Want to learn mobile reverse engineering and security analysis on iOS 📱🍎 but can't afford a training since you're a student? We'll do a free edition of day 1+2 of the Nullcon training end of February at TU Darmstadt. Drop me a DM if you're interested. Limited spaces, so better be fast 🔥

OK, so what does fidget mean? What information do you have around you, right now? Take a deeper look. Why is that WiFi AP named XNF998FE? Why is your laptop's serial number XY3327S? How often is that helicopter circling? Why are so many license plates from a particular state with a specific prefix? Look for the lack of entropy that is an encoded signal.

In the early Metasploit days this involved dumping function addresses of DLLs from a literal binder of DVDs. The opcode database and later analysis by folks like skape (matt miller) and spoonm made exploit development much easier as a result.

Scanning the internet is easy. Understanding all the data coming back takes a lifetime. Grab some data dumps and sift through specific protocols and fields. Toss Fiddler at a Windows thick client (or enable HTTP event tracing).

We are flooded in dodgy software, weak numeration, and information leaks. Stop for a bit, breath, pick one, and go deep.

📯 I'm happy to finally be able to release my style plugin to anyone interested!

The plugin helps you write better by pointing out problems in your writing beyond simple spelling mistakes. It's perfect if you use Obsidian for drafting blog posts, job openings, documentation, and other online content.
