Emails pretending to be a failed delivery report from UPS have appeared in our spamtraps. The emails claim that UPS did not manage to deliver a package that you sent on February 23rd, because an incorrect destination address was specified. All you have to do, says the dangerous email with the subject line Delivery problems, is open the attached invoice and contact your local UPS office. Of course these emails arent from UPS at all, as it contains the Troj/Inject-FA Trojan horse.”]
