id: feed_sslbl
name: SSL Blacklist Feed
version: 1.0.0
description: "abuse.ch SSL Blacklist (SSLBL) feed connector — pull the botnet C2 blocklists: malicious SSL certificate SHA1 fingerprints, or the associated C2 IP:port list. Emits normalized IOCs (hash or IP + type) for import into the Threat Indicator Manager. Free abuse.ch feed (Auth-Key supported); stdlib-only, no extra Python dependencies."
changelog: "1.0.0 — Initial release: fetch the SSLBL C2 IP list or SSL certificate fingerprint blacklist."
category: feed
# SSLBL is an abuse.ch feed. An Auth-Key (free) is sent as the Auth-Key header
# when provided.
