Virtual nuclear bomb called biggest cyber attack ever

The internet was hit with the virtual equivalent of a nuclear bomb, and it's slowing down connection speeds all across the globe. Some are calling this the biggest cyber attack ever made public. But who's behind it? China? North Korea?

Would you believe it's the same people who allegedly fill up your spam box with weight loss ads, and offers from Nigerian princes?

On one side is a company based in Europe called Spamhaus, an internet spam watch dog. The company creates spam data filters so that 1.4 billion users, businesses and individuals alike, don't have their inboxes filled with unwanted ads.

On the other side is  Netherlands-based Cyberbunker, a web hosting service black listed by a Spamhaus because Spamhaus said too many of the companies Cyberbunker hosts send too much spam.

Two companies are having a fight, and as long as it stays there, nobody cares.

But Cyberbunker struck back electronically, pouring data in on Spamhaus, trying to cripple its computers, or so it appears. Spamhaus has so many clients and connected people that there is a fear that Cyberbunk's attack is slowing down business in many places.
