Much broken crypto, one common thread: bespoke, ill-designed cryptographic protocols. Matrix, Mega, Threema, Telegram: secure primitives are not enough in complex applications. The new mantra shall be "don't roll your own protocol".

We (@winterdeaf @kientuong114 and I) took a deep dive on Threema, a Swiss-made secure messaging app. We found 6 new cryptographic vulnerabilities. Full paper at breakingthe3ma.app; mini-thread follows. #threema

I would like to thank the chairs for letting us use heart emojis in the paper title. I think this is a very important step forward for academia and research. Can't wait to use "👀" for related work and "🤨" for limitations on the next one
Are you working with stubborn aarch64 code? Check out @cyan_pencil's upcoming @USENIXSecurity #SEC23 paper on efficiently rewriting ARM binaries. Insight: using heuristics for optimization on a safe baseline is key! nebelwelt.net/files/23SEC3.p… Comments welcome!

No one sees ChatGPT for the first time and thinks "just some n-gram correlations" or "no real knowledge inside". Those unintuitive beliefs trickle down from some experts, who should know better than to teach their controversial theories as established fact: 🧵 (1/12)

In early 2022 I started working with Kenny and Matteo on analyzing Threema, the messenger used by 🇨🇭govt, army and 🇩🇪 chancellor. Happy to say that the disclosure period is over and results are out! Fun vulnerabilities included :) Check out our website: breakingthe3ma.app

"Why?" "NO REASON!" [pointedly not looking at Threema]

I’d like to borrow 8192 cores for a week. Anyone out there got some spare compute lying around to help out with a cool research project?

If your main product uses cryptography, at the very least have a crypto PhD on your team!

Great day for rap-based cryptography! @kientuong114 and Matilda burst onto the scene with some mellow key wrapping rap (youtube.com/watch?v=yh45UpVQ…). @KhanhCrypto drops another stunner, with big names such as @cronokirby, @FouotsaB, and yours truly (youtube.com/watch?v=1z362xyQ…) 🔥💣🔥💣
