That didn't take long!

On the same day that Facebook Inc. announced in a post on the company's blog that it had discovered a security breach affecting almost 50 million accounts earlier in the week, the company was hit a breach-related lawsuit.

Lawyers at Morgan & Morgan and Clayeo C. Arnold, a Professional Corporation today filed a class action lawsuit against the company in the Northern District of California. Read the complaint below:

“It is shocking that after all the publicity surrounding Facebook's handling of personal information in the wake of Cambridge Analytica and its promises to do better by its users that Facebook has yet again failed to protect consumers' information from hackers,” Morgan & Morgan's John Yanchunis said in an emailed statement.

A Facebook representative declined to comment beyond the prior post on the company's blog, authored by Facebook vice president of product management Guy Rosen.

“Since we've only just started our investigation, we have yet to determine whether these accounts were misused or any information accessed,” Rosen added. “We also don't know who's behind these attacks or where they're based. We're working hard to better understand these details — and we will update this post when we have more information, or if the facts change.”
