This week a program was released to allow brute force cracking of vulnerabilities in wifi protected networks. The program called reaver brute force cracks the encryption on almost all major routers (including Cisco/Linksys, Netgear, D-Link, Belkin, Buffalo, ZyXEL and Technicolor.)This program will brute force crack the push button connect encryption on newer routers allowing the device using reaver access to anything on the network.

This is a huge security flaw for small to medium size businesses that have all there computer's networked allowing the person cracking the network access to all the permissions of a network admin. That basically sums it up. Check out the article if you'd like, it goes into much more detail about the exact process and explains how to prevent your own network from being cracked.
