From a defensive perspective, why is it important to minimize users with 'Password Never Expires' and how can you monitor them?

Attackers often target such accounts because they remain valid indefinitely, making them ideal for lateral movement or Domain Penetration - Using MachineAccount to Achieve DCSync. Defenders should regularly enumerate users with this attribute using the same tools (PowerShell, PowerView) and set up monitoring alerts for any changes to `userAccountControl` values that add or remove the 65536 bit.
