There are a couple of ‘security’ conferences taking place right now where professional hackers from around the world are showcasing their considerable talents to win cash prices and kudos.
A couple of them managed to hack past IE 8 and get into Windows 7, maliciously, with ease. But, other hackers also managed to skirt past security on FireFox running on Windows 7. So that is not good. As far as we know none of these ‘exploits’ are being exploited right now to hack into Windows 7 systems. All it means is that there are people out there who know how to do it, IF they wanted to.
No updates from Microsoft or Mozilla as yet.
All the best.
P.S. No Windows 7 updates today, i.e., March 26, 2010
