Most Active Groups

N0N 64 Thegentlemen 42 Qilin 29 Wallstreet 14 Akira 12

Group Intelligence

  • 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.
  • 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.
  • Akira — The Akira ransomware group is said to have emerged in March 2023, and there's much speculation about its ties to the former CONTI ransomware group.<br> <br> It's worth noting that with the end of CONTI's operation, several affiliates migrated to independent campaigns such as Royal, BlackBasta, and others.<br> <br> According to some reports, Akira affiliates also work with other ransomware operations, such as Snatch and BlackByte, as an open directory of tools used by an Akira operator was identified, which also had connections to the Snatch ransomware.<br> <br> The first version of the Akira ransomware was written in C++ and appended files with the '.akira' extension, creating a ransom note named 'akira_readme.txt,' partially based on the Conti V2 source code. However, on June 29, 2023, a decryptor for this version was reportedly released by Avast.<br> <br> Subsequently, a version was released that fixed the decryption flaw on July 2, 2023. Since then, the new version is said to be written in Rust, this time called 'megazord.exe,' and it changes the extension to '.powerranges' for encrypted files.<br> <br> Most of Akira's initial access vectors use brute-force attempts on Cisco VPN devices (which use single-factor authentication only).<br> Additionally, exploitation of CVEs: CVE-2019-6693 and CVE-2022-40684 for initial access has been identified.<BR>Source: https://github.com/crocodyli/ThreatActors-TTPs
