A Russian firm used Nvidia's graphic cards, capable of doing the brute for calculations required for just this task, was able to crack through Wi-Fi's WPA/WPA2 encryptions.
A while back, there were stories of how cartels or criminal organizations can hook up a bunch of PS3 together to break bank securities or other network securities. I haven't heard much about it since but I'm sure like everyone else, we have taken Wi-Fi security for granted and now, with parallel processing much easier, Wi-Fi security is not as secure as we think.
Now, this is not to say that we no longer will be able to use our wireless routers at home. I doubt there are roving gangs of high-tech hackers targeting individuals. According to SC Magazine , Global Secure Systems believes companies should elevate their Wi-Fi security to using VPN.
Nevertheless, the fact that someone can use a standard PC with graphic cards doing this is somewhat amazing, don't you think? I don't know how much the rest of us average mobile warriors have to worry about this. Most of us with our home networks are not likely to be targets of corporate espionage. And if you think you might be, I expect you to be using VPN. If not, best to do so.
I think it won't be long before even consumers will be offered more higher grade security solutions. Is that necessary? Would you consider upgrading?
Note: Makes you wonder how secure WiMax and 3G is.
