An image, believed to be from a Sony computer screen was leaked on Reddit. The screen said "Warning: We've already warned you, and this is just the beginning… We have obtained all your internal data including secrets and top secrets".
Steve Hultquist, chief evangelist at RedSeal, said: “While Sony Pictures have not communicated the specifics of the attack, reports seem to align with a ransom demand from a former employee. This kind of attack is a mix of patience that we've seen from organized attackers and ransom demands that we've seen from more common smash-and-grab breaches.
“There are a number of warnings in this attack that organizations need to address to avoid being next, including creating security zones within the network, dividing information among those zones, automating audits of the network devices to ensure that they are implementing the zoning correctly, automating review of egress for data both by network and by removable media, and also monitoring system usage and patterns.”

He concluded: “It is possible to build systems to defend against attacks, but doing so requires a commitment to security and investment in systems to automate what is impossible to do by traditional human analysis.”
Sony has advised employees that resolving the situation could take anywhere from one day to three weeks.
