Greetings from CanSecWest ! Ok, I am not there but I have some friends that are actually there :). The interesting news that they sent from there is regarding a 0-day exploit for the Apple's Safari web browser. According one post of the hacking contest, one fully patched OSX machine was owned due a exploitable flaw on Safari, triggered when visiting a malicious website. The bad thing is that there not a single word on the latest Apple Patch Release of any Safari related flaw. So, if you use Safari, stay tuned for more informations!
