Brute Force: Credential Stuffing

Threat Actors may use credentials obtained from breach dumps of unrelated accounts to gain access to target accounts through credential overlap.

The information may be useful to Threat Actors attempting to compromise accounts by taking advantage of the tendency for users to use the same passwords across personal and business accounts.
