[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).

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
