Despite the latest patch for the security and the continued commitment of a company like Apple to try to make the native browser software for Mac OS X more robust , Safari could not resist the attack prepared for Pwn2Own 2011. French security firm VUPEN was first to attack the browser, and five seconds after the browser visited its specially-crafted malicious web page they were able to gain the access of machine. The compromised machine ran the latest version of Mac OS X (with all security updates installed correctly) to 64 bits.
iPhone hacker Charlie Miller demonstrated his way to attack on the iPhone browser mobile Safari, with the automatic deletion / access of the iPhone address book. The attack simply required that target the iPhone surfs to a rigged Web site. On first attempt at the drive-by exploit, the iPhone browser crashed but once it was launched, Miller was able to hijack the entire address book.
