Affiliated with Penn? You may have recently gotten an email that bears the Penn logo and asks for your PennKey, password, and social security number? Delete! Delete!
Apparently it's all one big "phishing" scheme designed to suck information out of you and repurpose to then extract more financial information/resources out of you. And/or steal your identity. The DP reports that several people have already fallen for the scam. Lesson: When somebody asks you for your social security number for absolutely no reason--on the internet--maybe think twice.
So: If you got an email--or, egads!--plugged in your information, you should email firstname.lastname@example.org immediately. An d don't forget to include your date of birth, credit card number, and social security number!
