iPhone gets "pwned" at hacker conference.

Two researchers participating in a hacking contest this week brought down the Apple iPhone, a difficult assignment considering the latest version of the popular mobile device contains new security measures designed to combat exploit attempts.

Participating in the Pwn2Own contest as part of the CanSecWest conference in Vancouver, Vincent Iozzo and Ralf-Phillipp Wienmann used a technique known as return-oriented programming to exploit the bug in the iPhone's Safari browser.

The vulnerability allows an attacker to execute remote code if a user is tricked into visiting a malicious website via the Safari browser. The payload, as the two men demonstrated, allowed them to steal messages contained in the phone's SMS database and send it back to a web server under their control.

To launch the exploit, the researchers had to find a way to evade code signing and data execution prevention safeguards present in v2.0 of the iPhone, meant to limit arbitrary code from running on the device.

"It is the first time that this technique has been publicly demonstrated on a real-world telephone," said a news release announcing the feat. "The demonstrated attack code steals the SMS database from the phone, albeit other attack payloads are easily possible."

For their achievement, the researchers won $15,000.

According to reports from the contest, Safari on the MacBook Pro also was successfully exploited at the hands of renowned Apple hacker Charlie Miller of Independent Security Evaluators.

Internet Explorer (IE) 8 and Firefox 3, both running on 64-bit Windows 7 machines, also fell. Google's Chrome browser, apparently thanks to its "sandbox" features, has so far survived another year of competition.

Researcher Peter Vreugdenhil was responsible for the IE hack, while a white-hat hacker known as "Nils", of security testing firm MWR InfoSecurity, accomplished the Firefox exploit.

All of the exploits took the winners just seconds to demonstrate, but months of research to devise.

TippingPoint's Zero Day Initiative, which offers the cash prizes, acquires the rights to the vulnerability discoveries and soon will send details to the affected vendors.
