Viewpoint: How hackers could decapitate the internet
A recent threat, purportedly from the hacker group Anonymous, stated boldly that its members would stop the internet on 31 March![]()
Those issuing the threat even stated how they would do it. They claimed they could disable the Domain Name Service (known by engineers as the DNS) and that would stop the internet.
The theory behind the proposed attack is based on the fact that the Domain Name Service is a tree structure: it starts with 13 servers at the top level and each of those talks to the next level down, which then pass it on to a further level down, and so on.
When the threat was made, it did cause some concern as the would-be hackers correctly identified the locations of the top level systems.

But there is a potential problem if hackers subvert the way the DNS has been set up to make it part of the attack.
This could be done by a process dubbed "amplification" which exploits two facts:
* A DNS query returns far more information than was in the request itself.
* It is relatively easy to falsify the address from which a query was sent.
To carry out the assault the hacker would first identify a target system and then create an army of bots spoofing its IP address.
This botnet would then send a large number of requests to the DNS which would reply, resulting in a much larger amount of data being fired at the target, causing it to be swamped.
Create several such botnets and select several targets and you can cause the DNS to flood the very network it is supposed to be serving.

but that's another conspiracy theory that's too crazy to believe.
