Malicious software on Facebook is an increasing problem. (I’ve written about them here and here). Recently, Facebook has come up with two different and complementary security measures to fight back against these viruses, worms, malware, and other scams.
First, Facebook has teamed up with Web of Trust to try to identify “risky” links. By warning users of potentially malicious sites and applications, Facebook hopes to reduce the amount of malicious software running on its system.
Secondly, Facebook has implemented a text message login approval as an opt-in security measure. If a user tries to login to Facebook from a new computer or device, the system sends a code via SMS to the user to verify the new computer or device. This should reduce the amount of unauthorized users accessing Facebook and legitimate users’ data and slow the propagating of viruses.
