LAS VEGAS -- The Apple Store at the Fashion Show Mall has a solid crowd for a Monday afternoon and it's easy to pinpoint the favorite.
A dozen iPhone stations collect at the front of the store, and they are rarely lonely. A stylish 20-something couple laughs as the man snaps a picture of the woman and shows her the screen. A brown-haired woman wearing a UNLV t-shirt moves her fingers over the display and smiles as the device responds. The ready touches and kid-in-the-candy-store smiles are likely just the reaction that Apple CEO Steve Jobs hoped to elicit with the device.
However, the iPhone has gotten a lot rougher treatment from the hackers and security researchers that will converge on Las Vegas for the Black Hat Security Briefings and the DEFCON hacking conference this week.
A month after its release, the iPhone has been poked, prodded, torn apart and made to reveal a number of its secrets. Hackers have already learned how to build and install programs on the device, a considerable feat as Apple has not published any application interfaces or development kits for the iPhone. And bug hunters have had wins of their own: On Thursday, Charles Miller, a security researchers at Independent Security Evaluators, will reveal the details of a significant flaw found in the device's stripped-down Web browser -- a flaw that Apple patched on Tuesday.
For Miller, there is no secret about the reason for all the attention. Since its launch a month ago, the iPhone and its slick interface have garnered rave reviews from tech-savvy users. Hacker and security researchers are no exception: Miller carries his own iPhone and quickly pulls it out upon request over breakfast Tuesday.
"The iPhone is cool," he said.
Yet, the popularity of the sleek phone has also lured hackers to pull apart the device and flout Apple's restrictions on developing software for the device. And, just as they took to Macs and MacBooks, security researchers have focused on finding flaws in the iPhone's operating system and software. It's the dark lining to Apple's silver cloud.
"The bottom line is that people will find ways of accessing the device," said Mikko Hyppönen, chief research officer for antivirus firm F-Secure and an expert on mobile-device security. "I'm guessing there will be more activity for the next six months on the iPhone then there will be on the Macs or OS X."
Already, the first month's flurry of hacking rivals the attacks of late last year that focused on cracking the security surrounding the next-generation Blu-Ray and HD DVD video formats. The poking and prodding have also born fruit: Security researchers have already identified severe design weaknesses in the iPhone. At the top of the list, the device's operating system runs every application with administrator privileges, according to Miller and his cohorts at Independent Security Evaluators, turning a simple breach of any application into a breach of the system. In addition, both the iPhone's stack and heap are executable and the layout of programs in memory are not randomized -- two factors that make exploitation of any vulnerabilities much easier, he said.
"I think people are letting Apple off easy," Miller said. "You need to design the iPhone so that even if there is a problem in Safari, people don't completely take over your phone."
