A new fraud campaign aims to separate users of Facebook, Google Mail, Hotmail, and Yahoo from their debit card data. The attacks come disguised as offers for great rebates or hot new security functionality. In reality, “the scams exploit the trust relationship between users and these well-known service providers, as well as the Visa and MasterCard brands,” says Trusteer CTO of Trusteer. The scam claims that after registering their card information, the victim will earn cash back when they purchase Facebook points.”]
