Blast radius

Approximate count of dependent hostnames if AS13237 disappeared from the routing table.

Blast radius: Computing — check back later. The precompute pipeline refreshes this panel within a few days.

MOAS / hijack watch

Prefixes routed by AS13237 that another Autonomous System also announces. A non-empty list is one of the strongest BGP-hijack signals available without active probes.

No active MOAS conflicts. Every prefix announced by AS13237 is unique to AS13237 in the current routing snapshot.

Threat posture

Pivot deeper into the graph from AS13237.

Cypher and MCP

Reproduce the headline metric directly against graph.whisper.security:

MATCH (a:ASN {name: "AS13237"})-[:HAS_NAME]->(n:ASN_NAME)
OPTIONAL MATCH (a)-[:HAS_COUNTRY]->(c:COUNTRY)
RETURN a.name AS asn, n.name AS operator, c.name AS country

Or query Whisper from your own LLM workflow via the Whisper MCP server.
