Add Apple’s iOS and Research In Motion’s BlackBerry OS to the list of victims at this year’s Pwn2Own challenge. Conference veteran Charlie Miller, along with Dion Blazakis, deployed an exploit to iOS 4.2.1 through a vulnerability in Safari. By navigating to a custom-made webpage, the duo were able to execute remote code and gain access to the iOS address book. Vincenzo Iozzo, Willem Pinckaers, and Ralf Philipp Weinmann also utilized a WebKit-based vulnerability to take down a BlackBerry Torch running BlackBerry OS 188.8.131.52. The three researchers noted that the exploit used on the BlackBerry’s mobile OS was difficult to craft due to the lack of documentation, software tools, and resources available. They also noted that most of the operating systems security was achieved via obscurity, and stated that the company was “way behind the iPhone at the moment, from a security perspective.” No conference participants have yet to challenge Google’s Android or Microsoft’s Windows Phone 7 operating systems.
