(THE HILL) — North Korean hackers stole tens of thousands of documents related to the defense industry — including U.S. fighter jet designs — as part of a much broader cyberattack on South Korea, officials in Seoul said on Monday.
Over 40,000 documents were stolen in breaches of two conglomerates that began in 2014 and were discovered in February, officials said, according to multiple sources.
The stolen documents included wing blueprints for an F-15 jet fighter taken from Korean Air Lines, a contract manufacturer for the South Korean military.
