[German]A small note to administrators and developers who are responsible for the use of Microsoft Teams and use a data export via Microsoft Graph from Microsoft Teams.

[German]A 0-day vulnerability CVE-2022-30190 (Follina) in Windows has been known since the end of May 2022. Yesterday, a tip from a security researcher came to my attention, who has not yet found any active exploitation via manipulated Office documents. On the other hand, Proofpoint reports that they have just stopped a phishing campaign attacking customers at EU and US government agencies. State actors are suspected to be behind the action. An attack was also observed in the South Pacific, originating from servers in Palau. In the process, a digital certificate from a company was misused for signing. The CERT-UA also warns of attacks on government targets in Ukraine. Time for a brief stocktake around the exploitation of Follina.

[German]Another small addendum (almost a warning) to owners of Microsoft accounts. It seems that there was a bug in the account management that caused the account in question to be locked when its owner tried to read in so-called Reward Points. Then the stress started for some people, because they connected their digital life to the Microsoft account and couldn't access their mails or their files stored on OneDrive anymore. Skyping or other applications like Office 365 as well as Windows 8.1/10/11 may also be affected. However, the bug has already been fixed by Microsoft on June 3, 2022 – but affected users can run after Microsoft to get the account back.
