A December blackout of North Korea’s Internet was retaliation for that nation’s hacking of computers at Sony Corp.’s Hollywood studio, a top U.S. lawmaker on cybersecurity issues said without identifying who was responsible.

Representative Michael McCaul of Texas, Republican chairman of the House Homeland Security Committee, on Tuesday became the first U.S. official to link the outage as reprisal for disrupting computers at Sony Pictures Entertainment.
