TChunt-Defeater

TChunt-Defeater is an anti-forensics tool built using Delphi that counters TChunt's ability to detect Truecrypt encrypted containers.

The TChunt works using these four attributes:

  1. No File Header.
  2. (File size % 512) = 0 (Modulo)
  3. Successful X2 and Arithmetic Mean tests on certain bytes.
  4. File size greater than 19KB (Legacy) or 275KB (Current).

My tool counters the second attribute by adding a few NOPS at the end of the file. This is enough to fool TChunt.

See the TChunt-Defeater below in action, step by step.
