Certificate 266bb301d68f…

3 convicted hosts served this exact certificate — 3 still listed. A shared certificate is the strongest link this corpus draws between two addresses, though it evidences a shared BUILD rather than a shared operator.

self-signed · subject :3232 · valid 2026-07-08 → 2026-08-07 · 2048-bit

A self-signed certificate can claim any subject, so a familiar name here is an impersonation attempt, not a domain any of these hosts owns.

Detection packs

Rules for the 3 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.

Addresses

Ordered by when this archive first recorded them, newest first — a stable ordering, so a page holds the same addresses tomorrow. Archived addresses are included and marked; they are the majority of this corpus over time.
