Lets face it... It happens....

You piss off the wrong guy, and you get threatened with that classic staple attack of all "hackers"... the DDoS.

Now you may be asking yourself, what exactly IS a DDoS attack? "DDoSing" refers to illegal Distributed Denial of Service attacks. In more simplistic terms, they are threatening to knock your internet out.

Now, how do they do this...?



Well a DDoS attack requires your Internet Protocol address and your port (Although some people can get away with using generic ports, it all depends on the situation)

Basically a DDoS attack, or the more generic type used, attempts to stress your internet to its breaking point. The method of doing this is different depending on the attack used.

The more common attack types include, but are not limited to:

UDP(Also known as HTTP-GET Attacks) - Is when the attacker request large files or responses from the target, eventually leading it to deny service to users.

SSYN- When the attacker sends data to the target server, then the server responds to the attacker, but the attacker does not respond to the server, leaving the connection to the server half open, which uses more system resources. The attack repeats this causing the server to deny service to users.

RUDY(R-U-Dead-Yet?) - is like SSYN attack but slower. It is more involved with the HTTP-POST attack. The attacker sends a HTTP-POST(This can be like server login, Feedback forms, and host Emails) request to the server. Normally it takes like 1 or 2 packets to complete this but with RUDY, it mimics the connection of a user with slow internet(This can easily bypass most DDoS Protection), sending various packets to the server over random time intervals. This uses system resources causing the server to deny service to users.

ARME(Apache Remote Memory Exhaustion) - It Basically exhausts the memory of servers denying server to users.

Now lets get down to the most important question of all, CAN they knock my server/internet off. In a short answer, yes; they very much so can.

Now how do you protect yourself?



Well lets go ahead and clear something up, those little "no-ip" servers, do not work at all. It is very easy to resolve an IP with those servers.

When a server advertises "DDoS Protection" you had better look into it very well. A "modified" IP still works in and of the same way as any other IP and doesn't do you any good.

What does do you good is making sure that the host can stop incoming "packet spams" from an IP. Basically they could "sense" when someone is sending a large (too large to be anything other than a DDoS attack) amount of packets to the specified IP address.

If you are more concerned with home connections being knocked off, just keep your IP address a secret, and stay away from programs that may allow public packets containing it to be sent to other users of said program. (Skype was notorious for this, yet most Skype resolvers are patched as Skype has changed some internal workings to address this security issue)

Basically, don't do anything blatantly dumb.

Help! I've been threatened!



Okay, so let's go ahead and clear this up.

More than likely the little imbecile that threatened you is nothing more than some kid that bought a membership on a premium booter. What does this mean? The "hacker" is using someone else's servers to launch a dedicated attack against you.

Basically, since most premium booters are overpriced, he may be able to knock you off at like five minutes at a time. Maybe more if he spent enough.

IF this happens to you, you're a weeee bit out of luck. The IP that will be flooding you with packets will more than likely be that of the booter service. However you can still blacklist this IP from sending you data, although I won't get into how to do that for the sake of simplicity.

If it's a long attack, simply unplug all of your internet related equipment. (Modems, routers, etc) Hopefully this will stop the attack. It works for most attacks. (This is IF you are using a home setup)

In conclusion...



If someone threatens to DDoS you, don't worry! More than likely you'll be fine! That is unless it's a serious DDoS'er who owns a slave net of zombie PC's ready to attack you on a whim! In that case pack your bags and pull a Snowden!

It should be noted that DDoS =/= hacking
People who DDoS who actually know what they're doing will actually be effective and take down whoever they want, such as the people represented in the logo you put in your post. But they do it for protest purposes, and in such cases they also know how to hack.
Chances are though, some kid that claims they'll DDoS you won't even know what a botnet means so don't even bother worrying. :D

This has happened to me before. Luckily the "hacker" did not know how to DDoS in the first place.. :P

o_o love that ending xD.
