A Defcon 27 workshop repository with 8 hands-on labs teaching how to write custom backdoor payloads in C# targeting C2 frameworks like Metasploit, Empire, and Cobalt Strike. It covers techniques such as shellcode injection, process hollowing, DLL injection, and antivirus bypass from both attack and defense perspectives.

Use cases

  • learn to write custom C2 payloads in C#
  • understand shellcode injection techniques
  • study process hollowing and DLL injection
  • learn antivirus evasion techniques
  • red team training on payload development
  • understand offensive techniques from a defense perspective

When to choose

  • you want hands-on labs for offensive .NET/C# development
  • you're preparing for red team work or security certifications
  • you want to understand Windows injection and evasion techniques

When to avoid

  • you need production-ready offensive tooling rather than educational labs
  • you're looking for defensive-only tooling
  • you have no interest in Windows/.NET environments
