What is Bulletproof hosting?
Hosting providers that knowingly ignore abuse complaints and takedown requests, giving criminals somewhere to keep servers online.
Bulletproof hosting providers sell servers and network space with a promise to ignore abuse reports and resist takedowns. They often operate from jurisdictions where enforcement is weak, or behind layers of shell companies and resellers.
Phishing sites, C2 servers, malware distribution and spam infrastructure cluster on these networks. Knowing which ASNs and providers behave this way is a useful enrichment signal.
