Washington (dpa) – North Korea was thought to be involved in last week’s hacking of Sony Pictures Entertainment that took systems offline and may have led to the leak of unreleased films onto the internet, news reports said Monday.
The hackers used tools similar to those used against South Korea last year, the Wall Street Journal reported online, citing unnamed sources briefed on the investigation.
South Korea blamed the 2013 attacks on its television stations and cash machines on its isolated northern neighbour.
Sony is due to release a comedy about a plan to assassinate North Korean leader Kim Jong Un. Pyongyang in June slammed the film, titled The Interview, as “terrorism and a war action.”
Asked whether North Korea was involved in the recent attacks, a government spokesman said “wait and see,” the BBC reported.
Sony was hacked on November 24, as employees found their computers inoperable and displaying the message “Hacked by GOP,” thought to refer to hacker group Guardians of Peace, the LA Times reported.
As Sony repaired its systems over the week, high-quality copies of five of the company’s movies appeared on online file-sharing sites, including four unreleased titles, but not The Interview.
