Hey, I got a DoS attack question. This in theory works, by sending a large ping to a website. The server takes the ping in small amounts, and then collects it all at once resulting in a crash. Here if the theory. "ping -165527 -s 1 target" and for example google "ping -165527 -s 1 www.google.com" would this work? Got it from a Dos Attack website.

pinging will not do shit. And also... google... is very hard to bring down.

I've tried to explain this to like, 20 different people (not on this site) that it doesn't really work. XD

also, typing "www." is un-needed, in almost everything...

the dos attack is a very very old exploit of windows 95 systems, it was once called "the ping of death" and and basically overloaded windows then
it epic failed. this bug was fixed quite quickly by microsoft after many complaints because people were not shutting down websites but just peoples desktop pc's; sending a large ping to a random IP. google are clever enough not to be running an old version of 95 (which was a buggy system in the first place) for their webservers. probally got some custom linux distro i bet. id say whoever told you that diddnt know what they were on about or had been led up the wrong tree themselves.

lockie shut the fuck up. now. please.

Windows 95 isn't the only thing a DoS attack can hit. A DoS, if you could be bothered to look up, is a 'Denial of Service' attack, meaning, if it causes the system to lockup or crash, or just generally become not available for use, it might have fallen victim to a DoS attack.

Say I have a bank of 300,000 computers. That's a fucking lot of machines. Every one of those machines is in Tokyo, Japan. The average bandwidth over there is pretty fucking high, around 60Mb a second.

So going with that idea, I hate acb.com. we've tried in the past to take it out, fuck it up, and rape it in the ass when everyone was looking. Sometimes we got somewhere, usually we didnt. Lets supposed that one night, I get horridly drunk and decide that once and for all, acb.com is going down.

How can I do it you ask? Well sure, I could spend some time picking the sourcecode to vBulletin apart and look for a vuln in it, and hack that..

But, remember, I was drunk... really fucking drunk....

What's an attack that takes no skill at all and does more short term damage than a gallon of tequila? DDoS. (Distributed Denial of Service).

So I'm pissed off, and I've got 300,000 computers hooked up to some of the fastest residential internet in the world. I essentially have a botnet under my control.

hooray me!!

I make every one of those computers flood acb.com with HTTP requests, at the same time, nonstop for days.

The server's going down, probably in 10 minutes. It will be down until someone starts redirecting my packets somewhere else... how they do it, is their problem; not mine.

So yeah, there's more to DoS than Win95 and 'the ping of death'.... fucking moron.

normally, but I forgot the exact date, think it was in 2002, two guys using a trojan virus to try and DDoS attack some large internet server were shut down by those people who look out for large threats on the web, some initials and junk, and they say that if they would have succeeded, they would have shut down most of the web. (I know this is really vague, I had a project on DoS attacks a few years ago, so I can't remember the details, or what exactly it was that they tried to shut down...)

You don't need to know how.

And not to come off as a smartass, tis not my intention; but you seem to have mixed up some terminology. Allow me to explain:

DOS is a Microsoft Operating System.
DoS is a Denial of Service.

There is a slight difference, depending on who you ask.

Essentially, what a DoS does is deny a service from a client, eg. A SYN flood could cause a DoS and thus disrupt someone's internet connection for a few minutes.

Typically, though, a traditional DoS is some sort of system attack (against the kernel or something) that completely denies all contact between the nodes (server->client, client->server, etc etc).

What most people are talking about when they address a DoS is actually DDoS or Distributed Denial of Service.

The methodology behind a DDoS is to get as many clients to try and connect to a server that it overloads and crashes/shuts down/etc.

Usually a pretty n00b thing to do, it can also be used as a diversion for masking a larger scale attack somewhere else.

An example might be to DDoS a companies SMTP server(s) and take them out while you're rooting the SSH. This attracts their attention over to the SMTP.... because all of a sudden all of the company email stopped. Meanwhile, you're sittin' pretty on a root ssh login.

I wont tell you how to do any of it, but thats a general overview of what it means and what its uses are.
