Description: Steganographic tool to hide messages in i386 executables Hydan [hI-dn]: Old english, to hide or conceal. Hydan steganographically conceals a message into an application. It exploits redundancy in the i386 instruction set by defining sets of functionally equivalent instructions. It then encodes information in machine code by using the appropriate instructions from each set. Features include: - Application filesize remains unchanged - Message is blowfish encrypted with a user-supplied passphrase before being embedded - Encoding rate: 1/150 Hydan can be used to watermark (fingerprint) code, sign executables, or simply create a covert communication channel.
