Regin Malware (aka Prax or QWERTY) consists of a trojan and a backdoor that are widely customizable to fit the target. The platform excels at remaining undetected and obfuscating its indicators of compromise. Regin is a modular platform, reminiscent of Flame, Duqu, and Stuxnet. The Regin backdoor is a five stage modular component and each stage after the first is hidden and encrypted. After each successful installation of a stage, the next stage is decrypted and installed. Each piece provides as little information as possible about the total component. If any stage fails then the installation terminates.
