Detection packs

Rules for the 367 still-listed addresses on this page, regenerated as the archive updates; archived episodes are omitted, and a rule can lag a withdrawal by up to five minutes. Suricata rules are rev:2 — alert tcp on address and port, alert tls where a full certificate fingerprint is published — and carry the archive's own episode ids as sids, so packs load beside each other and beside any per-host file. YARA packs are hash matches only: this site holds no file bytes.

About

Commercial red-team tooling whose cracked builds have been the most common post-exploitation framework in criminal use for a decade. Its team servers are identifiable by certificate, by the JARM and JA4X shapes of that certificate, and — where the profile was left default — by a beacon configuration that names the operator's callback host and a watermark identifying the licence the build came from. Re-labelled by the upstream in place: 1 host earlier labelled Mozi. The archive keeps only the most recent earlier label per episode. Recently first observed in AS153706 on 2026-09-14 (1 host); AS15169 on 2026-09-11 (1 host); AS932 on 2026-09-10 (1 host); AS44620 on 2026-09-10 (1 host); AS201814 on 2026-09-09 (1 host); AS213194 on 2026-09-08 (1 host) — networks this family had not appeared in before, as seen by this archive.
