🇦🇹 Team Austria placed 8th at #HITCON #CTF as part of the qualifier for #ECSC2025 in Warsaw. Everyone did a fantastic job, so proud of the team. We'll select the 10 final members in the next days, stay tuned! @hitcon.org @tuwien.at @informatics.tuwien.ac.at @cysecwien.bsky.social @hofhackerei.at

Meanwhile, our plane here in Vegas is "too heavy" and we can't take off. They are asking people to leave to reduce the weight. Please tell me this is perfectly normal.

I'm part of the team that discovered the #TapTrap vulnerability. We confirmed that @grapheneos.org has properly fixed it, as detailed on our site taptrap.click Despite a small factual error, it's good to see #GrapheneOS getting some media attention.

Our new Android attack, #TapTrap, is getting media coverage — so here's a quick explainer. It's a new tapjacking technique that exploits Android's UI animations to hijack user taps without requiring any permissions. @beerphilipp.bsky.social will present it at #USENIX Sec'25. 🌐 taptrap.click

It has been an honor to organize the bootcamp for 3 years in a row, and I am proud that it's getting better every time. Thanks to CSA, @cysecwien.bsky.social, ENISA, Joe Pichlmayer, Manuel Reinsperger and the entire team for making this possible. See you all next year ♥️ #CYBER #ECSC2025
