Seems that the the work laptop is the target for the corporate hacker these days. Yes you may wpa2 set up but is the security on the laptop as good as what the business uses, i doubt it.
I was reading an article on this and it stated this very fact that hackers can carry out their attacks by hijacking corporate laptops due to this very fact. Nothing stops them placing a trojan that hasn't been detected yet, and then when you connect to the proper network, the trojan transfers itself and launches its payload.
2 options were given in the article, one that companies stop handing out laptops and everyone has to use desktops at work from now on, or that workers will buy their own and carry on as usual. Guess which one i see happening.
