University of Illinois researchers altered a computer chip to grant attackers back-door access to the system – a complicated hack to pull off in the real world, but one which would be virtually undetectable.
To launch its attack, the team used a special programmable processor running the Linux operating system. The chip was programmed to inject malicious firmware into the chip's memory, which then allows an attacker to log into the machine as if he were a legitimate user. To reprogramme the chip, researchers needed to alter only a tiny fraction of the processor circuits. They changed 1,341 logic gates on a chip that has more than 1 million of these gates in total, said Samuel King, an assistant professor in the university's computer science department.

All I can say is that these Illinois researchers arn't helping us, they're proving something to hackers and a profitable route for companies.

King demonstrated the attack at the Usenix Workshop on Large-Scale Exploits and Emergent Threats, a conference for security researchers held in San Francisco.
