Stegseek is a lightning fast steghide cracker that can be used to extract hidden data from files. It is built as a fork of the original steghide project.
Uses
Stegseek can also be used to extract steghide metadata without a password, which can be used to test whether a file contains steghide data.
Cracking
The most important feature of stegseek is wordlist cracking. StegSeek uses a wordlist that you provide to crack hidden data in the file:
stegseek [stegofile.jpg] [wordlist.txt]
This mode will simply try all passwords in the provided wordlist against the provided stegofile.
