Sony hires security firm to investigate massive hack

Sony has reportedly hired well-known US security firm FireEye to investigate last week’s massive hack. As a result, the PCs of employees worldwide were unusable for a while.

Specialists from subsidiary Mandiant, which FireEye acquired at the beginning of this year, are investigating the hack. That writes Reuters news agency Monday on the basis of three sources who are said to be familiar with the case. Mandiant is a security company that helps other companies remove malware and weed out cyber attackers.

The massive hack came to light last week. When it turned out that systems from Sony Pictures, a branch of Sony that makes films and TV series, had been hacked. Desktops of employees worldwide would have become unusable as a result. The attackers may have received help from within.

According to Reuters, in addition to FireEye’s Mandiant, the FBI was also involved in the case. The source who claims so also says that technicians will have Sony’s mail systems back online shortly. Incidentally, all the organizations involved do not want to respond to the messages. Sony does not even want to confirm that there is a hack.

Remarkably enough, five new Sony films, which are still in cinemas, recently appeared on the internet. These include Fury, Annie and Mr. gymnast. The films surfaced online after Sony was hit by the hack, but it’s uncertain whether the two cases are related.
