TippingPoint, a network-based intrusion prevention system company, has announced its plans for the Pwn2Own 2009 event - for the third year running. The event will be held at the CanSecWest Security Conference March 16th - 20th in Vancouver, BC. This years contest will target two sets of technologies: web browsers and mobile devices. As usual, the ZDI will purchase all winning vulnerabilities that are submitted against these targets, hand them over to the affected vendors, and coordinate public disclosure. The Zero Day Initiative will put up $5,000 per browser bug, and $10,000 per mobile bug.
