Skyuser have reported that many of the free routers given out my Sky to their broadband cusomers may have a security vulnerability.

The threat is fairly remote as a potential attacker would need an advanced knowledge on Linux to be able to decipher the username and password.
The attack would involve using the default WPA passphrase printed on the router and the default SSID to connect via the wireless connection.

Sky have also  asked customers with with Netgear DG834GT routers to change their SSID and passphrase values security settings from the default values to overcome this problem. Customers should never really leave any security settings at their default values and choose custom a SSID with a passphrase with letters and numbers both in upper and lower case.
