File Format
Name Steganography
Ontology

Steganography is a class of encryption in which the very fact that information exists is obscured. For example, an innocent-looking PNG image could contain a secret message encoded in its seemingly-random least-significant bits. Assuming the algorithm is sufficiently secure, it would be impossible to know whether the message exists or not, unless you know the secret key.

    • StegoCommand: Statistical and structural anomalies, data appending and prepending, misplaced or suspect text or binary
  • StegoSuit - perform ELA (Error Level Analysis), String, Threshold, Edge and Metadata analysis of any image
  • Stegosuite Analysis - chi square, LSB visualization, histogram (neighborhood, pixels difference, pov), sorted color table attack
  • StegSolve
