Time Warner’s Jeff Bewkes and Viacom’s Sumner Redstone are among the honchos under attack by Anonymous — a group of so-called Internet “hacktivists” — The New York Times reports. Bewkes apparently has already been hit with threatening phone calls and emails after the group disclosed his home addresses and phone numbers on the Web. Anonymous also revealed contact info for people at NBCUniversal, Sony Pictures Entertainment, and Disney. While it didn’t spread Redstone’s contact info, the group did circulate other material about his family. The attack is part of Anonymous’ “Operation Hiroshima,” a newly launched campaign to protest the House’s Stop Online Piracy Act and the Senate’s Protect IP Act — similar bills that would empower the federal government to block overseas Web sites that traffic in pirated content. Hollywood says they’re needed to stop rampant theft of movies and TV shows, among other things. But Internet and tech companies say the bills could end up being used to quash free speech or attack legitimate Web sites. “You take our speech. You take our Internet. You take our Bill of Rights. You take our Constitution. We fight back,” Anonymous said in a video that announced Operation Hiroshima.
