W64.Shruggle.1318 is a direct-action file infector, similar to W64.Rugrat.3344, that infects AMD64 Windows Portable Executable (PE) files. It is a fairly simple proof-of-concept virus; however, it is the first known virus to attack 64-bit Windows executables on AMD64 systems. The virus is written in AMD64 assembly code.
