DDoS
A denial of service (DoS) attack aims to render a web resource unavailable to its everyday users. It works by flooding a web server with more requests to serve a webpage than it can handle - meaning that during the attack period the hosted site will be dramatically slower to load or may not load at all. Another type of DoS attack - known as an 'email bomb' - targets an organisation's servers by sending more email than the systems can handle.

A distributed denial of service attack (DDoS) means multiple compromised PCs are used to overwhelm a website's bandwidth or resources. The machines used in such attacks are collectively known as a botnet or zombie network and will have previously been infected with malware - meaning they can be remote-controlled by the attacker.
The cyber criminal fraternity uses denial of service attacks as a weapon to blackmail ecommerce businesses, which rely on their websites being accessible in order to make money. Online gambling sites are popular targets - due to the nature of their business and the lure of ready money. But attacks are not always financially motivated - perpetrators can simply be seeking to cause disruption or make a name for themselves.
