Crypto24 ransomware group
Crypto24 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
aka Public Data Storage
Crypto24 emerged in early 2025 as a fast-growing double-extortion ransomware-as-a-service (RaaS) group. It targets organizations across industries such as financial services, healthcare, logistics, and technology, with notable victims in Malaysia, Colombia, Egypt, and India. The group executes rapid infiltration—often leveraging stolen credentials—encrypts files (appending the .crypto24 extension), and exfiltrates significant volumes of data (e.g., 2 TB from Vietnam’s CMC Group). Affiliate-oriented operations are indicated by their presence on RAMP forums, suggesting professional recruitment and offering free decryption for small file samples to entice victims.
Current status
Crypto24'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 Crypto24 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.
