Ailock ransomware group
Ailock 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 17h ago.
Who they are
AiLock is a Ransomware-as-a-Service (RaaS) group first identified in March 2025. It employs a double-extortion approach—encrypting files and threatening to report breaches to regulators or share stolen data with competitors if the ransom isn’t paid. Victims have just 72 hours to respond and up to five days to pay; failure to pay results in data leaks and destruction of recovery tools. The ransomware appends the extension .AiLock to encrypted files, changes file icons to a green padlock with the “AiLock” name, and replaces the desktop wallpaper with a distinctive robot-skull logo. It employs a hybrid encryption scheme, combining ChaCha20 for file encryption with NTRUEncrypt for securing metadata, and uses a multi-threaded design (path-traversal and encryption threads with IOCP) for efficiency. While active campaigns and leak sites are confirmed, specific sectors, regions, and intrusion methods remain undisclosed in public sources.
Current status
Ailock'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 17h ago (4 Sep 2026 19:31 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 Ailock 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.
