A dangerous wireless security problem has been exposed

[Computernerd22]

A dangerous wireless security problem has been exposed in most laptops running a recent version of Windows at ShmooCon, the hacker conference held in Washington DC.

The laptop must be running Windows XP or 2000, have built-in wireless functionality and be unprotected by firewall software.

The flaw is based on how the operating system is configured to search for any available wireless connection when the laptop is started up. If no wireless link is found, Windows creates an ad-hoc "local link address", instead of a "private network".

The address becomes associated with the name of the last wireless network that provided the user with a real web address. Windows then causes the laptop to broadcast that network name to other computers in close range of the machine.

By creating a network connection on his laptop that matches the network name being broadcast by the target machine, the two laptops could communicate with each other on the same local link address. And the hacker effectively gets control of your laptop.

So XP SP2 is invulnerable in it's default config. Laptops without built in wireless is invulnerable - though I doubt that, if it has a wireless card in it, it's probably vulnerable pre XP SP2.

I need to research it further but right now it's probably a bit more FUD.....

Hey Guys,

I know virtually nothing about wireless (even my radio has a hand crank, and that is true! ) so this is a genuine question from a different angle:

The laptop must be running Windows XP or 2000, have built-in wireless functionality and be unprotected by firewall software.

Now that would sound like my idea of "wardriving kit", so, would wardrivers be vulnerable to this?

As I said I know very little about this area.

Nihil, I beleive that wardrivers are less like to have a problem with this since the idea is find the networks and not so much as to actually connect to them. Most of the tools I use make it clear what type of network is availible. ad hoc or managed, open or encrypted, but doesnt actually establish a connection. The people using the public hot spots are the ones that should be worried the most.

I think you will find you are correct with the, "FUD", statement.

Just working the way it should do. Have a read of this if you wish:http://it.slashdot.org/article.pl?sid=06/01/15/0815207

I would think that if you have ANY pc/laptop connected to the internet in any fashion without a firewall you will be vulnerable on several levels
