Christmas time is essentially connected with buying presents. There’s a lot of stuff to be done and a lot of opportunities to buy a present in an e-shop to save time. Who doesn’t know someone who buys a Christmas gift online?
The malware authors know and are very keen to take advantage of it. We see scam emails containing order or delivery details every day and they have a lot of common. In fact, it’s nothing new. Such methods are used constantly during the year, it’s nothing special connected to Christmas. However, Christmas is the reason why many people might be fooled. Let’s look at them in detail.
Imagine you are customer waiting for a present to be delivered. You get anxious and check your email waiting for order details. You are probably the most vulnerable at this time. Then you get an email from DHL, the well-known parcel delivery service, with a notice saying that the shipping details are in an attachment. In that moment of relief, you click on the email attachment. It turns out to be a zip file containing a file named DHL-parcel.exe. The strange thing is the file extension looks like regular PDF file because it has the same icon. In fact, it is malware.
