[German]With the January 11, 2022 security updates, an issue occurred that caused Windows Server Domain Controllers to enter a cyclic restart loop. I had reported in the blog and Microsoft had already provided special updates in January to fix the problems. Now it seems Microsoft has also posted a corresponding entry on its status page for Windows Server 2022.
[German]It does not seem to be a coincidence: On February 24, 2022, the Russian invasion of Ukraine began – and on that early morning satellite communication for thousands of wind turbines in Europe failed. The background is that communication with the KA-SAT satellite network is disrupted. The wind turbines are still producing electricity, but can no longer be controlled remotely via this satellite link for maintenance. There are indications of a cyber attack.
A small addition to the cyber attack on the Swedish provider Axis Communication (which belongs to Canon). The provider of (IP) security cameras was indeed since 20 February 2022 with many of its services no longer accessible via the Internet. As of Feb. 27, 2022, Axis Communications has published information about what has been (see axis.com confirmed cyber attack (Feb. 23, 2022)).
[German]Occasionally, users of Windows Clients and Windows Server notice an accumulation of error entries in the Event Viewer that seem to indicate a specific problem. An error with the ID 2001 is permanently reported in the Event Viewer. The error text states that "First Counter" in "usbperf\Performance" cannot be read. This indicates that the service "usbhub" has a problem calling it. After the bug came to my attention some time ago, I am preparing the issue as a blog post.

[German]The Russian invasion of Ukraine has had an unexpected effect on cyber security. First there were serious cyberattacks on facilities in Ukraine. Then the Conti ransomware gang claimed responsibility for the Russian government and threatened retaliation for cyberattacks on Russian facilities.

[German]Frequent users of Microsoft Office 2021 and Office 365 have probably already noticed this. The AutoSave function now only saves files from Word, Excel and PowerPoint in the cloud (on OneDrive or SharePoint). A local storage is probably no longer supported.

[German]Windows 11 users complain about Windows Explorer crashes as soon as the Win+X context menu is opened via right-click. The whole thing probably refers to the Insider Preview Windows 11 build 22563.1, but Explorer crashes have been part of users' everyday life since the release of Windows 11. However, there is a workaround that can prevent these crashes with the help of a third-party tool.
[German]The manufacturer of graphics cards and chips, Nvidia, has probably fallen victim to a cyber attack. Currently, the manufacturer is still investigating the details that affected parts of its internal network. According to my information, it was an attack classified as relatively minor, which is currently still being investigated in terms of its impact. The internal operation of Nvidia's IT was affected for two days, and it is currently unclear whether data was leaked. In addition, the Snatch cyber gang is claiming an attack on McDonald in the US.
