Temper Panda is a cyber-espionage group, assessed with high confidence to operate out of China, that has been active since at least 2007. The group's primary motivation is the theft of valuable data, often aligning with the strategic interests of the Chinese government. Temper Panda is distinguished by its persistent and stealthy operational model, utilizing custom malware and highly targeted campaigns to exfiltrate sensitive information. This group operates under several aliases, including Admin@338, TEMP.Admin, Bronze Vapor, G0018, and MAGNESIUM, and is sometimes associated with APT3.
