[German] U.S. ride share service provider Uber appears to have been the victim of a hack, with an 18-year-old penetrating the provider's system. Uber employees initially thought the whole thing was a joke. The hacker claims to have entered the Uber system "for fun", but then probably found a PowerShell script on a share, which contained administrator credentials. And now the hacker is probably an administrator of the Uber IT systems.
[German]Hardware and software products are increasingly subject to successful cyberattacks, resulting in an estimated annual cost of €5.5 trillion from cybercrime by 2021. The European Union therefore presented a draft Cyber Resilience Act on September 15, 2022.

[German]Small note to the blog readership. The developer of the browser add-in "I don't care about cookies" has just announced that he has sold his product to AVAST. I don't begrudge Daniel Kladnik this sale, but I have some thoughts of my own in the back of my mind about whether the extension is really in good hands with AVAST. Here is some information about this topic.
[German]There is a serious vulnerability (backdoor) in the firmware of power delivery units from the US manufacturer Networx. In older versions (prior to version 2.0.2a ), the firmware does not perform authentication, i.e. it is possible to switch off the power delivery unit (PDU) via the network. This is deadly if these units are used for power supply in data centers and are accessible via internet. After a reader's tip, I contacted the manufacturer and GErman CERT Alliance about this. After much back and forth, there is now a working update. Below I disclose the details. Operators should urgently isolate the PDUs and install the firmware update promptly.

[German]Sort September 2022 patchday recap. It looks like the cumulative (security) update KB5017308 released on September 13, 2022 for Windows 10 comes with collateral damage. I have received several reports from readers that following the update installation, creating or copying files via GPO or creating GPO settings files no longer works.

As of September 13, 2022, Microsoft has released a few more updates for the .NET Framework. Bolko pointed it out here (thanks for that). Update KB5017529 is the Security and Quality Rollup for .NET Framework 3.5.1, 4.6.2, 4.7, 4.7.1, 4.7.2, 4.8 for Windows 7 SP1 and Windows Server 2008 R2 SP1 and includes KB5017036 (.NET 4.8) and KB5016368 (.NET 4.7).

[German]A recent lawsuit filed by the Arizona Attorney General against technology company Google shows that the company continues to track users who have declined location tracking anyway. Thus, IP addresses of Google users served to obtain accurate location information and then used for Google services. On October 24, 2022, Arizona's lawsuit against Google is scheduled to be heard – and I think the EU will be watching closely as well, since Google is in the sights of EU antitrust watchdogs for various competition complaints and there are also GDPR complaints from consumer protection organizations.
