I thought DDos was the same as doxxing someone, turns out I’m just stupid.

I’m wanting to go the store known as Amazon.com. There is only one way to get there.

Some other guy decided that he is gonna send a billion people to the store. The store can’t handle this many people!

Now I’m stuck trying to get to the store cause there is too much traffic.

This is a DDoS. This guy has denied me service of the store Amazon

Yes, those are completely different.

A distributed denial of service involves causing many computers to send messages as fast as they can to one computer, often the computer hosting an adversary’s web page. All these requests overload the target computer, the “website is down”. This is annoying to the website owner.

Doxxing someone is a personal attack on a human, revealing their actual home or phone or job or …, in hopes that the evildoers on the Internet will disrupt the person’s life. This is sometimes a crime, depending on where you live, but it’s always a dastardly thing to do for which the perpetrator deserves a harsh punishment.

Essentially someone can hijack a bunch of computers at once to go onto the same website at once so it crashes and doesn’t load for other people. that’s distributed denial of service.

To dox is to find someone’s personal info and post it.

It’s a virtual flashmob, where you’ve blackmailed (hacked) every person (computer) in the mob to do your bidding and rush to a destination (e.g. a store) and ask for a service. Because the store cannot serve so many customers, it results in a complete breakdown, or very slow service for actual customers.

Denial of Service is basically preventing the target online server from responding to legitimate requests (aka pings), usually by overloading it with a huge number of bogus requests. This is slightly difficult to really scale (you need to be able to send enough pings) and easy to block (the server just blocks/ignores any IP sending more than a certain number of requests per second).

Enter Distributed Denial-of-Service where the first step is to spread some sort of malware which would make target infected computers send pings to target servers for you. This results in what’s called a botnet (a network of bot computers doing your bidding). The malware could do other things too (e.g. provide you with additional computational powers to brute-force other hacks), but right now we just want pings. Then you get this botnet to attack your target server with numerous pings. It’s like a million people repeatedly asking you for your name while you’re trying to get some work done. Now even DDoS attacks can be blocked, but it’s difficult, because you need to block a lot IPs instead of just one. This has become such a problem that most companies now use dedicated services like cloudflare to protect themselves from such attacks.

I just got fired from my job at Dominos, and I want to get revenge. On a night that I know they’re going to be extremely busy, I keep calling them just to ask what time they close. If I’m able to do that fast enough I can overwhelm their phone lines, and people who legitimately want to order a pizza either won’t be able to get through, or will have a very hard time getting through. This is a denial of service attack.

Dominos figures out what I’m doing and blocks my number. So the next time I want to mess with them, I get all my friends to call Dominos and ask what time they close. I have now distributed my denial of service attack.

It’s like the [Berner’s Street Hoax](https://en.wikipedia.org/wiki/Berners_Street_hoax) except with data packets over the internet instead of pianos and Bishops in the street.

Ddos attacks are the PC equivalent of sending someone a package from Amazon or whatever.

Pretend I buy you an empty box and mail it to you. Haha it’s whatever though just a box.

Now imagine if everyone in your school/work does it on the same day.

You open the door and packages all over the front porch.

Now imagine if the country of China all did that to you and all the packages are delivered at once.

Now you can’t get out of your house as it’s surrounded.

It’s sorta like that. In layman’s terms it’s artificially overloading a server.
