At a recent ISSA meeting, a team of FBI agents demonstated how to crack the 128 bit WEP encryption used by wireless routers. They used freely available tools and accomplished their task in about 3 minutes. Over at Tom’s networking, they have an article that covers how the FBI did this in great detail.

It time to run the firewalls on the computers behind the router. I want a tool that can tell me if someone is trying to hack into my network.
