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.
