Hello!

We wanted to check out how would our website show in a simulated DDoS attack.

I think this is one of the best tests one can do.

Does anyone have experience with this ? Did you do it yourself ?

I only am wondering how a DDoS script works? and how is it different from a real DDoS attack? :)

I am sure we will get a word from @VirtuBox on that.
In my honest opinion, I believe it will only show the consequences you can have when getting DDoS attack.
DDoS attacks can get nasty.I had experience with a colleague who was under DDoS attack by a rival crew, just out of envy and jealousy.
Thats why I asked how can one simulate it.

It's really going to depend on what kind of attack you want to simulate.

If you simply want to see how the website will perform with lots of traffic, something like Apache Bench will work. You also have to be careful simulating real DDOS attacks as if you have automatic protection this will likely get triggered to filter it. So many different ways to simulate it for sure.

Yes.
Those were my intentions.Just to see how will website react if it gets traffic, let say, 100%-500% more than usual.
I will use the tool you provided for me.
Automatic protection should be disabled ? Well, that is something I did not know about.
Many members suggested one of the ways so I will try them all.

You sure know that DDoS stands for a distributed DoS attack, don't you? It means that if you want to simulate it, you'll actually have to launch it from multiple locations, which is illegal even if you target your own server, simply due to the fact that it can damage your provider's network and require additional costs to mitigate against.

However, you still can stress-test your own server using a number of freely available DoS tools such as this one https://sourceforge.net/projects/loic/

I think using the term illegal is a stretch. You can initiate a DDoS and not cross the bounds into 'illegal' depending upon how it's done and who all is involved and notified.

Launching a DDoS attack from a botnet is illegal in almost every country, and this is how most attacks are expedited IRL. Thus, you can safely regard DDoS attacks as an illegal activity in most countries.

I'm not saying that OP will be prosecuted, most likely his provider won't even pay attention to the attack, especially if it has decent DDoS protection in place. However, the only legal way to launch a DDoS attack is to get written permission from all the parties involved and send packets from servers that you legally have access to. I'm not even saying that widely used DDoS attack amplification techniques are illegal too.

I know we're just arguing semantics as I understand what you're getting at. Sure, using a botnet which is comprised of hacked/compromised equipment would indeed be illegal. However, if I want to use all the nodes in our Texas facility to DDoS everything in our Washington facility there's nothing illegal about that at all. We own everything from A-Z and pay for any transit. The large transit providers really don't care/monitor what type of traffic passes along them anyways so as long as you aren't exceeding that causing them issues then really no problem at all.

But yes, get permission from parties involved if you don't own everything and execute the simulation from something you own and/or have permission to borrow and it's not illegal ;).

Wow, this kind of talk got me scared :LOL:
I see @KnownHost-DanielP saying that it is not illegal and , you @Marcus_SM saying it is illegal.
I did not do it yet, I was just trying to find answers.
I think I will stay away from it until I get all the information about doing it and is it harmful.

A DDoS script will send a lot of packet to the targeted host until it go down.
It's not a false DDoS attack, and using it elsewhere than on your own server (dedicated server, not VPS) isn't legal.
A DDoS script will send a lot of packet to the targeted host until it go down.
It it can do that, it is becoming a real DDOS attack?
