OmniHide PRO - Just Solve the File Format Problem

File Format
Name OmniHide PRO
Ontology
Released 2010

OmniHide PRO is a Win32 program that hides a file in another file.

It only supports hiding 1 file in another, there is an option for password protection, and there is a free OHP Extractor.

In 'Portable Mode' there is no password protection and if the file being hidden is a zip or rar, it can be recovered by a standard tool like WinZip or WinRar without using OHP.

In 'Secure Mode' a password is required to extract the file.

The trial has several restrictions:

  • Carrier file must be an image between 300x300 and 1440x1440
  • A watermark will be added to the image
  • Can't password protect/encrypt files

Several weaknesses were identified:

  • The filename of the hidden data is stored in plain-text
  • The hidden data is not compressed, making it it easy to determine the size of the embedded data
  • A large quantity of consecutive spaces makes it easy to identify carrier files
