Platform: MSIL

The Common Intermediate Language (formerly known as Microsoft Intermediate Language, or MSIL) is an intermediate language developed by Microsoft for the .NET Framework. CIL code is generated by all Microsoft .NET compilers in Microsoft Visual Studio (Visual Basic .NET, Visual C++, Visual C#, and others).


Malware in this family often is disguised as an image file or as legitimate software. When the user opens the malware, it shows an image or window that does not contain actual content. The malware then extracts a file, contained inside of it, to a temporary folder. This file (in most cases, a keylogger) is added by the malware to the list of programs automatically launched by the operating system during startup.
