Windows 10 Feature Upgrade ends with a non bootable media

Posted on 2021-07-12 by guenni

Windows[German]Today another blog post from the category "Windows 10, the mysterious update experience". A blog reader recently drew my attention to a new "upgrade experience" (that's what Microsoft calls it). The Experience is described quite quickly: The unsuspecting user receives a prompt to install a feature update and then ends up with an unbootable system because no boot media was found. At the same time, the "system-reserved" partition was suddenly given a drive letter. Maybe a single case.

Do IoT devices with built-in "radio chips" endanger IT security?

Posted on 2021-07-11 by guenni

Sicherheit (Pexels, allgemeine Nutzung)[German]Interesting aspect I stumbled upon recently. It's about the question of how Internet of Things (IoT) devices threaten IT security. Because in addition to often serious vulnerabilities in their firmware as well as lack of updates after a short time, there is another problem area. Many devices have built-in WLAN or Bluetooth chips without users being made aware of this when they are sold. The next security issue is emerging.

Follow-up to the Kaseya supply chain attack

Posted on 2021-07-10 by guenni

Sicherheit (Pexels, allgemeine Nutzung)[German]At the beginning of July 2021, there was a supply chain attack on Kaseya VSA, a remote management and monitoring (RMM) software, so malware was delivered. As a result, the REvil Ransomware group's encryption Trojan struck, encrypting the IT systems of approximately 1,500 companies worldwide. Gradually, more details are becoming known. For example, the vulnerability exploited for the attack was reported to Kaseya in April 2021 – and a vulnerability known since 2015 is still open in their management software.

Windows 10: Microsoft fixes Zebra & Dymo printer issues caused by update (e.g. KB5004945) via KIR

Posted on 2021-07-09 by guenni

Windows[German]After installing updates (e.g. KB5004945, KB5003690, KB5004760), some decicated to close the vulnerabilities in the print spooler service, systems with label printers from Zebra and Dymo experienced printing issues – printing is no longer possible. Until now, the only option was to uninstall the relevant update or try to print directly via USB. Based on the feedback, however, Microsoft has now responded and provided a fix to correct this problem caused by several updates via the KIR function available in Windows 10 from version 2004 and later.

Changes and ambiguities in driver updates via WSUS; is Windows 10 bypassing Updates via WSUS?

Posted on 2021-07-09 by guenni

Update[German]In today's blog post, I'll summarize two things that German blog reader Markus K. pointed out to me by mail. Possibly there are changes in driver updates via WSUS, at least there are and ambiguities. Once he suddenly appears on Dell systems password prompts to clients when a firmware is to be installed. But there are other oddities, such as missing reloading of drivers after an activation. And then there is the suspicion that Windows 10 gets the updates directly past WSUS, from the Microsoft update servers, no matter what the administrator has set in group policies.

The Chaos PrintNightmare Emergency Update (July 6/7, 2021)

Posted on 2021-07-08 by guenni

[German]Microsoft has released out-of-band security updates for the PrintNightmare vulnerability (CVE-2021-1675) in the Windows Print Spooler service. But these updates seem to end in chaos – it reminds me on the Printer-Gate in March 2021, where Microsoft had to release a series of update fixes to close a printer vulnerability but still allow printing. I'll summarize a few points outside of Microsoft's documentation in this blog post. These range from the fact that the updates don't close the vulnerabilities, to installation issues and problems with Zebra label printers subsequently refusing to print.
