Baby can hack you

By
Network World Fusion, 09/11/02

The wireless security zone at the NetWorld+Interop I-Labs features a wireless PC near a wireless access point that is sniffing traffic and displaying what it finds.

What it finds are a lot of passwords being used in the clear by attendees who are logging into the show network via wireless PCs. The equipment is set up as a very effective demonstration of the simple fact that security is a must for wireless networks.

The sniffing PC is picking off wireless traffic via a setup that includes an empty baby-formula can as an antenna. This has its humorous aspects, similar to the demo at an earlier trade show in which a vendor ran DSL over barbed wire just for the heck of it.

But the formula can is also practical. "It gives us a little more gain than the antenna in the wireless card," said one of the I-Lab volunteers.
