[German]Another note for administrators and users of Jabra headsets (e.g. Jabra Engage 75) who use them in a corporate environment with Microsoft Teams. After there were already problems in connection with Microsoft Teams in December 2022, which were fixed via firmware update, I have now received reports of new problems. I am compiling the information that I have received from users – perhaps someone else is affected.
[German]January 2023 was the scheduled end of support for Windows 7 SP1 and Windows Server 2008 / R2 as part of the Extended Security Update program (ESU). February 2023 is the first month where there should actually be no more security updates. But Microsoft notes in KB4522133 that certain operating systems will receive another year of support with security updates if ESU is booked or Azure is used. Continue reading
[German]It is well known that Microsoft closes user accounts if they have not been used for a long time. It is also well known that phishers try to lure victims with "account closure" mails to sites for harvesting credentials. However, what becomes toxic is a combination where Microsoft itself warns about closing an account due to inactivity, but sends these mails to the wrong senders.

[German]Microsoft has surprisingly released an unscheduled out-of-band update for .NET Framework on January 31, 2023. This should fix problems with XPS documents, which were caused by security updates from December 2022 in .NET Framework – I had reported in the blog. The update must be installed separately. The workarounds issued in December 2022 should then no longer be necessary.

[German]Warning to users of KeePass Password Safe for managing passwords and credentials. The Cyber Emergency Response Team from Belgium (CERT.be) published a warning about KeePass on January 27, 2023. In the default setup, write access to the XML configuration file is possible. This leads to r vulnerability CVE-2023-24055, which could open the way for an attacker to obtain the plaintext passwords by adding an export trigger (Unauthenticated RCE, Information disclosure). However, there are lesser known ways to harden the setup somewhat – whether it is useful is another story. Here is an overview of this topic.
