[German]Small addendum: Oracle's developers have already released Virtualbox version 6.1.26 on July 28, 2020. It is a maintenance update that is supposed to fix bugs of previous versions.
[German]Unknown thread actors are scanning the Internet for Microsoft Exchange servers that are updated to March 2021 and are not protected against the ProxyLogon vulnerability. CERT-Bund warns, and calls for patching. Meanwhile, there are advanced Sigma rules for administrators to defend against attacks.

[German]The timely installation of security updates is a building block to protect Windows systems from the cyber threats of this time. Microsoft therefore once again advertises to its clientele that it implements or achieves a "first-class monthly Windows patch efficiency". Here, in principle, one would nod immediately if it weren't for the teeny-tiny flaw of often unreliable updates, which, unfortunately, are recurrently notable for significant collateral damage.
