The goal of Truehunter is to detect TrueCrypt containers using a fast and memory efficient approach. It was designed as a PoC some time ago as I couldn't find any open source tool with the same functionality.
Just use with Python 2.7, it does not need any additional libraries.
usage: truehunter.py [-h] [-D HEADERSFILE] [-m MINSIZE] [-M MAXSIZE] [-R MAXHEADER] [-f] [-o OUTPUTFILE] LOCATION Checks for file size, unknown header, and entropy of files to determine if they are encrypted containers. positional arguments: LOCATION Drive or directory to scan. optional arguments: -h, --help show this help message and exit. -D HEADERSFILE, --database HEADERSFILE Headers database file, default headers.db -m MINSIZE, --minsize MINSIZE Minimum file size in Kb, default 1Mb. -M MAXSIZE, --maxsize MAXSIZE Maximum file size in Kb, default 100Mb. -R MAXHEADER, --repeatHeader MAXHEADER Discard files with unknown headers repeated more than N times, default 3. -f, --fast Do not calculate entropy. -o OUTPUTFILE, --outputfile OUTPUTFILE Scan results file name, default scan_results.csv
