Cyberwar erupts over WikiLeaks

A cyberwar is being waged over WikiLeaks. It began after MasterCard, PayPal and Visa refused to take payments for WikiLeaks, which runs on donations.

In retaliation, a hacker group calling itself "Anonymous", launched Operation Payback: targeting the credit card companies, with what are called "Denial of Service" attacks.

They managed to temporarily take down Visa and MasterCard's main websites.

But the companies say transactions were not affected.

Now, Twitter and Facebook have suspended the accounts of the "Anonymous" group.

Twitter was being seen as a rallying point for the so-called "hacktivists".

In an interview with Al Jazeera, Kevin Anderson, a technology journalist and a specialist in New Media, shares his views on the cat-and-mouse game being played out on the internet.
