New Attack Lets Hackers Collect and Spoof Browser's Digital Fingerprints

25 October 2021 at 13:19
A "potentially devastating and hard-to-detect threat" could be abused by attackers to collect users' browser fingerprinting information with the goal of spoofing the victims without their knowledge, thus effectively compromising their privacy. Academics from Texas A&M University dubbed the attack system "Gummy Browsers," likening it to a nearly 20-year-old "Gummy Fingers" technique that can

Hardware-grade enterprise authentication without hardware: new SIM security solution for IAM

25 October 2021 at 13:04
The average cost of a data breach, according to the latest research by IBM, now stands at USD 4.24 million, the highest reported. The leading cause? Compromised credentials, often caused by human error. Although these findings continue to show an upward trend in the wrong direction, the challenge itself is not new. What is new is the unprecedented and accelerated complexity of securing the

Russia-linked Nobelium APT targets orgs in the global IT supply chain

25 October 2021 at 11:41

Russia-linked Nobelium APT group has breached at least 14 managed service providers (MSPs) and cloud service providers since May 2021.

The SolarWinds security breach was not isolated, Russia-linked Nobelium APT group has targeted140 managed service providers (MSPs) and cloud service providers and successfully breached 14 of them since May 2021.

The NOBELIUM APT (APT29, Cozy Bear, and The Dukes) is the threat actor that conducted supply chain attack against SolarWinds, which involved multiple families of implants, including the SUNBURST backdoorTEARDROP malwareGoldMax malwareSibot, and GoldFinder backdoors.

NOBELIUM focuses on government organizations, non-government organizations (NGOs), think tanks, military, IT service providers, health technology and research, and telecommunications providers.

The recent large scale campaign uncovered by Microsoft aimed at the service providers was uncovered by Microsoft researchers, in order to avoid detection, threat actors repetitively changed tactics and used a broad range of hacking tools and malware.

“This time, it is attacking a different part of the supply chain: resellers and other technology service providers that customize, deploy and manage cloud services and other technologies on behalf of their customers. We believe Nobelium ultimately hopes to piggyback on any direct access that resellers may have to their customers’ IT systems and more easily impersonate an organization’s trusted technology partner to gain access to their downstream customers.” states Microsoft.

Microsoft is sharing information about the latest activity observed from the threat actor NOBELIUM, which has been attempting to replicate the approach it has used in past attacks by targeting organizations integral to the global IT supply chain: https://t.co/3vJA92CnrB

— Microsoft Security Intelligence (@MsftSecIntel) October 25, 2021

Attackers did not leverage exploits for vulnerabilities in the target organizations, but rather they used well-known techniques, like password spray and spear-phishing.

The campaign confirms that Russia-linked threat actors are trying to gain long-term, systematic access to multiple points in the technology supply chain to carry out cyberespionage activities. 

Microsoft researchers spotted the campaign in its early stages, between July 1 and October 19 the IT giant informed 609 customers that they had been attacked 22,868 times by Nobelium. The number of attacks is very high, by comparison, prior to July 1, 2021, the company had notified customers about attacks from all nation-state actors 20,500 times over the past three years.

The company is still investigating these attacks, anyway the company believes that there was a very low rate of success between July and October.

Microsoft also released technical guidance that can allow organizations to protect themselves against hacking attempts that are part of the latest Nobelium’s campaign.

Microsoft Warns of Continued Supply-Chain Attacks by the Nobelium Hacker Group

25 October 2021 at 10:07
Nobelium, the threat actor behind the SolarWinds compromise in December 2020, has been behind an ongoing wave of attacks that compromised 14 downstream customers of multiple cloud service providers (CSP), managed service providers (MSP), and other IT services organizations, illustrating the adversary's continuing interest in targeting the supply chain via the "compromise-one-to-compromise-many"

NYT Journalist’s iPhone infected twice with NSO Group’sPegasus spyware

25 October 2021 at 09:49

Threat actors infected the iPhone of New York Times journalist Ben Hubbard with NSO Group’s Pegasus spyware between June 2018 to June 2021.

The iPhone of New York Times journalist Ben Hubbard was repeatedly infected with NSO Group’s Pegasus spyware. The device was compromised two times, in July 2020 and June 2021.

The attacks were documented by the Citizen Lab research team from the University of Toronto, the infections took place while the journalist was wording on a book about Saudi Crown Prince Mohammed bin Salman.

“Notably, these infections occurred after Hubbard complained to NSO Group that he was targeted by the Saudi-linked KINGDOM Pegasus operator in June 2018.” reported Citizen Lab. “While we attribute the 2020 and 2021 infections to NSO Group’s Pegasus spyware with high confidence, we are not conclusively attributing this activity to a specific NSO Group customer at this time. However, we believe that the operator responsible for the 2021 hack is also responsible for the hacking of a Saudi activist in 2021.”

Researchers also discovered some forensic artifacts on Hubbard’s iPhone related to the Pegasus spyware as early as April 2018, but it is not clear if they were associated with a genuine infection attempt or some test conducted by the attackers.

The Hubbard’s iPhone was hacked on July 12, 2020 and June 13, 2021, the attackers used the KISMET and FORCEDENTRY zero-click exploits respectively.

The discovery of the attack was possible after another investigation in which the researchers recovered the FORCEDENTRY exploit from a backup of a Saudi activist’s iPhone.

The iMessage account [EMAIL ADDRESS 1] used to deliver to the Saudi activist’s phone the FORCEDENTRY exploit through 31 iMessage attachments was also used to communicate with Hubbard’s phone on June 13, 2021 at 15:45:20 GMT. The researchers noticed that about five minutes before a file was dropped in or deleted from the Library/Caches folder, and at least 41 iMessage attachments were deleted.

“The deleted items all had timestamps greater than June 9, 2021 11:56:46 GMT and less than June 16, 2021 8:46:17 GMT. Based on this pattern of facts, we conclude with high confidence that Hubbard’s iPhone was hacked with NSO Group’s Pegasus spyware on June 13, 2021 15:45:20 GMT.” reads the analysis of the experts.

Experts also reported that Hubbard’s phone logs show the presence of Pegasus infection (aka HIPPOCRENE FACTOR) that took place on July 12, 2020. The initial compromise was introduced onto Hubbard’s phone sometime after January 29, 2020 and before December 14, 2020.

Citizen Lab experts found that Ben Hubbard’s DataUsage.sqlite file showed that process name bh was active on July 13, 2020 16:46:01. This process is associated with Pegasus spyware infections, in this case, attackers likely used the KISMET zero-click iMessage exploit.

“Hubbard was repeatedly subjected to targeted hacking with NSO Group’s Pegasus spyware. The hacking took place after the very public reporting in 2020 by Hubbard and the Citizen Lab that he had been a target. The case starkly illustrates the dissonance between NSO Group’s stated concerns for human rights and oversight, and the reality: it appears that no effective steps were taken by the company to prevent the repeated targeting of a prominent American journalist’s phone.” concludes the report.

The research institute did not attribute the infections to a specific threat actor, NSO Group denied any involvement in the attacks. The New York Times reported a statement from NSO that claims that the journalist “was not a target of Pegasus by any of NSO’s customers.”

NYT Journalist Repeatedly Hacked with Pegasus after Reporting on Saudi Arabia

25 October 2021 at 06:55
The iPhone of New York Times journalist Ben Hubbard was repeatedly hacked with NSO Group's Pegasus spyware tool over a three-year period stretching between June 2018 to June 2021, resulting in infections twice in July 2020 and June 2021. The University of Toronto's Citizen Lab, which publicized the findings on Sunday, said the "targeting took place while he was reporting on Saudi Arabia, and

Emsisoft created a free decryptor for past victims of the BlackMatter ransomware

25 October 2021 at 05:49

Experts from cybersecurity firm Emsisoft announced the availability of a free decryptor for past victims of the BlackMatter ransomware.

Cybersecurity firm Emsisoft has released a free decryption tool for past victims of the BlackMatter ransomware. The researchers found a vulnerability in the encryption process implemented in the BlackMatter ransomware that allowed them to recover encrypted files for free. Emsisoft didn’t reveal the existence of the flaw before to avoid the ransomware group patching the code of their malware.

The decrypter only allows decrypting files encrypted with BlackMatter versions used gang between mid-July and late-September 2021, the most recent version of the ransomware addressed the issue.

Earlier this year, Emsisoft researchers discovered a critical flaw in the BlackMatter ransomware that allowed them to help victims recover their files without paying a ransom, preventing millions of dollars falling into the hands of cybercriminals. The work has been conducted quietly and privately so as not to alert the BlackMatter operators to the flaw. reads the announcement published by Emsisoft.

The company is now urging the victims of the BlackMatter ransomware to contact them to receive support to recover their data without paying the ransom.

PSA: If you or someone you know got hit by BlackMatter in the past couple of months, please reach out. More details can be found here: https://t.co/2AK76UbPFE

— Fabian Wosar (@fwosar) October 24, 2021

The company, with the help of law enforcement agencies, CERTs and private sector partners in multiple countries, is reaching numerous victims to recover their data.

“Beyond BlackMatter, our team has identified vulnerabilities in about a dozen active ransomware families. In these cases, we can recover the vast majority of victims’ encrypted data without a ransom payment. As with BlackMatter, we aren’t making the list of families public until the vulnerability has been found and fixed by their respective operators. This is why we encourage victims to report incidents to law enforcement, as they may be able to direct them to us or other companies that can help.” concludes Emsisoft.

The BlackMatter group launched its operations at at the end of July, the gang claims to be the successor of Darkside and REvil groups. Like other ransomware operations, BlackMatter also set up its leak site where it publishes data exfiltrated from the victims before encrypting their system.

The launch of the BlackMatter ransomware-as-a-service (RaaS) was first spotted by researchers at Recorded Future who also reported that the gang is setting up a network of affiliates using ads posted on two cybercrime forums, such as Exploit and XSS.

The group is recruiting crooks with access to the networks of large enterprises, which have revenues of $100 million/year or larger, in an attempt to infect them with its ransomware. The group is looking for corporate networks in the US, the UK, Canada, or Australia.

BlackMatter ransomware operators announced that they will not target healthcare organizations, critical infrastructure, organizations in the defense industry, and non-profit companies. In August, the gang has implemented a Linux encryptor to targets VMware ESXi virtual machine platform. 

BlackMatter operators have already hit numerous U.S.-based organizations and have demanded ransom payments ranging from $80,000 to $15,000,000 in Bitcoin and Monero.

Using embedded, previously compromised credentials, BlackMatter leverages the Lightweight Directory Access Protocol (LDAP) and Server Message Block (SMB) protocol to access the Active Directory (AD) to discover all hosts on the network. BlackMatter then remotely encrypts the hosts and shared drives as they are found.

Recently, the Cybersecurity and Infrastructure Security Agency (CISA), the Federal Bureau of Investigation (FBI), and the National Security Agency (NSA) have published an advisory that provides details about the BlackMatter ransomware operations and defense recommendations.

The alert also includes Snort signatures that can be used by network defenders to detect the network activity associated with BlackMatter.

CISA, the FBI, and NSA urge network defenders to apply the following mitigations to reduce the risk of compromise by BlackMatter ransomware:

  • Implement Detection Signatures;
  • Use Strong Passwords;
  • Implement Multi-Factor Authentication;
  • Patch and Update Systems;
  • Limit Access to Resources over the Network;
  • Implement Network Segmentation and Traversal Monitoring;
  • Use Admin Disabling Tools to Support Identity and Privileged Access Management;
  • Implement and Enforce Backup and Restoration Policies and Procedures;

TodayZoo phishing kit borrows the code from other kits

24 October 2021 at 20:48

Microsoft uncovered an extensive series of credential phishing campaigns that employed a custom phishing kit tracked as TodayZoo.

Microsoft researchers uncovered a custom phishing kit, dubbed TodayZoo, that was used in an extensive series of credential phishing campaigns.

A “phishing kit” is a set of software or services aimed at facilitating phishing campaigns, In most cases a phishing kit is an archive file containing images, scripts, and HTML pages that allow threat actors to creat a phishing page that is used to trick recipients into providing their credentials.

TodayZoo borrows large pieces of code from other phishing kits investigated by Microsoft in the past, these portions of code also include the comment markers, dead links, and other holdovers from the previous kits.

The kit was first spotted by the IT giant in December 2020, because of the consistency in the redirection patterns, domains, and other techniques, tactics, and procedures (TTPs) of its related campaigns, experts attributes the kit to a threat actor that is behind an old phishing kit template. Microsoft experts specula the three actor has implemented its own credential harvesting logic.

Since March 2021, Microsoft observed a series of phishing campaigns abusing the AwsApps[.]com domain to send the phishing messages. The email messages impersonated Microsoft and leveraged a zero-point font obfuscation technique to evade detection. 

Attackers used different lures in the message body over the months, including password reset, and fake fax and scanner notifications.

todayzoo phishing kit

The analysis of the kit revealed that a large part of the code borrows from the DanceVida phishing kit.

“Upon further investigation, we identified the dead links and markers as holdovers from many other commoditized kits available for free or purchase. We then compared TodayZoo with other phishing kits we have analyzed previously and found that even these kits also contained references to sites like Dancevida[.]com but would have different code blocks for their obfuscation or credential harvest components.” reads the analysis from Microsoft. ““DanceVida” is more of a code block than a full-fledged phishing kit. As such, kits that use DanceVida are rather diverse in their delivery, lures, and location because they are directly for sale on various forums under kit-naming schemas, as well as under a wider variety of landing page templates, including document download pages. Most of the credentials that the DanceVida-based kits’ harvesting pages gather are exfiltrated to accounts using free email services, such as GMail, Yahoo!, and Yandex.”

The imitation and obfuscation-related components of the TodayZoo phishing kit overlap with the code from at least five other kits such as Botssoft, FLCFood, Office-RD117, WikiRed, and Zenfo.

TodayZoo demonstrates that threat actors could create their own variants of phishing kits from publicly available frameworks to meet their needs.

“Our analysis of TodayZoo, DanceVida, and other phishing kits gives us several insights into the underground economy today. First, this research further proves that most phishing kits observed or available today are based on a smaller cluster of larger kit “families.” While this trend has been observed previously, it continues to be the norm, given how phishing kits we’ve seen share large amounts of code among themselves.” concludes Microsoft.

NATO releases its first strategy for Artificial Intelligence

24 October 2021 at 12:19

This week, NATO Defence Ministers released the first-ever strategy for Artificial Intelligence (AI) that encourages the use of AI in a responsible manner.

Artificial Intelligence (AI) is changing the global defence and security environment, for this reason, NATO Defence Ministers released the first-ever strategy for this technology that promotes its development and use in a responsible manner.

Below are NATO principles of responsible use of Artificial Intelligence in defence:

A. Lawfulness: AI applications will be developed and used in accordance with national and international law, including international humanitarian law and human rights law, as applicable.
B. Responsibility and Accountability: AI applications will be developed and used with appropriate levels of judgment and care; clear human responsibility shall apply in order to ensure accountability.
C. Explainability and Traceability: AI applications will be appropriately understandable and transparent, including through the use of review methodologies, sources, and procedures. This includes verification, assessment and validation mechanisms at either a NATO and/or national level.
D. Reliability: AI applications will have explicit, well-defined use cases. The safety, security, and robustness of such capabilities will be subject to testing and assurance within those use cases across their entire life cycle, including through established NATO and/or national certification procedures.
E. Governability: AI applications will be developed and used according to their intended functions and will allow for: appropriate human-machine interaction; the ability to detect and avoid unintended consequences; and the ability to take steps, such as disengagement or deactivation of systems, when such systems demonstrate unintended behaviour.
F. Bias Mitigation: Proactive steps will be taken to minimise any unintended bias in the development and use of AI applications and in data sets.

The new strategy also aims at accelerating and mainstream AI adoption in capability development and delivery, enhancing interoperability within the Alliance. NATO encourages to protect and monitor AI technologies used by its members.

The Alliance warns of malicious use of AI by threat actors and urges the adoption of measures and technologies to identify and safeguard against these threats.

NATO Allies have recognized seven high-priority technological areas for defence and security, including Artificial Intelligence. These technologies include quantum-enabled technologies, data and computing, autonomy, biotechnology and human enhancements, hypersonic technologies, and space.

NATO stresses the importance of addressing these technologies in an ethical way, all of them are dual-use and very pervasive.

“Some state and non-state actors will likely seek to exploit defects or limitations within our AI technologies. Allies and NATO must strive to protect the use of AI from such interference, manipulation, or sabotage, in line with the Reliability Principle of Responsible Use, also leveraging AI-enabled Cyber Defence applications.” concludes the announcement. “Allies and NATO should develop adequate security certification requirements for AI, such as specific threat analysis frameworks and tailored security audits for purposes of ‘stress-testing’. AI can impact critical infrastructure, capabilities and civil preparedness—including those covered by NATO’s seven resilience Baseline Requirements—creating potential vulnerabilities, such as cyberspace, that could be exploited by certain state and non-state actors.”

Threat actors offer for sale data for 50 millions of Moscow drivers

24 October 2021 at 09:47

Threat actors are offering for sale a database containing 50 million records belonging to Moscow drivers on a hacking forum for $800.

Bad news for Russian drivers, threat actors are selling a database containing 50 million records belonging to Moscow drivers on a hacking forum for only $800. The threat actors claim to have obtained the data from an insider in the local police, they published a sample of database records containing model of the car, its registration and VIN number, date of registration, engine power, name of the owner, date of birth, and phone number. 

Stolen data spans from 2006 and 2019, local media outlets have confirmed their authenticity. Threat actors are also offering a file containing information from 2020 to those that will buy the database.

“The cybercriminals put up for sale for $ 800 a database of 50 million lines with the data of drivers that were registered in Moscow and the Moscow region from 2006 to 2019. As a bonus to the purchase, a file with information from 2020 is offered. The database contains names, dates of birth, phone numbers, VIN-codes and numbers of cars, their brands and models, as well as the year of registration. The seller himself claims that he received information from an insider in the traffic police.” reads the post published by the Kommersant website.

Alexei Parfentiev, head of the analytics department at SerchInform, confirmed this scenario:

“It looks more likely also because the requirements of regulators to such structures as the traffic police, in terms of protection against external attacks, are extremely strict,” he says.

However Kommersant speculates that the data was obtained by hacking into the level of regional information systems.

Andrey Arsentiev, head of analytics and special projects at InfoWatch Group, believes that the the data could have been obtained by external attackers, for example, by exploiting a vulnerability in the system software.

“Judging by the composition of the data, the new database of car owners is not an unloading from the traffic police system, but rather an unloading from the databases of insurers, the founder of the DLBI data leak intelligence and darknet monitoring service Ashot Hovhannisyan believes.” continues the post.

“This data could be stolen both directly from the insurance companies and from their contractors to whom the bases are transferred for “ringing”. says Ashot Hovhannisyan.

The availability of this data in the cybercrime underground poses serious risks to the exposed individuals, attackers can use the information to carry out several malicious activities.

Cisco SD-WAN flaw could lead to arbitrary code execution, patch it now!

23 October 2021 at 20:24

Cisco fixes an OS command-injection flaw, tracked as CVE-2021-1529, in Cisco SD-WAN that could allow privilege escalation and lead to arbitrary code execution.

Cisco addressed a high-severity OS command-injection vulnerability, tracked as CVE-2021-1529, in Cisco SD-WAN that could allow privilege escalation and lead to arbitrary code execution.

Cisco SD-WAN is a cloud-delivered overlay WAN architecture that enables digital and cloud transformation at enterprises, it allows to connect disparate office locations via the cloud.

An authenticated, local attacker can exploit the CVE-2021-1529 vulnerability to execute arbitrary commands with root privileges. The CVE-2021-1529 received a CVSS score of 7.8,

“The vulnerability is due to insufficient input validation by the system CLI. An attacker could exploit this vulnerability by authenticating to an affected device and submitting crafted input to the system CLI. A successful exploit could allow the attacker to execute commands on the underlying operating system with root privileges.” reads the advisory published by the IT giant.

Cisco has released software updates to address this flaw, the company pointed out that there are no workarounds that fix this issue.

The Cisco PSIRT is not aware of attacks in the wild exploiting this vulnerability.

The US Cybersecurity and Infrastructure Security Agency (CISA) also published a security advisory for this flaw that urge organizations to address this vulnerability.

“CISA encourages users and administrators to review Cisco Advisory cisco-sa-sd-wan-rhpbE34A and apply the necessary updates.” states CISA’s advisory.

Supply-chain attack on NPM Package UAParser, which has millions of daily downloads

23 October 2021 at 13:03

The U.S. CISA warned of crypto-mining malware hidden in a popular JavaScript NPM library, named UAParser.js, which has millions of weekly downloads.

The U.S. Cybersecurity and Infrastructure Security Agency published an advisory to warn of the discovery of a crypto-mining malware in the popular NPM Package UAParser.js. The popular library has million of weekly downloads.

“Versions of a popular NPM package named ua-parser-js was found to contain malicious codeua-parser-js is used in apps and websites to discover the type of device or browser a person is using from User-Agent data. A computer or device with the affected software installed or running could allow a remote attacker to obtain sensitive information or take control of the system.” reads the advisory. “CISA urges users and administers using compromised ua-parser-js versions 0.7.29, 0.8.0, and 1.0.0 to update to the respective patched versions: 0.7.30, 0.8.1, 1.0.1.”

The analysis of the experts revealed that at least three tainted versions of the package were uploaded to the repository, versions 0.7.29, 0.8.0, and 1.0.0.

According to the maintainer of the library,Faisal Salman, a threat actor has hijacked his NPM account to publish the infected packages.

“I noticed something unusual when my email was suddenly flooded by spams from hundreds of websites (maybe so I don’t realize something was up, luckily the effect is quite the contrary).” wrote the maintainer of the UAParser.js.

“I believe someone was hijacking my npm account and published some compromised packages (0.7.290.8.01.0.0) which will probably install malware as can be seen from the diff here: https://app.renovatebot.com/package-diff?name=ua-parser-js&from=0.7.28&to=1.0.0. I have sent a message to NPM support since I can’t seem to unpublish the compromised versions (maybe due to npm policy https://docs.npmjs.com/policies/unpublish) so I can only deprecate them with a warning message.”

The tainted versions were replaced with clean versions 0.7.30, 0.8.1, and 1.0.1.

“The npm package ua-parser-js had three versions published with malicious code. Users of affected versions (0.7.29, 0.8.0, 1.0.0) should upgrade as soon as possible and check their systems for suspicious activity. See this issue for details as they unfold.” reads another alert published by GitHub. “Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.”

The CISA’s alert comes a few days after the researchers from the security firm Sonatype have uncovered crypto-mining malware hidden inside three JavaScript libraries uploaded on the official npm package repository. The names of the three npm packages were klowklownokhsa that were installing cryptocurrency miners on both Windows or Linux platforms.

The good news is that the above packages remained on the repository only for a day before they were discovered.

Facebook SSRF Dashboard allows hunting SSRF vulnerabilities

22 October 2021 at 22:05

Facebook developed a new tool that allows security experts to look for Server-Side Request Forgery (SSRF) vulnerabilities in their software.

Facebook announced to have designed a new tool, named SSRF Dashboard, that allows security researchers to search for Server-Side Request Forgery (SSRF) vulnerabilities.

Server-side request forgery is a web security vulnerability that allows an attacker to induce the server-side application to make HTTP requests to an arbitrary domain chosen by the attacker.

“In a typical SSRF attack, the attacker might cause the server to make a connection to internal-only services within the organization’s infrastructure. In other cases, they may be able to force the server to connect to arbitrary external systems, potentially leaking sensitive data such as authorization credentials.”

“This tool is a simple UI where researchers can generate unique internal endpoint URLs for targeting. The UI will then show the number of times these unique URLs have been hit as a result of a SSRF attempt. Researchers can leverage this tool as part of their SSRF proof of concept to reliably determine if they have been successful.” states Facebook.

SSRF Dashboard allows researchers to create unique internal endpoint URLs that could be targeted by SSRF attacks and determine if they have been hit. The tool allows researchers to test their SSRF proof-of-concept (PoC) code.

Pentesters could report any SSRF flat to the company by including the ID of the SSRF attempt url that they used along with their PoC.

Groove ransomware operators call on other ransomware groups to stop competing and join the forces to fight against the US.

The Groove ransomware gang is calling on other ransomware groups to attack US public sector after a an operation of of law enforcement shut down the infrastructure of the REvil gang.

“The ransomware group REvil was itself hacked and forced offline this week by a multi-country operation, according to three private sector cyber experts working with the United States and one former official.” reported the Reuters agency.

The ransomware gang published a message in Russian language on its leak site:

The message also asks other ransomware gangs to avoid targeting Chinese companies, because China could represent a safe place for ransomware gangs in case Russia will stop tolerate ransomware operations.

“In our difficult and troubled time when the US government is trying to fight us, I call on all partner programs to stop competing, unite and start fucking up the US public sector” states the message. “I urge not to attack Chinese companies, because where do we pinch if our homeland suddenly turns away from us, only to our good neighbors – the Chinese!”

After the news of the recent shutdown of REvil’s infrastructure by law enforcement agencies, the gangs behind the Darkside and BlackMatter ransomware operations have moved 107 BTC ($6.8 million).

Omri Segev Moyal, CEO and co-founder of security firm Profero, told TheRecord that the threat actors split the funds into multiple wallets. The gang is likely moving the funds to cache out its profits. Moyal shared his findings with law enforcement.
