Here is how OpenAI’s CISO fumbled the situation (in my personal opinion) 🧵 1/X

The end of flow state You wake up, excited for the day to start. You have a feature idea you are looking forward to implement. You make your coffee. Sit in front of the laptop. Put on that techno set you love. The house is empty for the next 8 hours. No one can interrupt you. You open your IDE and begin typing. Soon, hours pass in minutes. Everything makes sense. And before you know it, it’s the end of the day. You’re looking at today’s work and are content. You’re energised. Because you created something you enjoy. Fast forward. No more. You start a new day with an open IDE. But, instead of pressing those keyboard buttons, you’re staring at a orange text. “Discombulating” “Wombanizing” Minutes feels like hours. Nothing makes sense. And before you know it, it’s the end of the day. You’re tired. Your brain hurts. It feels like you just finished a ton of meetings. But, at least you shipped 1,000 lines of code, right? You should be proud. But, the only thing you feel is hollow. Did you create? Or did someone else? That magical feeling from years ago, where did it go? Rest in peace, flow state. You were dear to me.

Did you know macOS binaries can run on iOS? It needs rewriting architecture information and adjusting library paths. I automated this, including DYLD shared cache library extraction and replacement, allowing many macOS command line tools to run on iOS. github.com/mowisec/macos-to-…

hottake: connect to literally any wifi network at defcon you want, it doesn’t matter. It’s not 2010. If someone throws RCE at your fully patched MacBook you earned that shit

[1/3] It's common to get a ParcelFileDescriptor pointing to a directory through an Android ContentProvider. But can you actually turn that into a directory listing?

Because we train LLMs on lots of movies and books about AI uprising, or articles and tweets about dystopian fears of AI, we might be causing the threat ourselves 🤔

Our second blog post is out here: bugscale.ch/blog/here-we-go-… ! We managed to install arbitrary APKs on the Samsung Galaxy S25 from an app without install permissions. For this, @SachaKozma did most of the work, but it was great looking into Samsung's cloud gaming component with him
