Description

Encodes a payload in such a way that the resulting binary blob is both
valid x86 shellcode and a valid bitmap image file (.bmp). The selected
bitmap file to inject into must use the BM (Windows 3.1x/95/NT) header
and the 40-byte Windows 3.1x/NT BITMAPINFOHEADER. Additionally the file
must use either 24 or 32 bits per pixel as the color depth and no
compression. This encoder makes absolutely no effort to remove any
invalid characters.
