Cornelia
From Bibliotheca Anonoma
Due to the famous Cornelia malware, and the constant influx of files being passed around on 4chan, certain images from 4chan, or anywhere else may contain hidden data, even rar archives.
Use this script to investigate if any of your images have something more than meets the eye. However, you will also have to guess the filetype of the hidden data, though that should be easy.
