Threat Response – Patches available for multiple critical vulnerabilities in Microsoft Windows

14-01-2022

A SAFE DIGITAL JOURNEY

On Tuesday January 11th, Microsoft published a number of patches for multiple security flaws as part of “Patch Tuesday”. Northwave has informed you of this in a previous Treat Response. Microsoft has indicated[1] that this update can cause problems in certain situations, causing domain controllers to go into a boot-loop, IPSEC connections to fail, or servers to respond slowly. The security updates for Windows Server 2012 R2, Windows Server 2019 and Windows Server 2022 have been withdrawn by Microsoft[2].

Our advice regarding these security patches remains the same: When Microsoft makes the new patches available we recommend to install them as soon as possible.

Northwave will monitor developments around these vulnerabilities. When possible, we will add detection rules around these vulnerabilities to the Northwave Detection Platform. We will reach out to you again if there are important updates, including if the threat posed by this activity increases. If you have any questions or require any additional information please reach out to us by phone or email.
