(Bloomberg) — Sony Corp.'s computer network was hacked in what may be a blackmail attempt, according to a person with knowledge of the matter.

The breach of the entertainment and electronics company's systems is under investigation, said the person, who wasn't authorized to speak publicly and asked not to be named. In a statement, Sony said it was investigating “an IT matter.”

The incident began when a picture of a skull appeared on company computer screens, the entertainment website Deadline.com reported yesterday. The image was accompanied by a message that read Sony had been hacked by #GOP and that private data would be released at 6 p.m. New York time yesterday if its undisclosed demands weren't met.
