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.

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

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).

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 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.
