The malware is loaded by legitimate programs that are\r\nvulnerable to DLL search order hijacking. HUI Loader decrypts and loads a third file\r\ncontaining an encrypted payload that is also deployed to the compromised host. CTU\r\nresearchers have observed HUI Loader loading RATs such as SodaMaster, PlugX,\r\nCobalt Strike, and QuasarRAT.\r\nInformation\r\n\u003chttps://www.secureworks.com/research/bronze-starlight-ransomware-operations-use-hui-loader\u003e\r\nMITRE ATT\u0026CK
