Chinese state-sponsored threat actors, specifically a group known as Silver Dragon, have been conducting espionage operations across Southeast Asia and Europe since at least mid-2024. They have targeted government entities in countries such as Russia, Poland, Hungary, Italy, Japan, Myanmar, and Malaysia. Silver Dragon is believed to be affiliated with APT41 and primarily uses phishing emails to initiate attacks, often containing weaponized documents or links. They employ a custom backdoor called GearDoor, which utilizes Google Drive for command-and-control operations, allowing them to exfiltrate stolen intelligence. The group also hijacks legitimate Windows services to load malicious code and uses tools like SSHcmd and Cobalt Strike for post-exploitation activities. Their tactics involve blending malicious activities with normal system operations, making detection difficult and increasing their dwell time within targeted networks.
