (RaaS) that the organization uses, in which affiliates receive 80% of any ransom payments that are collected from victims that are infected by the group. 

The ransomware of Anubis is capable of attacking Windows, Linux, network-attached storage (NAS), and ESXi environments, as well. Furthermore, the group maintains a Tor-based blog that leaks data, but so far, it has only listed a few victims that have been affected. It advertises two distinctive services in addition to conventional ransomware. The first is a model called data-ransom-as-a-service (DraaS), in which participants receive 60% of all the revenue extorted from victims by using stolen data. 

To qualify, the stolen data must not have been published, must have been obtained within the last six months, and should be considered valuable enough to be published. In its second offering, Anubis claims that publicizing the data breach and notifying local data privacy regulators will increase pressure on victims. The offering targets initial access brokers (IABs) who facilitate cyber intrusions by selling access credentials to compromised networks. Under Anubis' model, it will award half of the ransom obtained from victims who provide their access credentials to the IAB, which will be used to secure a ransom. 

It is important to note, however, that there are some eligibility requirements for this program. The victim must reside in the United States, Canada, Europe, or Australia, and not have been targeted by another ransomware group in the past 12 months. The victim must also not be a government or educational employee. It is, however, still very possible to target the healthcare industry. 

A long history of ransomware groups collaborating with initial access brokers has shown that these brokers often pay a premium for exclusive access to compromised networks. Their increasing dependence on these brokers indicates that their role within the cybercrime economy is growing. According to a recent report published by CrowdStrike, access broker activity increased by nearly 50% in 2024 compared to the previous year, as cybercriminals continued to search for faster and stealthier methods of infiltrating high-value targets as they continued to grow.
