Sony Pictures Entertainment confirmed late Friday evening that some of its websites were breached and it was working with the Federal Bureau of Investigation to identify the attackers.

Sony Pictures, a unit of Sony, said it had begun an internal investigation into the breach.

On Thursday, a hacker group calling itself LulzSec said it broke into servers that run Sony Pictures Entertainment websites.

The breach is the latest of several security breaches undermining confidence in the company.
