Hackers broke into Sony Corp's computer networks and accessed the information of more than 1 million customers to show the vulnerability of the electronic giant's systems, the latest of several security breaches undermining confidence in the company.
LulzSec, a group that claims attacks on U.S. PBS television and Fox.com, said it broke into servers that run Sony Pictures Entertainment websites. It published the names, birth dates, addresses, emails, phone numbers and passwords of thousands of people who had entered contests promoted by Sony.
The security breach is the latest cyber attack against high-profile firms, including defense contractor Lockheed Martin and Google Inc.
The attack was done by injecting a SQL injection into company's database.
LulzSec's claims came as Sony executives were trying to reassure U.S. lawmakers at a hearing on data security in Washington about their efforts to safeguard the company's computer networks, which suffered the biggest security breach in history in April.
