In addition, all ports (if web-server) should be blocked, except port 443 or 80 in some respects (Windows firewall can do that but there are ofcourse better options - PaloAlto is a good one that we use), not sure why the execution policy (if configured properly) would even allow remove exploits like this to penetrate the initial defenses).
netsh advfirewall firewall add rule name="Require Encryption for Inbound TCP/80" protocol=TCP dir=in localport=80 security=authdynenc action=allow
I would also go to "taskschd.msc" and look at the "Task Scheduler Library" to ensure there are no running "PS" scripts. The user can create a script to run to ensure the setting is always set to "Restricted"
This ensures the system is set to restrict executionpolicy or set it to Restricted.
Also, Windows 10 uses Windows Defender Security Center to protect against these types of Attacks, this could have been overlookewell, lessons learned.
