Ready to build your first piece of "malware" for your red teaming engagements? In this video, we'll develop a simple but effective C++ program that creates a reverse shell from a Windows x64 machine back to your Kali Linux box.
We'll cover the full process, from generating the payload with MSFvenom to writing the C++ code in Visual Studio that executes it. I'll explain why this method is so common and how it bypasses a key Windows security feature, DEP (Data Execution Prevention).
We'll break down the exact four Windows API functions you need to know:
1. VirtualAlloc: To ask the OS for executable memory.
2. RtlCopyMemory: To copy our shellcode into that new memory.
3. CreateThread: To "hire a worker" to run our code.
4. WaitForSingleObject: To keep our program alive so the shell doesn't die.
⚠️ *This video is for educational purposes and authorized red teaming engagements ONLY.* All actions are performed in a controlled lab environment with security features (Defender, Firewall) disabled. Do not use these techniques for illegal activities.
