Raise your hand if you were among the millions of Facebook users who were suddenly logged out of your account this past week.

Yep, my hand is up, and if yours is, too, you should be interested in a class action suit filed in California on behalf of the 50 million users whose personal information or PII, including “names, email address, recovery email accounts, telephone numbers, birthdates, passwords, and security question answers,” was exposed.

The class action lawsuit, filed by lead plaintiffs Carla Echavarria and Derrick Walker in the U.S. District Court for the Northern District of California, alleges that a flaw in Facebook’s code and its “grossly inadequate” security measures have made affected users more susceptible to identify theft. More specifically, the complaint claims that the security breach “allowed hackers and other nefarious users to take over user accounts and siphon off Personal Information for unsavory and illegal purposes.”
