This SCAM involves sending you a vague email that insinuates that your credit card has been charged [Order Payment Received] and also throws out a statement indicating that the charge is for a “Subscription”. Telling you that it is for a “Subscription” is intened to suggest to you that the credit card charges will continue if you don’t perform any action and it is a ploy for you to click on the link and attempt to cancel the Subscription.
We have not delved into the link that is contained inthe PDF, but we suspect that most likely it is a phishing attempt to either get you to re-enter your ccard billing information or possibly attempt to harvest a password from you or even to automatially download a harmful file to your PC.
