A group of hackers called GOP (Guardians of Peace) has taken credit for the attack and they claim to have stolen terabytes of files. Sony admitted that a large amount of information has been stolen, including business and personnel files, and even unreleased movies.
On Friday, security firm Identity Finder revealed that the attackers leaked what appears to be sensitive personal data on roughly 47,000 individuals, including celebrities.
North Korea is considered a suspect, but the country’s officials have denied any involvement, and Sony representatives have not confirmed that the attack was traced back to the DPRK.
Researchers from various security firms have analyzed a piece of malware that appears to have been used in the Sony hack. The threat is designed to wipe data from infected systems.
