From Threat Level:Electrical blackouts impacting millions of people in Brazil in 2005 and 2007 were caused by hackers targeting control systems, according to the CBS news magazine 60 Minutes.
In a show set to air Sunday night, CBS blames a two-day outage in Espirito Santo in 2007 on a hack attack. The blackout affected three million people. Another, smaller blackout north of Rio de Janeiro in January 2005 was also triggered by computer intruders, the network claims.
My Comment: I am sure there are now more safeguards to prevent such occurrences from happening, but it is an excellent example to use in revealing how easy it is to put down a power grid.
