GoldenEyeDog
GoldenEyeDog, also referred to as APT-Q-27, is described in the provided content as a Chinese e-crime group. Security researchers linked GoldenEyeDog to the Zhong Stealer campaign, but the content explicitly states that attribution of GoldenEyeDog to the DigiCert breach itself remained unconfirmed. In the reported activity, stolen EV code-signing certificates were used to digitally sign Zhong Stealer payloads. The Zhong Stealer campaign is described as involving credential and cryptocurrency theft and behaving like a remote access trojan. Reported tradecraft associated in the content with the Zhong Stealer activity includes phishing and social-engineering lures using fake screenshots, first-stage decoy payloads, retrieval of additional malware from cloud services such as AWS, and use of digitally signed binaries to evade endpoint detection. Known alias in the content: APT-Q-27.
