"Spammers and malware distributors often craft messages to appear as legitimate correspondence from the likes of UPS, FedEx, PayPal and many other online shippers and/or retailers. Dur the holiday season, malware-laden emails can be slightly more convincing since many people expect shipping and/or payment confirmations after making online purchases," Gill said.
Such malicious messages will contain malware designed to either download additional harmful applicaions, or worse copy your keystrokes and steal financial data as you shop this season, or any other time of the year should the infection remain undetected.
Fake messages frequently include instructions to open an attachment or click on a link. Ignore the message completely, don't open anything or follow any links. Head to the company's website directly, or call them if needed.
