The worst bugs are the ones where the code mostly works. Low-level AI coding is so complex that I (an the AI that I write code with), produce an annoying number of them.

In this blog post, I explain how I was able to create a PowerShell console in C/C++, and disable all its security features (AMSI, logging, transcription, execution policy, CLM) in doing so. 💪

I’m very excited to announce that we at V8 Security have finally published our first version of Fuzzilli that understands Wasm!
Go check it out at https://github.com/googleprojectzero/fuzzilli.
While we still have a way to go in improving it, we think it shows a promising approach!

Binary diff'ing is hard. But it's super powerful to apply markup from previous reverse engineering efforts to a new binary.

Binary Ninja is switching up how they match function signatures with WARP.

Stability in AFL++/LibAFL is quantified by the percentage of edges in the target that are considered “stable”. If repeatedly sending identical inputs results in the data traversing the same path through the target each time, then the stability is determined to be 100%.

Microsoft just released a tool that lets you convert Office files to Markdown. Never thought I'd see the day.

Google also added Markdown export to Google Docs a few months ago.
