So you have a router at home, or you are using your laptop in a cafe or an open space and you have an unsecure wifi network setup. You might think: what’s the big deal? How’s that going to help anyone? Well as Oscar González shows, you need to be careful when using WiFi. Your files could be exposed. (from his Techie of All sorts) blog. Even exposing a little information via wifi can potentially expose alot.
Now, you might think: fine, he can look up all that information about me, including personal information…big deal. Well, actually for someone malicious — unlike Oscar — it can be a big deal. Alot of institutions use that information to establish your identity. Someone can get that information and commit some nice identity theft (not to mention other theft as well).
Short of it is: follow Oscar’s advice and secure your connections as well as other information about yourself out there.
P.S. Even if you are not a techie, you should check out Oscar’s blog and in particular this post.
