New Tool: jpegdump.py

Filed under: My Software — Didier Stevens @ 0:00

jpegdump.py is a tool I developed to analyze JPEG images. I have used it for a couple of ISC diary entries: Analyzing JPEG files, It is a resume – Part 3 and A strange JPEG file.

This tool reads binary files and parses the JPEG markers inside them:

It can help with corrupted images, here is an example of a JPEG file that was partially overwritten by ransomware:

The partial image starts from marker 3.

With options -f and -c, one can search through binary files with embedded JPEG images, like this Google Chrome process dump:

For more information, take a look at the man page: jpegdump.py -m
