[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.

[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.

[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.
