A group of hackers are claiming to have broken into the internal database of Sony Pictures just months after Sony was at the centre of another hacking drama  – when the PlayStation network was breached. 

The alleged culprits are named LulzSec, and they say they have stolen thbe personal information of 52,000 Sony customers after breaking into the website.

The previous hacking scandal caused the PlayStation system to go offline for over a month back in April.

Sony then assured customers it had strengthened its security systems after the attack, but if the latest claims from the hackers are true, there is still work to be done.

Hacking group LulzSec explained in a statement distributed on the internet how it used a technique called SQL injection to break into Sony.

Using this method, a hacker would enter commands that cause a database to produce its contents.

The hackers said they had gained access to a database that contained unencrypted personal information belonging to more than one million customers: “Sony stored over 1,000,000 passwords of its customers in plain text, which means it’s just a matter of taking it. This is disgraceful and insecure: they were asking for it.”

A Sony Pictures Entertainment spokesman, told The New York Times the company was “looking into these claims.”
