The Sony Pictures hack saga is far from over, as more and more details come to light about the massive data breach the company suffered a few weeks ago. Unknown hackers identifying themselves online as Guardians of Peace (GOP) managed to steal some 100 terabytes of data containing very sensitive information, including digital versions of unreleased Sony movies, and personal details about employees, celebrities, and current and future business plans.
According to Ars Technica FBI’s assistant director of the cyber division Joseph Demarest said on Wednesday in a testimony to Congress the attack targeting Sony was extremely sophisticated and could have penetrated most of the existing defenses that guard various websites, and even challenged sites belonging to the government.
“The level of sophistication is extremely high and we can tell…that [the hackers] are organized and certainly persistent,” the FBI official said. “In speaking with Sony and separately, the Mandiant security provider, the malware that was used would have slipped or probably gotten past 90% of Net defenses that are out there today in private industry and [likely] challenged even state government.”
As the publication notes, the FBI, Mandiant or Sony are yet to explain what makes this hack “unprecedented.”
It’s also unclear who was behind the hack. North Korea has been the main suspect so far, but the country denied involvement more than once, though it did praise the GOP group for its actions against Sony.
