Direwolf ransomware group
Direwolf is one of the extortion operations we watch continuously. This page covers what is known about the group and the current state of its leak site, which we last saw change 16h ago.
Who they are
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.
Current status
Direwolf's leak site is answering our checks. That does not mean the group is actively posting — plenty of sites stay up for months with nothing new on them — but the infrastructure is live.
The last change we recorded on it was 16h ago (4 Sep 2026 20:30 UTC).
Which organisations this group has named, and when, is part of the SINON platform rather than this page. Create an account to search it, or to be told automatically if a name you care about turns up.
Sectors targeted
This group does not state an industry on its site, so we have nothing reliable to report. Most crews are opportunistic rather than sector-specific in any case — they hit what they can reach.
Watching for your name
If Direwolf posts your company, a supplier or a subsidiary, you want to hear it from us rather than from a journalist. SINON checks these sites continuously and alerts on the names you give it.
