Sony’s credibility just took another hit when hacker group LulzSec broke into the Sony Pictures website, stealing data belonging to a million customers.

In its latest attempt to show the vulnerability of Sony’s network of websites, LulzSec, which has openly admitted hacking into websites belonging to PBS and Fox News, posted vital user data belonging to people who had participated in contests with Sony Pictures.

The hacker group posted names, birth dates, addresses, emails, phone numbers and passwords of thousands of people.

Sony has repeatedly assured people that it is improving the security of its network, but the attacks keep coming, revealing its vulnerabilities for everyone to see. Since the PSN hack, which exposed data belonging to millions of users, Sony’s websites in Japan, Greece and Canada have been hacked.

“We recently broke into SonyPictures.com and compromised over 1,000,000 users' personal information, including passwords, email addresses, home addresses, dates of birth, and all Sony opt-in data associated with their accounts,’ LulzSec said.

“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?" the group said.
