i built an entire x86 CPU emulator in CSS (no javascript)
you can write programs in C, compile them to x86 machine code with GCC, and run them inside CSS
I've recently been digging into Android security and found some interesting stuff, more details on the higher-impact findings will be published later but in the meantime, I'm kicking off the blog with some low-severity findings and will update over time.

I wrote-up how I used o3 to find CVE-2025-37899, a remote zeroday vulnerability in the Linux kernel’s SMB implementation. Link to the blog post below 👇

A common strategy for cryptographic research is to take an old attack and see if you find vulnerable implementations. I took this to a new level with a 379 year old attack: Breaking RSA keys with Fermat's factorization algorithm fermatattack.secvuln.info/
I don't recommend creating Kernel Mode drivers in C#, as it is highly experimental, but its possible.

This is another example, a Driver with memory reading and writing capabilities communication over a hooked function.
