Ransomware Group intelligence
Cl0p
ActiveTrack Cl0p with 14506 published victims, 3 known leak locations, 7 exploited vulnerabilities, and 31 mapped TTPs in a single intelligence view.
Overview
The ransomware group known as Cl0p is a variant of the previously tracked CryptoMix strain. Early Cl0p activity was linked to financially motivated operations attributed to TA505, including phishing campaigns observed in 2019.
Those campaigns commonly relied on macro-enabled documents that deployed the Get2 loader. Once initial access was established, operators moved into reconnaissance, lateral movement, and data exfiltration before deploying ransomware across the victim environment.
After execution, Cl0p variants have been observed appending extensions such as .clop, .CIIp, .Cllp, and .C_L_O_P. Associated ransom notes have included filenames like ClopReadMe.txt, README_README.txt, Cl0pReadMe.txt, and READ_ME_!!!.TXT.
The operation later shifted from phishing-led delivery to intrusion campaigns centered on exploiting vulnerabilities in internet-facing enterprise software and managed file transfer products.

Typical Attacks (17)
▼How Cl0p typically operates, as attributed by MITRE ATT&CK v19.2. Attributed via Clop.
-
T1059.003 Windows Command Shell Execution
What they do: Clop can use cmd.exe to help execute commands on the system.
What that means: Adversaries may abuse the Windows command shell for execution.
-
T1106 Native API Execution
What they do: Clop has used built-in API functions such as WNetOpenEnumW(), WNetEnumResourceW(), WNetCloseEnum(), GetProcAddress(), and VirtualAlloc().
What that means: Adversaries may interact with the native OS application programming interface (API) to execute behaviors.
-
What they do: Clop can make modifications to Registry keys.
What that means: Adversaries may interact with the Windows Registry as part of a variety of other techniques to aid in defense evasion, persistence, and execution.
-
T1027.002 Software Packing Stealth
What they do: Clop has been packed to help avoid detection.
What that means: Adversaries may perform software packing or virtual machine software protection to conceal their code.
-
T1140 Deobfuscate/Decode Files or Information Stealth
What they do: Clop has used a simple XOR operation to decrypt strings.
What that means: Adversaries may use Obfuscated Files or Information to hide artifacts of an intrusion from analysis.
-
T1218.007 Msiexec Stealth
What they do: Clop can use msiexec.exe to disable security tools on the system.
What that means: Adversaries may abuse msiexec.exe to proxy execution of malicious payloads.
-
What they do: Clop has used the sleep command to avoid sandbox detection.
What that means: Adversaries may employ various time-based methods to detect virtualization and analysis environments, particularly those that attempt to manipulate time mechanisms to simulate longer elapses of time.
-
T1553.002 Code Signing Defense Impairment
What they do: Clop can use code signing to evade detection.
What that means: Adversaries may create, acquire, or steal code signing materials to sign their malware or tools.
-
T1685 Disable or Modify Tools Defense Impairment
What they do: Clop can uninstall or disable security products.
What that means: Adversaries may disable, degrade, or tamper with security tools or applications (e.g., endpoint detection and response (EDR) tools, intrusion detection systems (IDS), antivirus, logging agents, sensors, etc.) to impair or reduce visibility of defensive capabilities.
-
T1057 Process Discovery Discovery
What they do: Clop can enumerate all processes on the victim's machine.
What that means: Adversaries may attempt to get information about running processes on a system.
-
T1083 File and Directory Discovery Discovery
What they do: Clop has searched folders and subfolders for files to encrypt.
What that means: Adversaries may enumerate files and directories or may search in specific locations of a host or network share for certain information within a file system.
-
T1135 Network Share Discovery Discovery
What they do: Clop can enumerate network shares.
What that means: Adversaries may look for folders and drives shared on remote systems as a means of identifying sources of information to gather as a precursor for Collection and to identify potential systems of interest for Lateral Movement.
-
T1518.001 Security Software Discovery Discovery
What they do: Clop can search for processes with antivirus and antimalware product names.
What that means: Adversaries may attempt to get a listing of security software, configurations, defensive tools, and sensors that are installed on a system or in a cloud environment.
-
T1614.001 System Language Discovery Discovery
What they do: Clop has checked the keyboard language using the GetKeyboardLayout() function to avoid installation on Russian-language or other Commonwealth of Independent States-language machines; it will also check the GetTextCharset function.
What that means: Adversaries may attempt to gather information about the system language of a victim in order to infer the geographical location of that host.
-
T1486 Data Encrypted for Impact Impact
What they do: Clop can encrypt files using AES, RSA, and RC4 and will add the ".clop" extension to encrypted files.
What that means: Adversaries may encrypt data on target systems or on large numbers of systems in a network to interrupt availability to system and network resources.
-
T1489 Service Stop Impact
What they do: Clop can kill several processes and services related to backups and security solutions.
What that means: Adversaries may stop or disable services on a system to render those services unavailable to legitimate users.
-
T1490 Inhibit System Recovery Impact
What they do: Clop can delete the shadow volumes with vssadmin Delete Shadows /all /quiet and can use bcdedit to disable recovery options.
What that means: Adversaries may delete or remove built-in data and turn off services designed to aid in the recovery of a corrupted system to prevent recovery.

Your network has been penetrated. All files on each host in the network have been encrypted with a strong algorithm. Backups were either encrypted or deleted or backup disks were formatted. Shadow copies also removed, so F8 or any other methods may damage encrypted data but not recover. We exclusively have decryption software for your situation No decryption software is available in the public. DO NOT RESET OR SHUTDOWN – files may be damaged. DO NOT RENAME OR MOVE the encrypted and readme files. DO NOT DELETE readme files. This may lead to the impossibility of recovery of the certain files. Photorec, RannohDecryptor etc. repair tools are useless and can destroy your files irreversibly. If you want to restore your files write to emails (contacts are at the bottom of the sheet) and attach 2-3 encrypted files (Less than 5 Mb each, non-archived and your files should not contain valuable information (Databases, backups, large excel sheets, etc.)). You will receive decrypted samples and our conditions how to get the decoder. Attention!!! Your warranty - decrypted samples. Do not rename encrypted files. Do not try to decrypt your data using third party software. We don`t need your files and your information. But after 2 weeks all your files and keys will be deleted automatically. Contact emails: [email protected] or [email protected] The final price depends on how fast you write to us. Clop
