Ransomware group

direwolf

Dire Wolf is a recently emerged double-extortion ransomware group that first appeared around May 2025. It is a crypto-ransomware and data broker targeting industries like manufacturing and technology across multiple countries, including the U.S., Thailand, Taiwan, Singapore, Türkiye, among others. Written in Go and delivered as a UPX-packed binary, it utilizes robust encryption (Curve25519 and ChaCha20) to lock files with a .direwolf extension, while deleting backups, disabling logging, and terminating key services to block recovery. Victims receive highly customized ransom notes containing live-chat credentials and victim-specific portals, indicating a highly professional and targeted approach.
