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.
• Direwolf — Dire Wolf is a sophisticated human-operated ransomware group first documented in May 2025, written in Golang using Curve25519/ChaCha20 encryption, targeting manufacturing and technology sectors across 13+ countries with ransoms up to $500,000, operated by a tight core team rather than a broad affiliate program.
• 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.
