Techopedia Explains Mimikatz

As an application with the ability to store credentials, Mimikatz can be used to steal authentication credentials and create illegitimate privileges. Common types of Mimikatz attacks include pass-the-hash attacks, where hackers get control of hash strings to crack passwords; pass-the-ticket attacks where Mimikatz users abuse Kerberos tickets; and golden or silver ticket attacks, in which the hacker, again through the abuse of Kerberos credentials, gets wide-ranging access to many parts of a system.

Mimikatz is a tool that views and saves Kerberos credentials, so it can be used fraudulently as an access tool. Essentially, the hacker is obtaining authentication credentials and data that will be used to infiltrate systems through the use of this open-source storage application.
