Trusted DesignDell SecureWorks Counter Threat Unit(TM) (CTU) researchers analyzed multiple versions of a remote access trojan (RAT) named Sakula (also known as Sakurel and VIPER). The RAT, which according to compile timestamps first surfaced in November 2012, has been used in targeted intrusions through 2015. Sakula enables an adversary to run interactive commands as well as to download and execute additional components. Sakula uses HTTP GET and POST communication for command and control (C2). Network communication is obfuscated with single-byte XOR encoding. Sakula also leverages single-byte XOR encoding to obfuscate various strings and files embedded in the resource section, which are subsequently used for User Account Control (UAC) bypass on both 32 and 64-bit systems. Most samples maintain persistence through a registry Run key, although some samples configure themselves as a service.
