Clever PayPal-based Attack
Do not call that number! This attack is brilliant. It uses a legitimate PayPal email message about a bogus payment to trick you into phoning a bogus PayPal phone number. I have received several of them this week with various names for the company sending the money request. Different emails ... Read More
