A few years back, after a major blackout hit the northeast, many people immediately assumed that it had something to do with a terrorist attack on the electricity system or perhaps a computer worm/cyber attack. It turned out to be neither, but it wasn't that surprising that people jumped to that conclusion. However, afterwards, people began discussing how likely it was that a cyberattack really could take out the power grid for a city, and some people felt that it was fairly unlikely to occur. The CIA, apparently, would disagree. Late Friday, a CIA official claimed that cyberattacks have been to blame
for certain blackouts over the past few years, and that the agency had debated whether or not to release that information publicly. Of course, without much in the way of detail, it's difficult to have any sense of what's actually happening here and how accurate the information really is. However, we will repeat what we said after that huge blackout: even if it was a cyberattack, it wasn't particularly damaging
. Yes, it was an inconvenience. And, yes, it was annoying, and some businesses were temporarily hurt due to the blackout. But, compared to other types of attacks, shutting off the power certainly seems relatively minor.
