The Qualys Threat Research Team continues to inform enterprise cybersecurity teams of emerging threats that could impact their business. These threat intelligence reports summarize individual threat exploits and provide practical recommendations for protecting against them.
In this free research report, we analyze Quasar RAT which has been widely leveraged by multiple threat actor groups targeting both government and private organizations in Southeast Asia and other geographies.
Quasar RAT (aka: CinaRAT, Yggdrasil) is an open-source remote access trojan (RAT) that has been widely adopted by bad actors due to its powerful techniques. Quasar RAT has been behind multiple attack campaigns by advanced persistent threat (APT) groups and most recently, a Chinese threat group APT10 was observed using it for targeted attacks.
The intelligence in this report can be used by SOC analysts, threat hunting teams, cyberthreat intelligence analysts, and digital forensics teams.
This complementary paper examines the evolution of the Quasar RAT payload, unpacks its configuration, details a technical analysis of the malware payload, and finally presents possible detection parameters using Qualys Multi-Vector EDR.
