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.
- Shinyhunters — ShinyHunters is a financially motivated data-theft and extortion group active since 2020, responsible for high-profile breaches including Ticketmaster (via Snowflake) and PowerSchool; by 2025 they launched a RaaS offering called "shinysp1d3r," and in August 2025 French authorities arrested four members.
- Dragonforce — DragonForce is a major ransomware-as-a-service operation first observed in August 2023 that launched a formal affiliate program offering 80% revenue share, then rebranded as a "ransomware cartel" in 2025, gaining notoriety for high-profile attacks on UK retailers Marks & Spencer, Co-op, and Harrods.
- Threeam — A new Ransomware family identified by the name '3AM' or 'ThreeAM' in September 2023. The ransomware operation was observed by the Symantec team, in which a ransomware affiliate attempted to deploy another ransomware, LockBit, on the target network and then switched to 3AM when LockBit was reportedly blocked.<BR>

> The ransomware operation, according to the publication on its Tor-based website, has been operating since mid-August 2023, according to the publication from its first victim.<BR>Source: https://github.com/crocodyli/ThreatActors-TTPs
