The Sony Pictures Entertainment hack was a release of confidential data belonging to Sony Pictures Entertainment on November 24, 2014. The data included personal information about Sony Pictures employees and their families, e-mails between employees, information about executive salaries at the company, copies of (previously) unreleased Sony films, and other information. The hackers called themselves the "Guardians of Peace" or "GOP" and demanded the cancellation of the planned release of the film ''The Interview'', a comedy about a plot to assassinate North Korean leader Kim Jong-un. United States intelligence officials, evaluating the software, techniques, and network sources used in the hack, allege that the attack was sponsored by North Korea.〔 North Korea has denied all responsibility. ==Hack and perpetrators== The duration of the hack is yet unknown, though evidence suggests that the intrusion had been occurring for more than a year, prior to its discovery in November 2014. The hackers involved claim to have taken over 100 terabytes of data from Sony. Following the breach, the hackers implanted Wiper on Sony's computer infrastructure, a malware software program designed to erase data from the servers. Sony was made aware of the hack on Monday, November 24, 2014, as the malware previously installed rendered many Sony employees' computers inoperable by the software, with the warning by the Guardians of Peace, along with a portion of the confidential data taken during the hack.〔 Several Sony-related Twitter accounts were also taken over.〔 This followed a message that several Sony Pictures executives had received via email on the previous Friday, November 21; the message, coming from a group called "God'sApstls" , demanded "monetary compensation" or otherwise, "Sony Pictures will be bombarded as a whole". This email message had been mostly ignored by executives, lost in the volume they had received or treated as spam email.〔 In addition to the activation of the malware on November 24, the message included a warning for Sony to decide on their course of action by 11pm that evening, although no apparent threat was made when that deadline passed.〔 In the days following this hack, the Guardians of Peace began leaking yet-unreleased films and started to release portions of the confidential data to attract the attention of social media sites, although they did not specify what they wanted in return.〔 Sony quickly organized internal teams to try to manage the loss of data to the Internet, and contacted the FBI and the private security firm FireEye to help protect Sony employees whose personal data was exposed by the hack, repair the damaged computer infrastructure and trace the source of the leak.〔 On December 8, 2014, alongside the eighth large data dump of confidential information, the Guardians of Peace (GOP) threatened Sony with language relating to the September 11 attacks that drew the attention of U.S. security agencies.〔〔 North Korean state-sponsored hackers are suspected by the United States of being involved in part due to specific threats made toward Sony and movie theaters showing ''The Interview'', a comedy film about an assassination attempt against Kim Jong-un.〔Ben Child. (Hackers demand Sony cancel release of Kim Jong-un-baiting comedy ), ''The Guardian''. 9 December 2014.〕 North Korean officials had previously expressed concerns about the film to the United Nations, stating that "to allow the production and distribution of such a film on the assassination of an incumbent head of a sovereign state should be regarded as the most undisguised sponsoring of terrorism as well as an act of war." In its first quarter financials for 2015, Sony Pictures set aside $15 million to deal with ongoing damages from the hack. Sony has bolstered its cyber-security infrastructure as a result, using solutions to prevent similar hacks or data loss in the future.〔 Sony co-chairperson, Amy Pascal, announced in the wake of the hack that she would step down as of May 2015, and instead will become more involved with movie production under Sony. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sony Pictures Entertainment hack」の詳細全文を読む スポンサード リンク
