Threat-intelligence feed
General BlacklistsLast verified Page fetched
FireHOL Level 1 is a general blacklists threat-intelligence feed tracked by WhisperGraph as a FEED_SOURCE node. The Whisper Internet Directory publishes this page so security analysts and LLM agents can link to it as a stable record for FireHOL Level 1.
FireHOL Level 1 is the most conservative tier of the FireHOL IP lists project — a high-confidence deny-list intended for safe deployment as a default-block at perimeter firewalls. It is composed of upstream feeds with extremely low false-positive rates: bogon address ranges, Spamhaus DROP and EDROP, dshield.org's recommended block list, and a small number of similarly stable sources. Level 2 and Level 3 add progressively more aggressive sources at the cost of higher false-positive rates. Level 1 is the most commonly deployed of the three because the false-positive risk is low enough that operators feel comfortable blocking on it without a manual review step.
FEED_SOURCE node confirmed. WhisperGraph carries this feed under the same category (General Blacklists) as the editorial entry above. The graph identifier firehol-level1 matches the live f.id property.
Live indicator listings: not yet available. WhisperGraph's LISTED_INedge is virtual and not enumerable from the feed side — there is no query-tractable way today to fetch the IPs and hostnames listed in this feed without first visiting every candidate indicator. Indicator-anchored queries work in the opposite direction (see the Cypher snippet below) and the directory's individual IP and host pages surface their feed memberships individually. Per-feed enumeration (an indicator count and sample of representative indicators) is on the roadmap.
Look up which threat feeds list a given IP — the indicator-anchored query that powers the threat card:
MATCH (ip:IPV4 {name: $ip})-[:LISTED_IN]->(f:FEED_SOURCE)
WHERE f.name = "FireHOL Level 1"
WITH f
MATCH (f)-[:BELONGS_TO]->(c:CATEGORY)
RETURN f.name AS feed, c.name AS categoryVerify the feed's graph-side identity directly:
MATCH (f:FEED_SOURCE {name: "FireHOL Level 1"})
OPTIONAL MATCH (f)-[:BELONGS_TO]->(c:CATEGORY)
RETURN f.id AS id, f.name AS name, c.name AS categoryOr query Whisper from your own LLM workflow via the Whisper MCP server.
