Brief information for users of Veeam products. Two readers have pointed out to me that the manufacturer has updated its product portfolio as of December 5, 2023 (thanks for that). The updates range from Veeam Backup & Replication to Veeam One and special solutions for Linux distributions.
[German]What Microsoft has just announced comes as a surprise. After the official Windows 10 support ends in October 2025, Redmond will continue to provide paid security updates for a further three years. And an innovation that has never been seen before: Private users can also buy corresponding ESU licenses to be able to operate their Windows 10 systems until the end of 2028. Below I provide an overview of the situation and also outline alternatives.
[English]A little tip for Exchange Online administrators. What to do if issues occur when processing mails due to mail flow rules. The options for tenant administrators were previously limited, and Microsoft support often had to be called. Microsoft has now reacted and is trying to support administrators of Exchange Online tenants with a corresponding PowerShell cmdlet "Test Message" to diagnose the use of Exchange Transport Rules (ETRs).
[German]Short alert to clarify who is affected and to warn that something is up. At the moment there seem to be massive problems with Windows Server and especially with RDS Server when ESET Server Security is installed. The systems with Windows Server simply crash when the relevant ESET Server Security is installed. Here is some information as far as I have it.
[English]Since the end of November 2023, users have reported that an "HP Smart" printer app has suddenly been installed on their systems with Windows 10 and Windows 11. In addition, the entries for printers (icon, name) may have changed under Windows. Microsoft has now confirmed the facts as of December 4, 2023 and has set about analyzing the problem. Here is a brief overview of the status.

[German]Microsoft has released the optional cumulative (preview) update KB5032288 for Windows 11 version 22H2 and 23H2 on December 4, 2023. Looks like this preview update was not ready in November 2023 and is now available in December. The preview update brings a number of fixes and rolls out the preview for Copilot again.
[German]CVE-2023-23397 is a vulnerability in Microsoft Outlook that could be exploited in conjunction with Microsoft Exchange servers, which was closed with security updates in March 2023. Microsoft has now identified an attacker based in Russia who is actively exploiting CVE-2023-23397 to gain unauthorized access to email accounts in Exchange servers. This can then be used for NTLM relay attacks against other services. The Russian attacker is referred to by Microsoft as Forest Blizzard (STRONTIUM, APT28, FANCYBEAR).
In September 2023 there was the "Nullcon Security Conference" in Goa. I was invited this year, but unfortunately (as with so many other conferences) I was unable to attend (which is better from an environmental point of view). But the organizers kept their word and informed me afterwards at the end of November 2023 that the recordings of the lectures are now online. Interested readers can find the slides of the presentations on this website.
[German]Looks like we're heading for the next cyberattack disaster. Network scans by security researchers have found around 20,000 Microsoft Exchange servers that are accessible via the internet and vulnerable to remote code attacks. The Exchange servers are located in Asia, Europe and the USA and can no longer be patched as they have reached the end of their life cycle and have fallen out of support. A worthwhile target for cyber attackers, who can no longer keep up as quickly as security gaps grow on the Internet.
