Unveiling ErrTraffic: inside a growing ClickFix malware distribution framework
Sekoia TDR published a comprehensive analysis of ErrTraffic, a JavaScript-based ClickFix malware distribution framework operating as a Malware-as-a-Service (MaaS) on Exploit.IN since December 2025. The framework uses EtherHiding (blockchain-based Dead Drop Resolver) to conceal C2 infrastructure, integrates a Traffic Distribution System (TDS), and has evolved through multiple versions with pricing ranging from $300–$4,500/month. The report documents two distinct operational clusters ("Analytics" and "Beer"), identifies 11 alleged affiliates, and provides forensic analysis of WordPress compromise chains involving credential stuffing, harvested credentials, and persistent PHP backdoors.
