Tofu is a modular tool for hacking offline Windows filesystems and bypassing login screens. Can do hashdumps, OSK-Backdoors, user enumeration and more.
When a Windows machine is shut down, unless it has Bitlocker or another encryption service enabled, it’s storage device contains everything stored on the device as if it was unlocked. This means that you can boot from an operating system on a bootable USB and access it’s files – or even just connect the filesystem to another computer.
This tool helps for when you can access the Windows filesystem from Linux (using one of the mentioned methods); it has utilities that can dump NTLM password hashes, list users, install backdoors to spawn an elevated command prompt at the login screen and more.
Because tofu works on modules, it can be expanded for different purposes. See the ‘modules’ section for examples.
Current Modules:
1. hashdump.py – Dumps NTLM hashes from the target Windows filesystem
2. osk_backdoor.py – Backdoor osk.exe to bypass the login; also includes an ‘unbackdoor’ module
3. list_users.py – List the users with a profile on the Windows filesystem
4. chrome.py – Dump chrome history and login data of all users on the Windows filesystem
5. get_dpapi_masterkeys.py – Dump DPAPI master keys from the Windows filesystem
6. enum_unattend.py – Enumerate unattend files
7. memory_strings.py – Search through the memory of the computer to find data
8. startup.py – Inject a program into a user’s startup directory
9. wifi.py – Get Wi-Fi passwords with DPAPI
‘list’ : List all storage devices at /dev/ with a format of MSDOS, NTFS or -FVE-FS- (BITLOCKER) ; This will load the drive paths into memory
‘usedrive’ : Set the drive to use; can use numbers assigned from the ‘list’ command
‘modules’ : List modules ; This will load the module names into memory, so you need to run this command before selecting a module
‘use’ : Use the selected module
