摘要

Las vegas ― Traversing the carpeted walkways of the Las Vegas Convention Center last week, Caleb Sima looked like many other programmers at Comdex: young, lean, laid-back and with a taste for earth tones. What was less apparent is that he also has a penchant for uncovering new security threats. "I dabble in cell phone security for fun," said the CTO and co-founder of Spi Dynamics, an Atlanta company that makes software for uncovering vulnerabili- ties in Web applications. Sima spoke on a panel about the growing handheld security threat, a hot topic at a conference where dozens of mobile network products were on display.
