CISA Releases Guide to Combat Bulletproof Hosting Abuse
🔒 CISA, working with U.S. and international partners, published Bulletproof Defense: Mitigating Risks from Bulletproof Hosting Providers to provide ISPs and network defenders with practical guidance to identify, disrupt, and mitigate abuse of bulletproof hosting. Bulletproof hosting enables obfuscation, command-and-control, malware delivery, phishing, and hosting of illicit content that supports ransomware, extortion, and DoS campaigns. The guide recommends traffic analysis, curated high-confidence malicious resource lists with automated reviews, customer notifications and filters, and standards for ISP accountability to reduce BPH effectiveness and strengthen network resilience.
