| Description | (SecureWorks) HUI Loader is a custom DLL loader whose name is derived from a string in the loader (see Figure 1). The malware is loaded by legitimate programs that are vulnerable to DLL search order hijacking. HUI Loader decrypts and loads a third file containing an encrypted payload that is also deployed to the compromised host. CTU researchers have observed HUI Loader loading RATs such as SodaMaster, PlugX, Cobalt Strike, and QuasarRAT. | |
