A1project ransomware group
A1project 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.
Who they are
The locker is written in C/C++/ASM.
It supports all systems starting from Windows 2003, has a separate binary for ESXi, and uses a unified encrypted file format across all systems.
WINDOWS:
- Two encryption modes: patch-based and file header.
- Extensive configuration settings: from ignoring specific paths/extensions to terminating services/processes, unlocking occupied files, working with network shares, and more.
- Arguments available for shutting down Hyper-V virtual machines, deleting backups, network scanning with logged-in user tokens.
- Each build includes an obfuscated PowerShell script.
- Execution is password-protected.
- The locker itself is shellcode for x86/x64; if you have custom execution methods, we can provide the shellcode.
ESXI:
- Encrypts files in patches, with configurable path exclusions.
The default configuration is pre-set to avoid disrupting Windows/ESXi/Linux systems.

Current status
A1project'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.
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 A1project 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.
