IFF Assessment
FOE
This is bad news for defenders as a known VPN vulnerability was not actually fixed, leaving systems potentially exposed.

Defenders should be aware that critical infrastructure relying on Always On VPN may still be vulnerable despite Microsoft's previous advisories. It is crucial to verify the actual status of this fix beyond the October 2026 update and to monitor for subsequent patches and official confirmations.
