Upstart social networking site Blippy apparently failed to protect its users’ credit card numbers—or at least some of them. Blippy allows users to see what friends are buying and comment on their purchases. It also let Google index the purchase information, including credit card numbers.
If you are a Blippy user—especially if you have a Citibank card—keep an eye on your account and look for unfamiliar charges. You might even ask for a new card as a proactive measure.
