1- Open your FTP panel, after login to https://it.altervista.org/
2- Create new file with name "exploit.php" and save.
3- Open the file "exploit.php" e insert this code => "http://nullsite.altervista.org/nopaste/?viewpaste=20" later save and close.
4- launch the file "exploit.php" wait 6 seconds and close page.

Now inside your FTP (site's files)
you will be able to see a file with unrecognized characters that you will not be able to delete manually and even with an FTP Client.

thanks to me.
