Microsoft updates mitigation guidance for Windows BitLocker security feature bypass vulnerability with a NEW script!

The updated guidance replaces previously documented manual mitigation steps with a script that helps reduce exposure while a future security update is developed to address this vulnerability.

The Windows versions below are affected:

- Windows 11 26H1
- Windows 11 25H2
- Windows 11 24H2
- Windows Server 2025

Windows devices that use BitLocker may be exposed to this vulnerability if mitigations are not applied.

Organizational environments that previously implemented the documented manual mitigation steps do not need to take additional action, as the script only simplifies deployment of the existing mitigation.

Authenticated Received Chain (ARC) Protocol is being retired!

ARC was introduced in 2019 as an "Experimental" protocol to preserve email authentication results across intermediaries (mailing lists, forwarding rules, security appliances, and so on).

After seven years of real-world use, the experiment is now officially coming to an END.

A new document calls for a conclusion to the experiment defined by "The Authenticated Received Chain (ARC) Protocol" [RFC8617], and recommends that ARC no longer be deployed or relied upon between disparate senders and receivers.

The document summarizes what ARC set out to do, reports on operational experience, and explains how the experience gained during the experiment is being incorporated into the proposed DKIM2 work as the successor to DomainKeys Identified Mail [RFC6376].

To avoid any future confusion, it is therefore requested that ARC [RFC8617] be reclassified as "Historic".
