Australian Police Start War Driving [Broadband Reports]
If you live in the Australian state of Queensland, using an unsecured wi-fi router for your home network can be asking for a visit from the police. Like everywhere in the world, officials are concerned that criminals within range of an unsecured router can intercept network traffic between the router and other computers connected to that router. That network traffic could include personal and financial information, allowing criminals to misuse that information.
So, the police have decided to begin patrols to protect unwary citizens from their own unprotected wi-fi routers. According to Broadband Reports and the Sydney Morning Herald, Queensland police are driving the streets searching out unsecured routers and informing the owners of those routers about the dangers of leaving their router unsecured and providing them information about how to secure it. Queensland Detective Superintendent Brian Hay had this to say about the police resources dedicated to tracking down unsecured routers, "If we save mum, grandma and grandpa from losing their life savings, having their identity stolen or losing their kids' inheritance ... you ask them if they think it's a good use of police time and resources."
If you're running a wi-fi router without security encryption (or the outdated and easy to crack WEP encryption scheme), it's fairly easy to protect yourself from criminals that would steal your bandwidth, your identity and your money. This article from Microsoft details how to set up WPA and WPA2 encryption on your router.
