Who they are

Apos ransomware surfaced in April 2024 and is best characterized as a data‑broker or leak‑only operation, rather than a traditional file‑encryption ransomware. It has not been observed to conduct encryption, but instead focuses on data exfiltration with threats to leak or sell the stolen information. Targets span sectors such as technology, healthcare, manufacturing, business services, telecommunications, and government—with significant victimology in Brazil, the United States, India, France, Paraguay, and Spain. Reporting suggests its activity tapered off after a few incidents, possibly indicating a one-time campaign or short-lived operation. Though some sources list multiple victims, technical details such as encryption algorithms, ransom notes, or extortion pricing are not publicly documented. Apos is sometimes listed among new or industrial-focused threats observed in Q1 2025, but remains poorly defined in public technical intel.

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

Apos'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 11mo ago (2 Oct 2025 04:16 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 Apos 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.
