IOActive security researcher Dan Kaminsky offered his much-anticipated speech on the DNS vulnerability at the Black Hat conference on Wednesday. His message: Patching your systems is urgent because the risk of cache poisoning is great.

Kaminsky discovered the bug in early July. The attack code was released several weeks later by developers of the Metasploit hacking toolkit, headed by the infamous HD Moore.

AT&T's new technology chief says his goal can be summed up in five words: "More bandwidth in more places."

"You also have to be good at getting (consumers) on and off the network," says John Donovan, formerly with Internet security giant VeriSign. That's a tall order. About 1 billion devices connect daily to AT&T's networks: local, long-distance, broadband and wireless. The number is rising thanks to America's fascination with mobile -- smartphones, laptops and more.
