🔍 A DLL isn’t a standalone file — it has no main function like an EXE. That’s why we need tools like WinDbg + SOS to uncover where execution really begins. In this week’s drop, we show you how. youtu.be/MsijfXAu3rA?si… #ReverseEngineering #dotnet #MalwareAnalysis #HackDef #dll

Happy to support new talents! Welcome Vinny to the academy!

Congratulations to Vinny, winner of the Certified Crimeware Defender (CCWD) training from @hackdef! A huge thank you to Hack Defender Academy for supporting the community through this training opportunity. Let the hacking begin! #CCWD #CyberSecurity #CyberTraining #CTF



When dnSpy can’t help, you need SOS — not the distress call, but Son of Strike. A WinDbg plugin for .NET malware that’s been around 8+ years yet still barely documented. Researchers use it when obfuscation wins. 🎯 youtu.be/GLH8zRKdtRs?si… #HackDef #Dotnet #ReverseEngineering
