Cryakl ransomware group
Cryakl 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
also known as “Fantomas”.
Cryakl first appeared in 2014, spreading primarily across Eastern Europe and Russia via phishing emails with malicious attachments. It uses an asymmetric RSA-based encryption scheme, appending victim-specific IDs and contact emails into filenames and ransom notes. The ransomware operates under a RaaS-like model, distributing builds to affiliates for broader dissemination. In 2018, Belgian law enforcement seized Cryakl’s command-and-control infrastructure and recovered decryption keys, enabling victims to restore files via free tools like Kaspersky’s RakhniDecryptor and the NoMoreRansom project.
Current status
Cryakl'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 Cryakl 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.
