Most Active Groups
Group Intelligence
- Lockbit5 — LockBit 5.0 ("ChuongDong") emerged in September 2025 as the group's resurgence following the February 2024 law enforcement takedown, introducing cross-platform payloads targeting Windows, Linux, and VMware ESXi with enhanced evasion capabilities and continuing the RaaS affiliate model of its predecessors.
- 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.
- Aurora — Aurora is a ransomware group associated with a multi-purpose Go-based malware distributed by multiple criminal teams from mid-2022, also sold as an infostealer/botnet under the same name on underground forums.
- Nova — Nova (formerly RALord) is a ransomware-as-a-service (RaaS) group that encrypts victims’files and uses double-extortion tactics to pressure organizations into paying for decryption and data non-disclosure.
