Attacks begin on net address flaw

Attack code that exploits flaws in the net's addressing system are starting to circulate online, say security experts.

The code could be a boon to phishing gangs who redirect web users to fake bank sites and steal login details.

In light of the news net firms are being urged to apply a fix for the loop-hole before attacks by hi-tech criminals become widespread.

Net security groups say there is anecdotal evidence that small scale attacks are already happening.
