CredNinja is a tool to quickly test credential validity of dumped credentials (or hashes) across an entire network or domain very efficiently.
At the core of it, you provide it with a list of credentials you have dumped (or hashes, it can pass-the-hash) and a list of systems on the domain (the author suggests scanning for port 445 first, or you can use “–scan”). It will tell you if the credentials you dumped are valid on the domain, and if you have local administrator access to a host.

Required Arguments: -a accounts_to_test.txt, --accounts accounts_to_test.txt A word or file of user credentials to test. Usernames are accepted in the form of "DOMAIN\USERNAME:PASSWORD" -s systems_to_test.txt, --servers systems_to_test.txt A word or file of servers to test against. This can be a single system, a filename containing a list of systems, a gnmap file, or IP addresses in cidr notation. Each credential will be tested against each of these servers by attempting to browse C$ via SMB Optional Arguments: -t THREADS, --threads THREADS Number of threads to use. Defaults to 10 --ntlm Treat the passwords as NTLM hashes and attempt to pass-the-hash! --valid Only print valid/local admin credentials --invalid Only print invalid credentials -o OUTPUT, --output OUTPUT Print results to a file -p PASSDELIMITER, --passdelimiter PASSDELIMITER Change the delimiter between the account username and password. Defaults to ":" --delay SECONDS %JITTER Delay each request per thread by specified seconds with jitter (example: --delay 20 10, 20 second delay with 10% jitter) --timeout TIMEOUT Amount of seconds wait for data before timing out. Default is 15 seconds --stripe Only test one credential on one host to avoid spamming a single system with multiple login attempts (used to check validity of credentials). This will randomly select hosts from the provided host file. --scan Perform a quick check to see port 445 is available on the host before queueing it up to be processed --scan-timeout SCAN_TIMEOUT Sets the timeout for the scan specified by --scan argument. Default of 2 seconds -h, --help Get help about this script's usage --no-color Turns off output color. Written file is always colorless Additional Information Retrieval: --os Display the OS of the system if available (no extra request is being sent) --domain Display the primary domain of the system if available (no extra request is being sent) --users List the users that have logged in to the system in the last 6 months (requires LOCAL ADMIN). Returns usernames with the number of days since their home directory was changed. This sends one extra request to each host --users-time USERS_TIME Modifies --users to search for users that have logged in within the last supplied amount of days (default 100 days) |
The tool really shines on large networks where it can parse a large amount of hosts quite quickly.
It is intended to be run on Kali Linux
