For day two of Black Hat, we sat in on on [Joe Grand], [Jacob Appelbaum], and [Chris Tarnovsky]’s study of the electronic parking meter industry. They decided to study parking meters because they are available everywhere, but rarely considered from a security perspective.
Peripheral manufacturer Datel has been hard at work attempting to crack the PSP 3000 since its release. They’ve developed the Lite Blue Tool battery to force the PSP into service mode so hackers can run any arbitrary code they want. According to MaxConsole, Datel performed a silicon level investigation of the PSP’s chips to determine how to break into service mode. This means they decapsulated the the chips and reverse engineered any cryptographic protections. We’d love to hear exactly what chips were being used since some are fundamentally flawed.
Silicon hacking has always been a favorite topic of ours and we suggest you check out [Chris Tarnovsky]’s decapsulation technique to learn more about it.
