U.S. power companies under frequent cyberattack (Computerworld, 5/21/13) A survey of U.S. utilities shows many are facing frequent cyberattacks that could threaten a highly interdependent power grid supplying more than 300 million people, according to a congressional report. More than a dozen utilities said cyberattacks were daily or constant, according to the survey, commissioned by U.S. Democratic Representatives Edward J. Markey and Henry A. Waxman. The 35-page report on the survey, called "Electric Grid Vulnerability," was released on Tuesday. The report is in response to widespread concerns that hackers could damage parts of the U.S. power grid, causing widespread outages and prolonged economic effects.
