Description

A user failed to log in to multiple hosts it never accessed before in a short amount of time. This may indicate the account is compromised and an attacker is probing for a host it can access with those credentials.

Attacker's Goals

Gain access to hosts by using stolen user-account credentials.

Investigative actions

Check if the user account was compromised, and which resources it could access.
