Using stegnography, inject text into all imgur image requests by proxying. It stores the contents in redis for performance (why bother re-stegging for a bunch of clients?)
This is an inline script for mitmproxy.
** This requires python 2.7 to my knowledge. mitmproxy seems to need python 2.7 to correctly pip install. **
It's possible I'm wrong, but 1AM me couldn't get this working in CentOS 6 with py2.6
Tested on Fedora 21. Should work in CentOS7, Ubuntu-recent, and anything with python2.7 or higher with relevant image-devel libraries installed.
Doesn't seeem to work on CentOS 6.
Note the requirements.txt:
pip install -r ./requirements.txt
The list of modules:
- mitmproxy
- pillow
- stepic
- Note that you're going to want libjpeg-devel and libpng-devel installed before you install pillow, otherwise you're going to have a bad time
- redis
- redis server listening on localhost
Bring your redis server up, and run
mitmproxy -s mitminject.py
- Track state of injected text (change text to be injected)
- Embed verification (hashing, signing, etc.)
- Squash random exceptions it throws
- un-fuck code style
- Pick a solid state of module versions for requirements.txt (aka get this up in a venv)
