Timely reality check...
Grunwald says he's succeeded in sabotaging two passport readers made by different vendors by cloning a passport chip, then modifying the JPEG2000 image file containing the passport photo. Reading the modified image crashed the readers, which suggests they could be vulnerable to a code-injection exploit that might, for example, reprogram a reader to approve expired or forged passports.
"If you're able to crash something you are most likely able to exploit it," says Grunwald, who's scheduled to discuss the vulnerabilities this weekend at the annual DefCon hacker conference in Las Vegas.
