Security Chip Hacked

Found an interesting article about the TPM chip, made by Infineon Technologies. Christopher Tarnovsky , a former U.S. Army computer-security specialist, was able to hack this particular chip , which is suppose to be the industry's most secure. According to the article it took 6 months for Tarnovsky to figure it out. He first had to soak the chip in acid and then he applied rust remover. There were other things but I'll let you read the article. I guess I never thought that hacking would require acid or rust remover. When I think of hacking I picture someone using some type of computer equipment.
