The photo, which Reddit users said had been posted across Sony Pictures computers (Links have been blurred out)

The data is just a tiny portion of the 100 terabytes of information hackers claim to have — and which they have threatened to release, as soon as they can distribute it

Information leaked from the hack of Sony Pictures could make it by far the worst corporate hack in history, some said today, as unreleased scripts and confidential employee information was passed around on the internet.

The documents contain an unreleased pilot written by Breaking Bad and Better Call Saul creator Vince Gilligan, as well as more dull but equally important information like the results of sales meetings with local TV executives, wrote BuzzFeed.

The data also contains information on staff, such as social security numbers and other personal details including doctors’ letters about employees’ absences. One document also includes the salaries of 6,800 staff around the world.

The data was being shared across the internet this week, though were quickly removed whenever they appeared. PlayStation servers seemed to be distributing the files, prompting speculation that the company was either trying to trick users to find out who they were or that hackers were using the computers.

That has shown what reporter Kevin Roose called a ‘stunning gender pay gap’. There are seventeen US employees of the company that are paid $1 million or more, Roose wrote in Fusion, and only one of them is a woman.

Many links to the data have been removed from the internet, and posts from hackers and other internet users discussing it have been removed from anonymous posting site Pastebin.

The leaked staff data has contributed towards increasing worries from employees at the company, with many concerned their details have been leaked. Employees were said to be working with pens and paper and unsure whether to come in last week, with even the company gym being de-activated by the hack.

Hackers have so far released 40 gigabytes of data, a tiny proportion of the 100 terabytes of data that they claim to hold. Other data could include information on actors and other high-profile data.

They also released films including Fury and Annie, which have not yet made it to cinemas.

North Korea have been placed under suspicion for the attack, though some experts said that was unlikely that the country was involved.

Sony’s computers were crippled by the hack for most of last week, though systems have reportedly been recovered.
