Security person who likes writing code
Pushed up a few small fixes for boflink. Currently working on some other improvements which should make writing BOFs in higher level languages like C++/Rust/Zig a lot more feasible without needing to add various different compiler/source code tricks

First: Visual Studio Code Visual Studio Code stores it's cached tabs at %APPDATA%\Code\Backups\<guid>\ The untitled temporary tabs will be found in the untitled folder, and each file contains the contents of those tabs

Not sexy things, but they make my day-to-day usage much better. I've seen many people bemoan about Ghidra 's interface. My experience with ANY tool is that things don't change unless the problem is reported to the devs. So reach out and lay out your concerns - they'll respond!

This is a pretty handy trick that I don't commonly see people doing. It's possible to embed a large file in a C/C++ program without needing to create a giant header file for it. Here's a slightly (...very) detailed blog post on it

It's that time of year again everybody! I want to know YOUR thoughts on Mythic! What did you like? What could be improved? What would you like to see next? Why do you or don't you use it? If you could change something, what would it be?

Look, I get it. We've normalized running ads in search results for companies to try to make more money. But I really don't need an ad for buying "linux kernel modules" on Amazon ๐คฆ

Writing Beacon Object Files Without DFR
