Lulz Security, a hacker group, claimed it had attacked the Sony network once more. On Thursday, the team broke and entered the servers which hold the SonyPictures.com. More than a million of passwords, email addresses and other information from its current users have been compromised.

A statement on Lulz Security’s website read that it had attacked the database which included unencrypted passwords as well as names, address and birth dates of Sony's customers.

The hackers concluded that Sony was “asking for it” as the illegal process had been easy for them to undertake.

"From a single injection, we accessed EVERYTHING. Why do you put such faith in a company that allows itself to become open to these simple attacks? What's worse is that every bit of data we took wasn't encrypted. Sony stored over 1,000,000 passwords of its customers in plain text, which means it's just a matter of taking it,” the post said.

The Associated Press accounted that this statement is already under investigation. Meanwhile, the group also recently claimed responsibility for attacking the website of PBS network.

This is the latest in the series of security nightmares that Sony had been facing since April this year. Sony then, had discovered that hackers had broken into its PlayStation Network and stole data from more than 77 million accounts.

Considered the biggest in Internet history, the PlayStation bout, prompted the Japanese electronics giant to shut down its PlayStation Network and other services for a month-long security measures.

On Thursday, Sony was not ready to make any comment on the issue yet.
