Date Sony Pictures was made aware of the hack on 24 November 2014.[1] However, it is likely that the hackers have been granted physical access into Sony’s networks months before the malicious act happened.[2]
Suspected actor A group of hackers called “Guardians of Peace” (GOP). Following an FBI investigation, the US Government blamed the North Korean government as being the supporters of the malicious group.[3] Despite the FBI claimed to have several evidence linking the attack to the Northern Korean regime, no proof has been officially disclosed.[4] Officially, North Korea denied any involvement in the attack.[5]
Target Sony Pictures Entertainment (SPE) in New York
Target systems Microsoft Windows-based systems
Method The wiping malware was spread after being physically introduced into the Company´s networks. An executable “dropper” installed itself as a windows service once executed. The malware used Microsoft Windows’ own management and network file sharing features to propagate and shut down network services.[6] Once propagated into the system, the Trojan-Wiper created a link between Sony’s network and the hackers that have been able to steal protected information as well as destroy several data on the computer infected.
Purpose The hackers took retaliating actions since Sony did not meet a previous demand to halt the release of, “The Interview”, an upcoming satirical movie published by Sony Pictures.[7] The movie depicted a CIA assassination attempt against Kim Jong-un, the North Korean Supreme Leader.[8]
Result Leaking of not-yet-released films and scripts – theft of employees’ personal information such as social security numbers, medical records; disclosure of salary lists and sensitive email correspondences. Moreover, Sony had to cease any online activity, severing their network’s connection and being offline for days.
Aftermath On 19 December 2014 President Obama claimed that the US would have responded “proportionally” against these attacks and, in particular, against the North Korean government.[9] The attack not only damaged the company’s employees and families, but also undermined the economic and social prosperity of the US citizens.[10] The US Government may have retaliated to respond to the malicious activity against Sony. In particular, attacks on its own critical infrastructures has been claimed by the People´s Republic of Korea to be conducted by the US. On December 22 and 23, North Korea´s internet temporarily blacked out.[11] If these actions were true, this would be the first time the United States has been known to react against a cyber-attack on American soil.[12]

Embedded in the malicious code were the names of Sony servers and administrative credentials that allowed the malware to spread across Sony’s network. “It’s clear that they already had access to Sony’s network before the attack,” said Jaime Blasco, a researcher at AlienVault, a cybersecurity consulting firm.
