PC retailer Computer Exchange is the latest company to fall prey to hackers who are targeting corporate websites.

The hackers, who call themselves Adhinsh, left a message attacking Computer Exchange users. A spokeswoman for Computer Exchange said: “It is distressing that this sort of thing is becoming increasingly common on the net.”

She added: “Our home page was defaced but they couldn’t touch our site. We are a bit bemused by the motivation for the attack.”

The incident follows a number of high profile attacks on websites using Microsoft Internet Information Servers (MIIS). On Wednesday, the UK websites for car manufacturers Mitsubishi and Fiat were defaced by hackers calling themselves Prime Suspectz.

Prime Suspectz was also responsible for an attack on Microsoft’s New Zealand website on Tuesday.

Paola Bassanese, an e-business analyst for IT consultant Ovum said: “Companies need to be proactive in applying security patches from software vendors to secure their servers. If this is not done regularly this vulnerability can be exploited by others.”

She added: “It is not easy to hack into these systems but there are people who devote their lives to this sort of thing.”
