• 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.
• 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.
• 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.
