13. May 2022 - Service Announcement Actively exploited vulnerabilities in various Windows versions - Install updates now
DFN-CERT has issued a report (DFN-CERT-2022-1045) pointing out several security vulnerabilities in Windows and Windows server versions that are currently being actively exploited by hackers. For example, individual vulnerabilities can be exploited to remotely execute malicious code.
Therefore, we recommend that you immediately install any and all Windows updates that are currently available. This applies to both servers and desktop PCs running Windows. Microsoft has already made various security updates available on the current Patch Tuesday.
On Windows desktop, the update installation is usually performed automatically. If you want to manually check whether updates are available, press the Windows key and type "updates". Then open the menu item "Check for updates". In the window that appears, possible updates will be displayed and can be installed manually.
