MOAS / hijack watch
Prefixes routed by AS513 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 AS513 is unique to AS513 in the current routing snapshot.

Cypher and MCP
Reproduce the headline metric directly against graph.whisper.security:
MATCH (a:ASN {name: "AS513"})-[:HAS_NAME]->(n:ASN_NAME)
OPTIONAL MATCH (a)-[:HAS_COUNTRY]->(c:COUNTRY)
RETURN a.name AS asn, n.name AS operator, c.name AS countryOr query Whisper from your own LLM workflow via the Whisper MCP server.
