Dataf Locker ransomware group
Dataf Locker 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 2y ago.
Who they are
DataF Locker is a ransomware variant first observed in 2024, closely tied to the Babuk ransomware lineage. It operates under a double-extortion model, encrypting files by appending the .dataf extension and threatening to leak exfiltrated data if the ransom isn't paid. Victims receive a ransom note named How To Restore Your Files.txt, with satisfaction of specified recovery procedures. Observations suggest use of typical intrusion vectors such as phishing, exploit tools, or leaked credential abuse, although detailed delivery methods and leak infrastructure remain under-documented in high-tier intelligence reports.
Current status
Dataf Locker'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 2y ago (9 Dec 2024 20:36 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 Dataf Locker 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.
