Pwn2Own hacking competition at CanSecWest and already Apple, Microsoft, and Mozilla have been sent packing to their respective labs to work on security issues in their browsers. In a repeat performance, Charlie Miller pocketed a $5,000 cash prize and a fully-patched MacBook by splitting it wide, and gaining full control of the device after a user clicked on his malicious link. Another white-hatter by the name Nils (pictured) toppled Internet Explorer 8 running on a Windows 7 laptop -- again, the five grand and compromised VAIO P laptop are now his to keep as compensation for turning over the malicious code. So much for "protection that no other browser can match," eh Mr. Ballmer? Nils then demonstrated a second Safari exploit before hacking Firefox later in the afternoon netting him a cool $15k by the close of day one. Only Google's Chrome was left unscathed -- Opera isn't part of the contest. This year's contest will also offer a $10,000 prize for every vulnerability successfully exploited in Windows Mobile, Android, Symbian, and the iPhone and BlackBerry OSes. In other words: this contest that runs through Friday isn't over by any stretch.
