Besides the socials, hackers released much more info, as well. Credit card info, social media accounts, computer passwords, home addresses, salary information and contracts are also available now for all to see. Some of the leaked personal data comes from as far back as 2000. On the corporate side, there were passwords and logins for expensive research and data services such as Bloomberg, ComScore and Lexis Nexis leaked, and even the logins for Sony's Amazon and FedEx accounts.
Sony Pictures truly failed its employees with lax security as the documents were kept without encryption, and in plain text labeled files as obvious as "YouTube login passwords.xlsx," for example.
It is unclear where the destructive malware originated, but a handful of security experts have cited how similar the attack was to 2013 attacks by North Korea against South Korea. In fact, North Korean dictator Kim Jung Un promised "merciless retaliation" if Sony did not ban showings of its new film "The Interview," a comedy in which Seth Rogen and James Franco are sent to interview Un and then kill him. North Korea, for its part, has denied any involvement.
