I have released the first half of "Binary Exploitation 101", a beginner-friendly guide to binary exploitation. You can learn from classic buffer overflow to ret2dlresolve through CTF-like challenges. I am working on the second half now. Stay tuned🔥

Back to working on NomNom, my ransomware PoC. Currently working on Implementing exfiltrations of keys to a C2 server. The keys were originally saved in a file on disk which isn't the best.
Like always, I have a lot of debugging to do :-)
Doing a bit of learning on the Native Windows API. Thinking of using it in my Ransomware PoC as it’s potentially stealthier and better for evading AVs and EDRs

Implemented a method in my custom C++ c2 to fetch already stored keys :-). This should be enough for me to continue building my Ransomware PoC
I will however be implementing some new functionality soon.
Implementing some anti-debugging techniques in my Ransomware PoC.
Instead of using the usual 'IsDebuggerPresent()' which tends to be very suspicious, I implemented my own function. Learning about Windows Internals is definitely paying off :-)
Back to building a light weight C2 for my projects. This time, I'm using Crow, a C++ framework for creating HTTP or Websocket web services. It's really similar to Python's Flask.
