Most Active Groups
Group Intelligence
- 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.
- Krybit — Krybit is an emerging RaaS group that launched in late March 2026, offering affiliates an 80/20 revenue split with support for Windows, Linux, ESXi, and NAS device encryption, and became notable for a public feud with rival group 0APT in which each breached and leaked the other's operator data.
- 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.
- Stormous — Stormous is an Arabic-speaking, pro-Russian ransomware and hacktivist group active since at least 2022, known for politically motivated attacks across 15+ countries, collaborating with GhostSec on the GhostLocker 2.0 RaaS platform and inheriting GhostSec's RaaS operations in mid-2024.
