Network Admin Nightmare #5 - Unprotected Laptops

With so many staff working at home one or two days a week and everyone wanting connectivity from anywhere in the world, laptops have become very important tools.

Pretty much every organisation now has a VPN to give staff remote access across the Internet, yet a tiny minority understand how much at risk they are from laptops. If an attacker were able to gain control of a lost or stolen laptop, they would have access to all the information stored on it plus the opportunity to connect to the corporate network via the VPN.

From time to time we are asked to test the security of a laptop build - perhaps the organisation is intending to migrate to a new version of Windows or has simply designed a new “build” - in any event we are asked to test the security of their standard laptop configuration.

Our first check is to see whether a BIOS password has been set. This poses a small hurdle to the would-be attacker, one that is usually overcome fairly simply by a bit of jiggery-pokery on the motherboard or by removing the hard disk and putting it in a another system. A hard-disk password is a different problem, which often requires specialist assistance, and is therefore considerably more effective.

Unless that is, the hard disk password is the same as the BIOS password in which case the problem is solved. However we have yet to find a corporate laptop utilising either form of power-on password, probably because of the anticipated support costs of all those forgotten passwords!
