Description(Kaspersky) The final stage is a formerly unknown modular backdoor that we dubbed Samurai, due to a constant keyword used inside an important dictionary used by the malware to share data between its modules.

The library was developed in C# and uses the .NET HTTPListener class to receive and handle HTTP POST requests, looking for specially crafted requests that carry encrypted C# source code issued by the attackers. These programs will be in turn compiled and executed during runtime.
