Posted on 2023-12-04 by guenni

Exchange Logo[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.

Windows 11 24H2 and "Windows 12" are proably scheduled for release in 2024

Posted on 2023-12-02 by guenni

Windows[German]Support for Windows 10 will expire for most systems at the end of 2025. Something should therefore happen in 2024 in terms of a "successor". I think it's safe to assume that a feature update for Windows 11 will be released in 24H2 – unless hell freezes over in Redmond because the co-pilot has taken over. Interesting fact: Microsoft also seems to be planning something in the direction of "Managed Service Accounts" to prevent Kerberoasting attacks on network environments. And there has long been a rumor that Microsoft is working internally on a "Windows 12". Rumor has it that manufacturers will receive this Windows as early as 2024 in order to develop devices and possibly launch them on the market in July 2024. The development of this Windows will then move towards more online and more AI features.

Posted on 2023-12-01 by guenni

Windows[German]Since the end of November 2023, users have been reporting that an "HP Smart" printer app has suddenly been installed on their Windows 10 and Windows 11 systems.
