Computer experts and interested amateurs are joining forces to map out wireless networks around the world and find out how many are secure.
The results of the first mapping expedition reveals that, despite the publicity about the security problems of wireless networks, many companies and consumers are leaving networks open to attack.
The first survey revealed that 70% of the wireless networks found do not turn on the encryption system built-in to the products.
It also revealed that 27% have not even changed the default name of their wireless components making it very easy for people to surreptitiously sign in and use the network.
