Detection packs
Rules for the 5 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
BianLian is a Go-based backdoor named for the extortion group that deploys it. The group moved from encrypting victims to pure data-theft extortion in 2023; its implants beacon to operator-run servers, which are what this corpus lists.
