Test Panda is a cyber threat actor identified as an Advanced Persistent Threat (APT) group, first observed in early 2015. The group is assessed with high confidence to be of Chinese origin, consistent with CrowdStrike's 'Panda' naming convention for Chinese state-sponsored groups. Test Panda primarily engages in espionage campaigns, focusing on long-term surveillance and data exfiltration from government and private sectors. They distinguish themselves through their frequent use of zero-day vulnerabilities to infiltrate secure networks and their reliance on stealthy operations and advanced malware variants. While Test Panda is often listed alongside other 'Panda' groups such as Electric Panda and Gibberish Panda, these are generally considered distinct entities rather than direct aliases for Test Panda itself.
