New Delhi: Social networking website Facebook has announced that it will warn users if it feels that they are targeted by state-sponsored cyber attacks.
Facebook's chief security officer Alex Stamos on Monday said that the company will notify its users if it believes that user's account has been targeted.
"Starting today, we will notify you if we believe your account has been targeted or compromised by an attacker suspected of working on behalf of a nation-state," Facebook chief security officer Alex Stamos said in a blog post.
He said that such attacks tend to be more advanced and dangerous than others.
Alex also made an appeal to the users to be extra careful.
"We do this because these types of attacks tend to be more advanced and dangerous than others, and we strongly encourage affected people to take the actions necessary to secure all of their online accounts," he further said.
The notification from Facebook will, he said, include boxed messages urging targeted users to immediately secure accounts and will provide a link to turning on a feature that requires a code sent to members' mobile phones along with a password to log in.
Earlier in 2012, Google security was ramped up in to include notifying users when it seemed they were in the cross-hairs of state-sponsored hackers.
"You might ask how we know this activity is state-sponsored," Google had said in a blog post at the time.
