“Open networks okay for sniffing”, says Illinois judge 43 by Nathan Snyder on September 10, 2012 9:54 am 4 So here’s the scenario: You have your own home network. It’s never been compromised as far as you know and it’s basically for sharing connections with tablets and smart-phones. Your WiFi hub is dutifully spitting out and receiving packets. One day, you get a notice from the MPAA saying you have a DMCA violation. They note they found it through your open WiFi network. Illegal? Not according to one federal judge in Illinois.
