Hackers Are Hiding Espionage Infrastructure Inside Ordinary-Looking Casino Websites

Infoblox links China-aligned APT PeckBirdy C2 infrastructure hidden in casino and adult websites targeting Asian government, finance, IT, and education sectors.

Infoblox researchers report that China-aligned APT groups have used casino and adult websites as cover for PeckBirdy, a JavaScript command-and-control framework active since 2023. The sites embed C2 servers, register service workers for persistence, and serve fake browser-update prompts delivering backdoors capable of running commands, stealing credentials, and providing remote access. Targeted sectors across Asia include education, IT, banking, financial services, and government. Just over 3% of Infoblox enterprise customers resolved at least one PeckBirdy C2 domain, with detection coverage on VirusTotal ranging from 13 detections to none.

China-Aligned Hackers Hide PeckBirdy Malware C2 Inside Casino and Adult Websites

Infoblox found China-aligned actors hiding PeckBirdy malware C2 inside fake Chinese-language casino and adult websites, evading security scans via service workers and WebSockets.

Infoblox reported that China-aligned actors behind the PeckBirdy JScript C2 framework conceal command-and-control inside low-quality Chinese-language casino and adult websites, extending Trend Micro's earlier findings that tied the framework to backdoors including MKDOOR and HOLODONUT. One decoy, vip311[.]cc, embedded JavaScript linked to cache-mcp[.]com and registered a service worker connecting to mcp-source[.]online over WebSocket; at publication mcp-source[.]online had zero VirusTotal detections, showing how the layered design evades conventional scanning. The campaign has been active since at least 2023, and just over 3% of Infoblox enterprise customers resolved at least one PeckBirdy C2 domain, with education, IT, banking and government among observed sectors.
