APT-Q-27, also known as GoldenEyeDog, GoldEye Dog, and Dragon Breath, is a Chinese-nexus threat group active since at least 2022 that targets gambling businesses and cryptocurrency-related organizations, including Web3 customer support teams. Jinzhigou was merged into this actor's tracking after matching decryption code was identified in its tooling and an APT-Q-27 Telegram watering-hole operation. APT-Q-27's operations have used watering holes, trojanized software, and customer-support social engineering to deliver Windows backdoors. A state sponsorship relationship has not been established. The group's malware employs multistage delivery, encrypted payloads, in-memory execution, packing or custom virtualization, and extensive anti-debugging and anti-sandbox checks. Its tooling includes remote-command execution, keylogging, and clipboard manipulation. Digitally signed malicious files and legitimate signed applications help conceal execution, while DLL sideloading loads malicious components. Persistence mechanisms include Windows services and registry startup entries; some implants also modify User Account Control settings. Delivery and configuration retrieval can abuse cloud storage and public content-hosting services, with encrypted controller lists or remotely retrieved configuration supporting infrastructure rotation.
