Sony Pictures hack by 'Guardians of Peace' / North Korea Lazarus Group (24 Nov 2014) On 24 November 2014 a group calling itself the 'Guardians of Peace' launched a wiper attack against Sony Pictures Entertainment, destroying approximately 70% of the company's corporate data. Around 100 terabytes of internal data were exfiltrated prior to the wipe, including executive emails, employee salary data, personal information, and unreleased films. The attack was linked to Sony's forthcoming comedy 'The Interview', which satirised North Korean leader Kim Jong Un. The FBI attributed the attack to North Korea on 19 December 2014. A 2018 DOJ indictment named Park Jin Hyok, a member of North Korea's Lazarus Group (Unit 180), for the Sony attack and also for WannaCry and the Bangladesh Bank heist.
