StegoStick - Just Solve the File Format Problem

File Format
Name StegoStick
Ontology
Released 2008

StegoStick by P.V. Uma Mahesh and V. Santhosh Kumar is an open source steganography program that allows the hiding of a file in a BMP, WAV, AVI, or MPEG and the embedding of any file within another.

It has 3 different encoders:

  • BMP - uses standard LSB hiding. It will convert JPG or GIF to BMP
  • Media (WAV, AVI, MPEG) - semi-generic LSB algorithm. Unfortunately it uses the LSB of every byte, so if a chunk is more than 8 bits (like a 16-bit WAV), changes aren't limited to the LSB, degrading the output
  • Other - generic file appending

It requires a password and offers DES, TripleDES, RSA and 'default' encryption

One weakness is that it is possible to determine what filetype was embedded
