🇦🇹 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.

After a great run at #defcon33 #CTF, I'm heading to Seattle to attend #USENIX Sec. DM me if you'd like to meet up and join us Thursday at midday for our talk on #TapTrap (track 4) with @beerphilipp.bsky.social ! taptrap.click @lindorfer.in @cysecwien.bsky.social @informatics.tuwien.ac.at

From starting @mhackeroni.bsky.social in 2018 to heading @hofhackerei.at to 9th place at @defcon.bsky.social #CTF finals this year: what a journey. This team is amazing, I couldn't be prouder of all of them and the best is yet to come! 🔥 @cysecwien.bsky.social @tuwien.at @informatics.tuwien.ac.at

First wave of our team (me included) is on the way to @defcon.bsky.social #CTF. Huge thx to the companies and unis backing us, we're extremely grateful. Special shoutout to @tuwien.at for the early support, as well as everyone who joined after. We'll give our best, wish us luck! See you Vegas 🌴🚩

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.

foxnews.com/tech/new-and... > GrapheneOS, a security-focused operating system based on Android, confirmed that its current version is also affected. However, it plans to release a fix in its next update. No, we said that on July 7 and then shipped grapheneos.org/releases#202... fixing it.

ECSC 2025 prep has begun! First Team Austria qualifier wrapped up with 30 participants focusing on #ENOWARS and #DUCTF. Great vibes. Thanks to Ikarus Security for hosting us and everyone who joined! #ECSC2025 @tuwien.at @informatics.tuwien.ac.at @cysecwien.bsky.social

Our #TapTrap attack got covered in @tuwien.at's news! This was such a fun project. Congrats to @beerphilipp.bsky.social on his second first-author paper at a top-tier conference ❤️ We'll present the paper at #USENIX in Seattle on August 14 . Looking forward to catching up with some of you there!

For the second year in a row, @tuwien.at students have nominated our Introduction to Security course among the finalists for the Best Teaching Award! Balancing research, teaching & outreach isn't easy, but we give it our all. 🔗 www.tuwien.at/tu-wien/aktu... CC @informatics.tuwien.ac.at

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
