Experts last week showed how to put together a wireless hacking kit for less than £1,200. Speaking at NetEvents, Jan Guldentops, director of Better Access Labs, demonstrated how a hacker could create the kit using "any old laptop, an antenna, GPS, power unit and software. And the entire thing fits in a briefcase."
Guldentops said the advent of a wireless standard meant it was easy for external hackers to access the wireless Lan. "I spent two weeks in Belgium just driving round looking for open wireless networks. I found 263 and was able to connect to 85 per cent of these immediately," he said.
Those with zero security included "banks, police offices, and Belgium's biggest brewery."
