A turf war has erupted on the internet between competing hackers trying to hijack computers running Microsoft's Windows 2000 operating system to turn them into "zombie PCs".
Variants of a "worm" that installs itself on computers connected to the internet so they can be accessed by hackers to send spam or disrupt networks hit several high-profile US companies early on Wednesday morning.
US broadcasting networks ABC and CNN were affected as well as the New York Times and Californian bulldozer manufacturer Caterpillar.
This side of the Atlantic, printing of Tuesday's edition of the Financial Times was also affected as systems went haywire.
Patrick Runald, senior anti-virus consultant at Finnish software security specialist F-Secure said the worms, also known as bots, are part of a new and growing trend among hackers to create zombie PCs. These infected computers can be controlled by hackers, and their computing power sold to the highest bidder for illicit purposes such as sending spam or directing network attacks.
"Over the last 18 months or so the virus writing world has changed. In the past, people just wanted to disrupt a lot of machines because it was fun. Now it is about making money, where people try and infect a lot of machines and make them into zombies," he said.
