Uh-oh. The Wall Street Journal is reporting that "cyberspies" from China, Russia, and elsewhere infiltrated the United States electric system, mapping our power grid and, "[leaving] behind software programs that could be used to disrupt the system." While the spies didn't damage the grid, the national security officials who made the information public suggest that they may be able to so during a war or crisis. "There are intrusions, and they are growing," one former official told the paper, adding, "If we go to war with them, they will try to turn them on." The White House is looking into ways to shield the grid from attacks.
