Poor Wi-Fi security — my visit to the dentist


Yesterday, while waiting for a dentist, I took out my phone, turned on the Wi-Fi and poked around. What I found was depressing.

First, let me not gloss over the initial step, turning on the Wi-Fi. Good Defensive Computing demands that Wi-Fi be off when not in use. If there was anything I learned last summer attending the BSides and DEF CON conferences, it was to turn off Wi-Fi when your not using it. Trust me on this.

The phone saw two networks, one private and one for guests. The guest network was password protected, the only mistake not made by whoever set things up. As for the mistakes they did make:

1. WPS was enabled on each wireless network.
