Please dont take this as gospel from me but read and digest it for what its worth. we all live in hope. Re: Christopher Tarnovsky aka Talking about Hacking NAG3 // 2010-02-04

WASHINGTON, D.C. -- Black Hat DC Conference 2010 -- The ultra-secure technology used to protect some of the world's most commonly used microchips might not be so secure, a researcher said here today.
Christopher Tarnovsky, a researcher at Flylogic Engineering who has made a business of hacking "unhackable" chip technology and other hardware, was at it again today with the revelation of vulnerabilities in the Infineon SLE 66 CL PE chip, which is widely used in computers, gaming systems, identity cards, and other electronics.
Tarnovsky offered a step-by-step explanation of his successful efforts to crack the chip's defenses using electron microscopy. During the course of about nine months, Tarnovsky said he was able to bypass the chip's myriad defenses and tap into its stored information without detection or chip failure.
"I'm not saying it was easy, but this technology is not as secure as some vendors would like you to think," Tarnovsky said.
Using a painstaking process of analyzing the chip, Tarnovsky was able to identify the core and create a "bridge map" that enabled the bypass of its complex web of defenses, which is set up to disable the chip if tampering occurs. After creating the map, he used ultra-small needles to tap into the data bus -- without disturbing the protective mesh -- and essentially "read" all of the chip's stored data, including encryption keys and unique manufacturing information.
Using this data, criminals could potentially re-create the chip in order to develop counterfeit systems or subvert widely used systems, Tarnovsky said. Such exploits could allow criminals to break through the defenses of pay TV services, medical ID systems, or even Microsoft's much-vaunted Xbox license chip, he said.
Tarnovsky said he has informed Infineon of the flaws he has discovered, but so far the company has not responded. "Their initial reaction was to tell me that what I'd done was impossible," he said. "Then when I sent them some video and the code that I just showed [to the Black Hat audience], they went quiet. I have not heard back from anybody."
In addition to Infineon, Tarnovsky said he informed officials at the Trusted Platform Module (TPM) standards organization, which sets security guidelines for the widely used PC chip standard. But he has not heard back from them, either.
Tarnovsksy said he believes similar exploits would be possible with other chips as well as Infineon's, though he has not attempted them yet. The exploits would not be easy to reproduce -- Tarnovsky said he went through many chips and many needles, and electron microscope time costs $350 per hour. "But the reason it took so long was not so much what the vendors have done, but me learning how to do it," he said. "Once you know what to do, it's not incredibly hard."
Personally I think Chris was wrong to give them any clues or help of what he did. :congrats:
