One out of every 50 packets on the internet is malicious junk intended simply to clog the tubes, according to a high level traffic analysis by Arbor Networks.
Distributed Denial of Service attacks or DDoSes aim to bring a site down by bombarding it with fake requests for a web page or image. It's like having 1,000 people continually crank calling a company -- the real customers can't get through.

How CloudNine Wound Up in Hell |
|
|
|
LONDON -- Fears are growing once more that companies operating on the Internet may not be equipped to ward off electronic sabotage after hackers forced a small British firm out of business.
CloudNine Communications, one of Britain's oldest ISPs, shut down last week with the loss of eight jobs in what computer experts believe is the first instance of a company being hacked out of existence.

If you want to bring down a country's information infrastructure and you don't want anyone to know who did it, the weapon of choice is a distributed denial of service attack. Using rented botnets, you can launch hundreds of thousands - even millions - of infobombs at a target, all while maintaining total deniability. In this hypothetical scenario, a single attack launched by China against the US lasts only a few hours, but a full-scale assault lasting days or weeks could bring an entire modern information economy to its knees.

The former director of the University of Tartu Institute of Experimental Physics and Technology d been the Estonian defense minister for only four weeks. He hadn't even changed the art on the walls.

Firms hit rivals with web attacks |
|

Technology Correspondent, BBC News website
Legitimate businesses are turning to cyber criminals to help them cripple rival websites, say security experts.
The rise in industrial sabotage comes as some suggest cyber criminals are turning away from using web-based attack tools in extortion rackets.
Experts suspect this is because of the risks involved in mounting such an attack on a web shop or retailer.
Instead the tools, usually hijacked home computers, are being used to pump out junk e-mail.

NIPC warns of possible DDoS attacks |
|
|
|
|
By Sam Costello
(IDG) -- The National Infrastructure Protection Center, the FBI's cybersecurity agency, issued an advisory Tuesday warning against the possibility of increased distributed denial-of-service attacks coming as a result of the last week's terrorist attacks against targets in New York and near Washington, D.C.
Denial-of-service attacks are attacks in which target computers are flooded with so many requests for information that they are overloaded and are unable to respond to legitimate requests for service. A distributed denial-of-service attack is one in which multiple computers worldwide are taken over and used to floor target systems from multiple locations. Such an attack knocked major Web sites such as Yahoo.com and Amazon.com offline for as long as a week in February 2000.
