Monitors on Dell Thunderbolt docking station not active after reboot

Posted on 2023-03-12 by guenni

[German]Quick note to owners and administrators of Dell docking stations connected to notebooks via Thunderbolt. A reader informed me about problems with the WD22TB4, in connection with Dell notebooks (5530, 5430, 5431).

Windows 10/11: "Mock Folders" as UAC bypass security disaster, leverage Applocker and SRP

Posted on 2023-03-11 by guenni

Windows[German]Windows 10, Windows 11 (and also their server counterparts) contain a huge flaw that may lead to a security disaster. Attackers can create "mock folders" and store malware there. This alows to run malware with administrator rights (without a UAC prompt). Security features like AppLocker or Software Restriction Policies (SRP or SAFER for short) are probably no longer effective either. Is known to security circles, the issue has now come into my radar through an attack.

Cyber attack on logistics service provider – Production at German Airbus site Nordenham partially affected

Posted on 2023-03-10 by guenni

Sicherheit (Pexels, allgemeine Nutzung)[German]Currently (March 8, 2023), production at the Airbus site in Nordenham/Germany seems to be halted (at least in parts). The background to this seems a cyber attack on the logistics service provider (named by my informants as LTS), whose systems probably have been affected by ransomware. Without the systems of this logistics service provider, production at the Airbus plants will probably no longer be possible in the long term. Currently, however, I do not have any confirmation from the logistics service provider. But several sources and Airbus have confirmed the information.

[German]There are signs of a "business change" at WhatsApp, the Meta subsidiary. In the past, WhatsApp didn't care about the EU when it came to data protection and wanted to force users to agree to the transfer of data to Facebook. WhatsApp agrees now to comply with EU regulations, not to forward data to third parties or Facebook for advertising purposes, and to generally become more transparent.
