Prof. for networks and security at #JKULinz + dabbling in Android platform security at #Google. This account will mostly carry IT security stuff, occasionally politics and other comedy.

Screeching voice of the minority. I will not cooperate with fascists or nazis - traditional or neo; Austrian, German, US, Russian, or otherwise. I will not help build surveillance and oppression states. Never again.

So, the #Austrian Parliament ignores all expert opinion and ratifies a law to allow #statetrojan #spyware to be bought and used, making the whole population less safe while spending tax money on (non-EU) malware instead of more actual police forces. #Karner has won - at least until #VfGh nullifies it (again) - in getting his legal illusion past the Parliament, even though it can't be technically implemented as written in the law.

I'll need to look more into the missing authentication/authorization issue, as this may require de-trusting D-Trust certificates for multiple use cases, including eIDAS personal digital signatures and the various QWACs (https://www.entrust.com/de/tls-certificate-information-center/d-trust-qwac-eidas-faqs). That is particularly ironic considering the extremely strict BSI Interpretation of some of the eIDAS text parts for use within Germany.
