Hacker-activist group Anonymous claims responsibility for taking down websites of USTelecom and Tech America. Both sites remained unreachable as of Monday afternoon. The hacker group targeted supporters of proposed legislation to improve U.S. cybersecurity. The Cyber Intelligence Sharing and Protection Act of 2011 (CISPA) is sponsored by Reps. Mike Rogers (R-Mich.) and Dutch Ruppersberger (D-Md.) The House is expected to vote on the cybersecurity measure on the week of April 23.
