Pixload – Image Payload Creating/Injecting Tools

Pixload - Image Payload Creating/Injecting Tools

 

Set of tools for creating/injecting payload into images.

Useful references for better understanding of pixload and its use-cases:

If you want to encode a payload in such a way that the resulting binary blob is both valid x86 shellcode and a valid image file, I recommend you to look here and here.

SETUP

The following Perl modules are required:

  • GD
  • Image::ExifTool
  • String::CRC32

On Debian-based systems install these packages:

sudo apt install libgd-perl libimage-exiftool-perl libstring-crc32-perl

On OSX please refer to this workaround (thnx 2 @iosdec).

TOOLS
