NTFSTool is a forensic tool focused on NTFS volumes. It supports reading partition info (MBR, partition table, VBR) but also information on Master File Table, Bitlocker encrypted volume, EFS encrypted files, USN journal and more.
Download the latest binaries on AppVeyor.
See below for some examples of the features!
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 and analyze USN journal, LogFile including streams from Alternate Data Stream (ADS). $MFT can be dumped as csv or json with Zone.Identifier parsing to quickly identify downloaded files. 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, live disk or virtual like VeraCrypt and TrueCrypt, but you can also use tools like OSFMount to mount your disk image. Sparse and compressed files (lznt1, xpress) are also supported.
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.
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!
Or you can use the efs.decrypt command to decrypt a file using the backed-up key.
More information on Mimikatz Wiki
USN journal records can be analyzed using custom rules to detect suspicious programs and actions but also to have an overview of the journal (% of file deleted, created ...)
Default rules: Rules/default.json
{
"id": "lsass-dump",
"description": "Dumped LSASS.exe process.",
"severity": "high",
"rule": {
"filename": "lsass(\\.(dmp|dump))?"
}
}
See an example of run here: usn.analyze
There is a limited shell with few commands (exit, cd, ls, cat, pwd, cp, quit, rec).
Command rec shows the MFT record details.
Help command displays description and examples for each command.
Options can be entered as decimal or hex number with "0x" prefix (ex: inode).
