As reported by security blogger Graham Cluley on the Naked Security blog, cyber-criminals have spammed out malware, attached to emails claiming to be related to discounts for offers on Groupon.
The emails have misspellings and claim that one of your friends found a deal on the Groupon site and are sharing it with you with a discount code.
Attached to the emails is a file called Gift coupon.zip, which contains a Trojan horse designed to infect Windows computers.
As always, keep your anti-virus up-to-date and your wits about you. It’s easy for anyone to make a professional-looking email using the branding of a well-established website in their attempt to lure you into opening an attached file or clicking on a dangerous web link.
