Most Active Groups

Group Intelligence

• Clop — The ransomware group known as Cl0p is a variant of a previously known strain dubbed CryptoMix. It is worth noting that this variant was delivered as the final payload in a phishing campaign in 2019 and was exclusively financially motivated, with attacks carried out by the threat actors TA505.<br> <br> At that time, malicious actors sent phishing emails that led to a macro-enabled document that would drop a loader called 'Get2.' After gaining an initial foothold in the system or infrastructure, the actors began using reconnaissance, lateral movement, and exfiltration techniques to prepare for the deployment of the ransomware.<br> <br> After the execution of the ransomware, Cl0p appends the extension '.clop' to the end of files, or other types of extensions such as '.CIIp, .Cllp, and .C_L_O_P,' as well as different versions of the ransom note that were also observed after encryption. Depending on the variant, any of the ransom text files were created with names like 'ClopReadMe.txt, README_README.txt, Cl0pReadMe.txt, and READ_ME_!!!.TXT.'<br> <br> The Clop operation has shifted from delivering its final payload via phishing and has begun initiating attacks using vulnerabilities that resulted in the exploitation and infection of victims' infrastructures.<BR>Source: https://github.com/crocodyli/ThreatActors-TTPs
• Qilin — Qilin ransomware was first observed in July of 2022. Qilin Ransomware is written in Golang and supports multiple encryption modes; all of which are controlled by the operator. Qilin actors practice double extortion – demanding payment for a decryptor, as well as for the non-release of stolen data.
• Thegentlemen — The Gentlemen is a RaaS group that emerged in July–August 2025, rapidly claiming over 320 victims across 17+ countries by offering affiliates a 90% revenue share, deploying a Go-based locker against Windows, Linux, NAS, and BSD systems; a compromised C2 server in 2026 revealed more than 1,570 linked victims.
• Orova — First seen 2026-07-07
• Incransom — INC Ransom is a prolific ransomware-as-a-service operation active since July 2023 that systematically targets healthcare, government, education, and manufacturing sectors in North America and Europe, having posted over 200 victims in 2025 alone with no sector off-limits.
