of encryption we re safe. tell us about the vulnerability that was recently uncovered. a lot of people will see something called wpa2. that s the encryption standard out for 12 or 13 years. what the researchers found. i was glad they did it this way. what they found is that if they could trick the router into reusing a set of keys, part of it is called the key recovery, it is regenerating the same keys it fools you into thinking you haven t used this particular encryption key before. if you have that s how they were able to break it. you think your blinds are down and your virtual blinds are up. we see the data because you think it s encrypted. jon: these are public networks if i go into a coffee shop that provides free wifi, am i vulnerable? if you re an free wifi and no protection you re vulnerable.
i m here in the d.c. bureau now. congress is behind us, all the wifi access points out there supposed to be encrypted. if i could get close enough to the access point and i can see the data going across it. public wifi is its own issue. the ones that have encrypted the networks and you have to have a password to join. this exposes that. the equivalent of being on public wifi and having everybody see what you are doing. jon: how do you know whether your information is vulnerable or not? you will see a series of updates coming out from a lot of people to say update firmware. they will fix the problem and standard. operate under the assumption yr data is out there. there is a step you can take. a lot of people is called a virtual private network. you can go online and find a reputable one. there is a place in there. look at those things. it is $40 a year but cover your
