NTFSTool – Forensics Tool For NTFS (Parser, MTF, Bitlocker, Deleted Files)
NTFSTool is a forensic tool focused on NTFS volumes. It supports reading partition info (mbr, partition table, vbr) but also information on bitlocker encrypted volume, EFS encrypted files and more.
See below for some examples of the features!
Features
Forensics
NTFSTool displays the complete structure of master boot record, volume boot record, partition table and MFT file record. It is also possible to dump any file (even $mft or SAM) or parse USN journals, LogFile including streams from Alternate Data Stream (ADS). The undelete command will search for any file record marked as “not in use” and allow you to retrieve the file (or part of the file if it was already rewritten). It support input from image file or live disk but you can also use tools like OSFMount to mount your disk image. Sparse and compressed files are also supported.
Bitlocker support
For bitlocked partition, it can display FVE records, check a password and key (bek, password, recovery key), extract VMK and FVEK. There is no bruteforce feature because GPU-based cracking is better (see Bitcracker and Hashcat) but you can get the hash for these tools.
EFS support
In the current version, masterkeys, private keys and certificates can be listed, displayed and decrypted using needed inputs (SID, password). Certificates with private keys can be exported using the backup command. Reinmport the backup on another machine to be able to read your encrypted file again!

Decryption of EFS encrypted files is coming!
Shell
There is a limited shell with few commands (exit, cd, ls, cat, pwd, cp).
Help & Examples
Help command displays description and examples for each command. Options can be entered as decimal or hex number with “0x” prefix (ex: inode).

Build
Vcpkg is the best way to install required third-party libs.
Install vcpkg as described here: vcpkg#getting-started
git clone https://github.com/microsoft/vcpkg
.vcpkgbootstrap-vcpkg.bat
Integrate it to your VisualStudio env:
vcpkg integrate install
At build time, VisualStudio will detect the vcpkg.json file and install required packages automatically.
Current third-party libs:
- openssl: OpenSSL is an open source project that provides a robust, commercial-grade, and full-featured toolkit for the Transport Layer Security (TLS) and Secure Sockets Layer (SSL) protocols.
- nlohmann-json: JSON for Modern C++
- distorm: Powerful Disassembler Library For x86/AMD64
- cppcoro: A library of C++ coroutine abstractions for the coroutines TS.
