View Full Version : Denial Of Service Method

I know alot of you are interested in DoS so I figured Id do a tutorial explaining a method thats exceedingly hard to recognize and stop.


Of course, the method shown in the video isnt a DDOS (DISTRIBUTED Denial of Service) as it was only made to show how something as simple as this can be used as an attack tool. Obviously the more distributed it is (ie. the more PCs running it) the greater its effectiveness.

Also, there are MANY ways to launch a DoS attack, for example filling up simultaneous maxconnects, packet crafting, bandwidth attacks, etc.

This was created to show a particular attack method and help admins recognize and therefore be able to defend against such methods, NOT to go and attack people.

I love this tutorial, it's great, and really simple to execute.

Thanks for this:D

Very easy to use, thanks!

It worked very well.;)

My alternative method (for *nix):


for (( i=0; i<=*000; i+=* )); do
wget http://www.website.com/big_file.zip
rm big_file.zip

Or, you can make a program that continually makes HTTP requests to the server directly at the socket level. Maybe if they were HEAD requests, you'd be able to destroy them even more effectively if you were lacking in download speed, since they have to deal with the request, but not send you the file/page you requested.

I'm not leet enough for any direct IP-level attacks, but that's where the most potent attacks would be found in my opinion. My skills end at sockets.

DoS can be performed in hundreds of ways, but I'd only reserve it for just causes.

sorry for idiot post BUT, when i try to open .txt document in firefox all it does is show the code, doesn't load page.

If you open a text file in Firefox, it will display it in plain text. This is still loading though, if you want to call it that.

are there any other recommended formats to save in?

What are you trying to save?

09-13-2007, 08:20 PM
eh, nvm about the saving thing, I just suppose my main question is if just having the code in the browser the same as having those little squares.

those little squares.

That makes even less sense; especially in my current state.

Are you talking about that code I posted above where I wrote "My alternative method (for *nix)"? If so, that can only be run on UNIX-like systems (such as Linux) -- it's a shell script. It would normally be saved as example.sh (though that doesn't really matter), then I would type in ./example.sh to run it.

On Windows, it's useless.

If you view a code in text file in your browser, or if you view code in code blocks on a forum, you're not running anything.

those little squares=iframe in halla's tut, but it doesn't matter now figured out.
