Cl0p Ransomware | Breaking Cybersecurity News | The Hacker News

Dozens of organizations may have been impacted following the zero-day exploitation of a security flaw in Oracle's E-Business Suite (EBS) software since August 9, 2025 , Google Threat Intelligence Group (GTIG) and Mandiant said in a new report released Thursday. "We're still assessing the scope of this incident , but we believe it affected dozens of organizations," John Hultquist, chief analyst of GTIG at Google Cloud, said in a statement shared with The Hacker News. "Some historic Cl0p data extortion campaigns have had hundreds of victims. Unfortunately, large-scale zero-day campaigns like this are becoming a regular feature of cybercrime." The activity, which bears some hallmarks associated with the Cl0p ransomware crew, is assessed to have fashioned together multiple distinct vulnerabilities, including a zero-day flaw tracked as CVE-2025-61882 (CVSS score: 9.8), to breach target networks and exfiltrate sensitive data. Google said it found evidence of ...

Threat intelligence firm GreyNoise is warning of a "notable surge" in scanning activity targeting Progress MOVEit Transfer systems starting May 27, 2025—suggesting that attackers may be preparing for another mass exploitation campaign or probing for unpatched systems. MOVEit Transfer is a popular managed file transfer solution used by businesses and government agencies to share sensitive data securely. Because it often handles high-value information, it has become a favorite target for attackers.  "Prior to this date, scanning was minimal — typically fewer than 10 IPs observed per day," the company said . "But on May 27, that number spiked to over 100 unique IPs, followed by 319 IPs on May 28." Since then, daily scanner IP volume has remained intermittently elevated between 200 to 300 IPs per day, GreyNoise added, stating it marks a "significant deviation" from usual behavior. As many as 682 unique IPs have been flagged in connection with th...

2023 CL0P Growth  Emerging in early 2019, CL0P was first introduced as a more advanced version of its predecessor the 'CryptoMix' ransomware, brought about by its owner CL0P ransomware, a cybercrime organisation. Over the years the group remained active with significant campaigns throughout 2020 to 2022. But in 2023 the CL0P ransomware gang took itself to new heights and became one of the most active and successful ransomware organizations in the world.  Capitalizing on countless vulnerabilities and exploits for some of the world's largest organizations. The presumed Russian gang took its name from the Russian word "klop," which translates to "bed bug" and is often written as "CLOP" or "cl0p". Once their victims' files are encrypted, ".clop" extensions are added to their files.  CL0P's Methods & Tactics  The CL0P ransomware gang (closely associated with the TA505. FIN11, and UNC2546 cybercrime groups) was renowned for their extremely destructive and aggressi...

Progress Software on Thursday  disclosed  a third vulnerability impacting its MOVEit Transfer application, as the Cl0p cybercrime gang deployed extortion tactics against affected companies. The  new flaw , which is being tracked as CVE-2023-35708 , also concerns an SQL injection vulnerability that "could lead to escalated privileges and potential unauthorized access to the environment." The company is urging its customers to disable all HTTP and HTTPs traffic to MOVEit Transfer on ports 80 and 443 to safeguard their environments while a fix is being prepared to address the weakness. The cloud managed file transfer solution has been fully patched. The revelation comes a week after Progress  divulged  another set of SQL injection vulnerabilities ( CVE-2023-35036 ) that it said could be weaponized to access the application's database content. The vulnerabilities join  CVE-2023-34362 , which was  exploited  as a zero-day by the Clop ransomware g...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) and Federal Bureau of Investigation (FBI) have published a joint advisory regarding the active exploitation of a  recently disclosed critical flaw  in Progress Software's MOVEit Transfer application to drop ransomware. "The Cl0p Ransomware Gang, also known as TA505, reportedly began exploiting a previously unknown SQL injection vulnerability in Progress Software's managed file transfer (MFT) solution known as MOVEit Transfer," the agencies  said . "Internet-facing MOVEit Transfer web applications were infected with a web shell named LEMURLOOT, which was then used to steal data from underlying MOVEit Transfer databases." The prolific cybercrime gang has since  issued an ultimatum  to several impacted businesses, urging them to get in touch by June 14, 2023, or risk getting all their stolen data published. Microsoft is tracking the activity under the moniker  Lace Tempest  (aka Storm-...

Iranian nation-state groups have now joined financially motivated actors in actively exploiting a critical flaw in PaperCut print management software, Microsoft disclosed over the weekend. The tech giant's threat intelligence team said it observed both Mango Sandstorm (Mercury) and Mint Sandstorm (Phosphorus) weaponizing CVE-2023-27350 in their operations to achieve initial access. "This activity shows Mint Sandstorm's continued ability to  rapidly incorporate [proof-of-concept] exploits  into their operations," Microsoft  said  in a series of tweets. On the other hand, CVE-2023-27350 exploitation activity associated with Mango Sandstorm is said to be on the lower end of the spectrum, with the state-sponsored group "using tools from prior intrusions to connect to their C2 infrastructure." It's worth noting that  Mango Sandstorm  is linked to Iran's Ministry of Intelligence and Security (MOIS) and  Mint Sandstorm  is associated with the Islam...

Microsoft has confirmed that the  active exploitation of PaperCut servers  is linked to attacks that are designed to deliver Cl0p and LockBit ransomware families. The tech giant's threat intelligence team is attributing a subset of the intrusions to a financially motivated actor it tracks under the name  Lace Tempest  (formerly DEV-0950), which overlaps with other hacking groups like FIN11, TA505, and Evil Corp. "In observed attacks, Lace Tempest ran multiple PowerShell commands to deliver a TrueBot DLL, which connected to a C2 server, attempted to steal LSASS credentials, and injected the  TrueBot payload  into the conhost.exe service," Microsoft  said  in a series of tweets. The next phase of the attack entailed the deployment of Cobalt Strike Beacon implant to conduct reconnaissance, move laterally across the network using WMI, and exfiltrate files of interest via the file-sharing service MegaSync. Lace Tempest is a Cl0p ransomware affilia...

The cybercrime ring that was apprehended last week in connection with Clop (aka Cl0p) ransomware attacks against dozens of companies in the last few months helped launder money totaling $500 million for several malicious actors through a plethora of illegal activities. "The group — also known as FANCYCAT — has been running multiple criminal activities: distributing cyber attacks; operating a high-risk exchanger; and laundering money from dark web operations and high-profile cyber attacks such as Cl0p and Petya ransomware," popular cryptocurrency exchange Binance  said  Thursday. On June 16, the Ukraine Cyber Police  nabbed six individuals  in the city of Kyiv, describing the arrests as resulting from an international operation involving law enforcement authorities from Korea, the U.S., and Interpol. While the bust was seen as a major blow to the operations of the Clop gang, the hackers published earlier this week a fresh batch of confidential employee records st...
