How ScanMalware builds this profile

ScanMalware.com performs public URL scans with a real headless browser, then maps each scanned host to its current ASN ownership and BGP routing context. This profile is built from those scans plus live routing data — the IP prefixes AS1299 announces, the networks that transit it, and the country it operates from — letting you pivot from one suspicious host to the wider network it sits on.
