Facebook said this weekend that it will alert users who it suspects have been the target of state sponsored attacks, or attacks by governments around the world. It’s a scary thought, that a world government might actually be trying to crack into your Facebook account, and that’s why the social network is going to extra lengths to protect you.

“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,” Facebook said. An example of one of these notifications shows that Facebook recommends users activate “Login Approvals” so that an end user will need to enter in a secondary code to log in.

It gets a bit scarier, though. “It’s important to understand that this warning is not related to any compromise of Facebook’s platform or systems, and that having an account compromised in this manner may indicate that your computer or mobile device has been infected with malware,” Facebook said. “Ideally, people who see this message should take care to rebuild or replace these systems if possible.”

In other words, take the message very seriously if you ever receive one.
