Microprocessors: The Weakest Security Link

March 10, 2008
Although there seem to be limitless ways to attack computers, a vulnerability you might not have ever seen coming takes place in the microprocessors. As chips have become more powerful than , it is now possible for a person in a  chip fab or another in the supply chain to plant counterfeit chips in place of real ones.

The reason to switch out a chip has to do with taking control of a processor at a later date for a variety of nefarious purposes.

The complexity of today's chips is an issue as it has become impossible to check them for all potential responses before they are shipped.

U.S. security agencies are very concerned but many wonder why anyone would bother to target chips when so many easier ways seem to exists to hack into today's computer systems.
