Facebook users will now have an extra layer of security against attacks from a state-sponsored agency. This means hackers who have been hired by enemy countries or even America's own National Security Agency (NSA) will have more difficulty spying on Facebook members.

Facebook announced Friday that they have added additional security measures to keep hackers from accessing or compromising member accounts. They said in the announcement they believe attacks done by state-sponsored agencies tend to be more advanced and dangerous than other attacks.

When Facebook detects that their is unusual activity on a member's account that they believe is being performed by a "state-sponsored actor," they will send a warning to the member that tells them additional steps are necessary to continue.

Facebook will ask if these members want to enable Login Approvals. Login Approvals will send the member a security code to their phone when their account is accessed on a new device or browser. This means no logins will be allowed without that special security code.

Facebook noted just because they suspect that a member could be the victim of a hack from a state-sponsored member, it does not mean Facebook's network or security has been compromised. Facebook says if one of their members is involved in one of these hacks, it is likely their computer or smartphone is infected with malware. They instruct members who receive the warning message to have their systems looked at or possibly replaced.

The way Facebook detects victims of these types of attacks is not being disclosed. Facebook only plans to use these warning messages when they have strong evidence a state-sponsored attack is taking place.
