    Attacker's goals: Use a compromised user account which has not been used for a long while, and therefore is less likely to be noticed.
    Investigative actions: Confirm that the activity is benign (e.g. the user returned from a long leave of absence). See whether there are other abnormal actions done by the user (e.g. files\commands\other logins). Check if the user initiated other logins aside from a VPN login. Check whether you have issues with your Cloud Identity Engine failing to sync data from Active Directory.
