My girlfriend thinks she may be a victim of identity theft. She has dial-up at home, so she decided to use someone else's wireless. This morning she found out her password to her school account and aim were changed. She also bought some things over the internet, so she thinks this guy may have her credit card numbers. My guess is that whoever's network this is is the guy who stole her shit. My question is, would it be overly difficult to connect to his network, sniff it, and see if I can recover it using Etehreal or something like that? Are Aim passwords encrypted when sent over the network?
