VPN login by a dormant user
A dormant user logged on to a VPN service after having been unused for a month or longer. This may indicate the account is misused by an attacker.

ATT&CK tactics: Defense Evasion (TA0005)
ATT&CK techniques: Valid Accounts: Domain Accounts (T1078.002)
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.
