Five Eyes cybersecurity agencies released mitigation guidance for internet service providers and network defenders to reduce abuse of bulletproof hosting providers, which cybercriminals use for phishing, malware delivery, and command-and-control activity. The guidance matters because it gives defenders concrete steps to identify and block malicious infrastructure without blindly disrupting legitimate traffic. It also adds operational pressure on hosting providers that are used to shield ransomware and other criminal operations.
