Blackhunt ransomware group
Blackhunt 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 1y ago.
Who they are
Black Hunt ransomware has been active since at least mid-2021 and operates under a double-extortion model, encrypting victim files and threatening public release of stolen data via a Tor-based leak site. It primarily targets organizations rather than individuals, with confirmed attacks in sectors including manufacturing, retail, technology, and local government. Encrypted files are appended with the .BlackHunt extension, and ransom notes (Restore_Data.txt) direct victims to Tor portals for negotiation. The ransomware is capable of terminating processes, deleting shadow copies, and disabling recovery functions to maximize impact. Initial access methods include exploitation of vulnerable RDP services and the use of compromised credentials from initial access brokers. While its activity level is smaller compared to major RaaS families, its leak site has featured victims from multiple countries, suggesting an international reach.
Current status
Blackhunt's leak site is not answering. Sites go dark for infrastructure trouble, a deliberate quiet period, or a takedown, and a good number return weeks later under the same name, so the entry stays on the list either way.
The last change we recorded on it was 1y ago (9 Jul 2025 17:07 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 Blackhunt 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.
