CISA Issues Guidance to Combat Bulletproof Hosting Abuse

🔒 CISA, together with US and international partners, has published a joint guide addressing bulletproof hosting (BPH) services that enable ransomware, phishing, malware delivery and other attacks. The guidance explains how BPH providers lease or resell infrastructure to criminals, enabling fast-flux operations, command-and-control activity and data extortion while evading takedowns. It recommends concrete defensive actions — including curating a high confidence list of malicious internet resources, continuous traffic analysis, automated blocklist reviews, network-edge filters, threat intelligence sharing and feedback processes — to help ISPs and network defenders reduce abuse while limiting collateral impact.

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.

Dutch Police Seize 250 Servers Used by Bulletproof Hosting

🛑 Dutch police seized around 250 physical servers and thousands of virtual machines tied to a bulletproof hosting service that allegedly catered exclusively to cybercriminals. Authorities say the infrastructure has been used since 2022 in more than 80 investigations and facilitated ransomware, botnets, phishing, and distribution of child abuse content. Investigators will perform forensic analysis on the seized systems to identify operators and clients. No arrests have been announced; the provider CrazyRDP has reportedly gone offline after the action.

Ukrainian AS FDN3 Linked to Massive Brute-Force Attacks

🔒 Intrinsec reports that Ukraine-based autonomous system FDN3 (AS211736) conducted widespread brute-force and password-spraying campaigns targeting SSL VPN and RDP endpoints between June and July 2025, with activity peaking July 6–8. The firm links FDN3 to two other Ukrainian ASes (AS61432, AS210950) and a Seychelles operator (AS210848) that frequently exchange IPv4 prefixes to evade blocklisting. Intrinsec highlights ties to bulletproof hosting providers and a Russian-associated Alex Host LLC, stressing that offshore peering arrangements complicate attribution and takedown efforts.
