Who they are

CryptNet is a newer Ransomware-as-a-Service (RaaS) operation first identified in April 2023. It follows a double-extortion model, performing data exfiltration before encrypting files. Written in .NET and obfuscated with .NET Reactor, CryptNet utilizes AES-256 (CBC) and RSA-2048 encryption. Its codebase shares strong similarities with Chaos and Yashma ransomware families.

Descriptions are compiled from public reporting and vendor research. They describe how a group has historically operated and can lag its current behaviour; the status and timings above are our own.

Current status

Cryptnet'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 3y ago (17 Oct 2023 20:08 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

Industries this group has been observed going after, most common first.

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 Cryptnet 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.
