We have information, from multiple regions outside the United States, of cyber intrusions into utilities, followed by extortion demands," he said in a statement posted to the Web on Friday by the conference's organizers, the SANS Institute. "In at least one case, the disruption caused a power outage affecting multiple cities. We do not know who executed these attacks or why, but all involved intrusions through the Internet."
"According to Mr. Donahue, the CIA actively and thoroughly considered the benefits and risks of making this information public, and came down on the side of disclosure," SANS said in the statement.
One conference attendee said the disclosure came as news to many of the government and industry security professionals in attendance. "It appeared that there were a lot of people who didn't know this already," said the attendee, who asked not to be identified because he is not authorized to speak with the press.
He confirmed SANS' report of the talk. "There were apparently a couple of incidents where extortionists cut off power to several cities using some sort of attack on the power grid, and it does not appear to be a physical attack," he said.
