Stuxnet worm reminds us of the need to keep work computers quarantined from home computers

Ellen Nakashima has a major article on the Stuxnet worm in the Washington Post om Saturday, Oct. 2, especially about the danger to U.S. power plants and other infrastructure. The link is here.

Apparently the worm can live on home computers with windows systems, probably without symptoms (rather like hidden "bedbugs"), but it could make home computers into “typhoid mary’s”. If some one uses a flash drive at home and then at work on certain machines in a power plant, the possibility of infection could exist, even though the power plant should not normally be accessible through the Internet. Government agencies and companies will have to be even stricter about keeping work and personal computers separate than in the past.

Because so many people use home routers and may bring wireless laptops home from work, there might also exist other ways of “cross contamination”. This is sounding like health department regulations for commercial kitchens.

I expect that Webroot and McAfee will be publishing blog articles about Stuxnet soon, as will companies in the process control software business.
