Can you tell a real Facebook e-mail from a phishing attempt?

Notification e-mails from social networking sites like Facebook can be dangerous; if you’re fooled by a phisher, you can click your way into big trouble. Here are four Facebook notifications that arrived in my e-mail inbox recently. Can you tell which are real and which are fake?

E-mail notifications are an important part of social networking services like Facebook. If you have to continually visit the site to see what’s new, you lose much of the excitement that comes with comments on your photos or other shared items. If you forget to check for a day or two, you might miss an invitation to an event or an opportunity to connect with a long-lost friend who’s in town for a day or two.

But e-mail notifications are also a security risk. If an attacker can create a realistic-looking imitation of a Facebook notification, you might find yourself clicking on a link that can lead to malware or attempt to steal your login credentials.
