It’s an easy way for an adversary to gain initial access if two factor authentication is not properly implemented and more importantly, provides the ability to move laterally in a network and escalate privileges, thus compromising critical data.  Below is a deep dive into the art of passwords, and  how this can play out in both directions.

We call these “selectors,” i.e. the technical attributes of an online entity.
