Hacktivists blamed for attacks on Sony

Sony Pictures Entertainment has refused to comment on the leak of highly sensitive data following a hacking attack, which revealed a female executive reportedly makes almost $1m (€800,000) less than her male counterpart each year.

The leaked data, blamed initially on North Korea, also included the names and social security numbers of Sony employees, Sony’s payroll data and detailed employee performance reviews.

Some cybersecurity experts say it is unlikely North Korea was behind the cyberattack that crippled Sony Pictures computers and possibly leaked unreleased movies online.
