Most Active Groups
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.
- Safepay — SafePay emerged in September 2024 as a rapidly growing ransomware operation that explicitly disavows the RaaS model and manages all operations internally, claiming over 300 victims worldwide by mid-2025 with a high-profile early attack against UK telematics firm Microlise stealing 1.2 TB of data.
