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.
"I need privacy, not because my actions are questionable, but because your judgement and intentions are."

This is currently my primary infosec account in the #Fediverse. It should be #searchable through https://tootfinder.ch. Previous Twitter posts are available in archival form at https://twitterarchive.mayrhofer.eu.org/.
