This is a PoC that one can hide data inside an Authenticode signed executable without invalidating the signature. It supports compression, encryption and timestamp manipulation, as well as a separat program to extract hidden data. More explanations inside the readme. Discussion follow at; http://reboot.pro/15889/

What's New in Version 1.0.0.6 (See full changelog)

  • 1.0.0.6
  • Added blocking for large files (above 95.000.000 bytes) to prevent large payloads crashing the program.
  • Some more verbose messages and error checking.
  • 1.0.0.5
  • - Fixed bug inside filesystem timestamp manipulation on x64 OS. Turned out some datatypes needed to be changed.
  • - Fixed small bug with the tickbox for keeping timestamps.
  • 1.0.0.4
  • Temporarily deactivated timestamp manipulation on x64 host OS. Problem is caused by how NtQueryInformationFile and NtSetInformationFile are used. Ie DigitalSignatureTweaker will again run on 64-bit host OS.
  • 1.0.0.3
  • New features:
  • - Preserve filesystem timestamps on executable.
  • - Optionally compress data.
  • - Optionally AES256 encrypt the data.
  • - Now with a GUI that shows more verbose information in a lower pane.
  • - Added a custom header in front of hidden data so identification of it is possible.
  • - Added a separate program to extract data from signatures.
