The opening line to this article sets the right tone:

"Daniel Gruss didn't sleep much the night he hacked his own computer and exposed a flaw in most of the chips made in the past two decades by hardware giant Intel..."

It reads like a thriller doesn't it?

This is because until very recently such an attack was not believed possible. The Intel chip goes to the "kernel" of your computer and if that is hacked then that represents a tremendous breach of security not thought possible. 

Not only is this breach possible but the vulnerability has been around since 1995 it is thought.

This particular team of computer technicians have already alerted Intel under "responsible disclosure provisions" to this vulnerability and a patch has been released. 

My only observation is this: if they can hack the chip itself, how much protection does a patch afford? Maybe they should be working on a complete fundamental re-design.
