Using Credentials

Using Credentials

Every protocol supports using credentials in one form or another. For details on using credentials with a specific protocol, see the appropriate wiki section.

Generally speaking, to use credentials, you can run the following commands:

crackmapexec <protocol> <target(s)> -u username -p password

Note: When using usernames or passwords that contain special symbols, wrap them in single quotes to make your shell interpret them as a string.

Example:

crackmapexec <protocol> <target(s)> -u username -p 'Admin!123@'

Using a credential set from the database

By specifying a credential ID (or multiple credential IDs) with the -id flag CME will automatically pull that credential from the back-end database and use it to authenticate (saves a lot of typing):

crackmapexec <protocol> <target(s)> -id <cred ID(s)>

Brute Forcing & Password Spraying

All protocols support brute-forcing and password spraying. For details on brute-forcing/password spraying with a specific protocol, see the appropriate wiki section.

By specifying a file or multiple values CME will automatically brute-force logins for all targets using the specified protocol:

Examples:

crackmapexec <protocol> <target(s)> -u username1 -p password1 password2

crackmapexec <protocol> <target(s)> -u username1 username2 -p password1

crackmapexec <protocol> <target(s)> -u ~/file_containing_usernames -p ~/file_containing_passwords

crackmapexec <protocol> <target(s)> -u ~/file_containing_usernames -H ~/file_containing_ntlm_hashes
