jjp9999 writes: Based on claims that silicon chips could be infected, security researcher Sergei Skorobogatov claims he and his team developed chip scanning software to put this to the test. They got their hands on a US military chip "that is highly secure with sophisticated encryption standards," that also happens to be manufactured in China. What they found was the chip has a backdoor on it that can disable the chip or reopen it at will. "This particular chip is prevalent in many systems from weapons, nuclear power plants to public transport. In other words, this backdoor access could be turned into an advanced Stuxnet weapon to attack potentially millions of systems. The scale and range of possible attacks has huge implications for National Security and public infrastructure," Skorobogatov writes on his blog. Link to Original Source
