[German]The desktop app for Microsoft Teams stores authentication tokens as plain text on the Linux, macOS, and Windows platforms. This allows attackers to access accounts using these tokens even if multi-factor authentication (MFA) has been enabled. Customers should rely on Teams web applications or monitor access to MS Teams data through processes, as Microsoft will not close this vulnerability immediately.

[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.

[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.

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.
