This type of attack involves massive network layer DDoS attacks through to focused application layer (HTTP) floods. Typically, the perpetrators can simultaneously use from 2 to 5 attack vectors involving up to several tens of millions of requests per second, often accompanied by large SYN floods that can not only attack the victim but also any service provider implementing any sort of managed DDoS mitigation capability.

The CEO of Valtia Simo Rounela said that the central heating system and hot water system in both buildings had become a target of DDoS attacks. The incident is extremely worrying because in a location as cold as Finland. The attack started in late October and ended on 3rd November afternoon.

There are two general forms of DoS attacks: those that crash services and those that flood services. The most serious attacks are distributed.

Many attacks involve forging of IP sender addresses so that the location of the attacking machines cannot easily be identified and so that the attack cannot be easily defeated using ingress filtering.

Criminal perpetrators of DoS attacks often target sites or services hosted on high-profile web servers such as banks or credit card payment gateways. Revenge, blackmail and activism can motivate these attacks.

In computer network security, backscatter is a side-effect of a spoofed denial-of-service attack. In this kind of attack, the attacker take-off the source address in IP packets sent to the victim.

In general, the victim machine cannot distinguish between the spoofed packets and legitimate packets, so the victim responds to the spoofed packets as it normally would. These response packets are known as backscatter.
