One issue may be that the usage share for IE10 is almost negligible currently because it hasn't landed on Windows 7 yet. (But it will soon, so... hmm.) Pwn2own bounty for breaking IE9 is only $75,000. Bug price list 1 year ago: http://www.forbes.com/sites/andygreenberg/2012/03/23/shopping-for-zero-days-an-price-list-for-hackers-secret-software-exploits/ http://www.forbes.com/sites/andygreenberg/2012/03/23/shoppin... It is indeed too bad that the Safari bounty is only $65,000. And IE9's bounty is only $75,000. So yeah, perhaps these bugs are being sold to governments instead.
