If you receive an email that claims to be a greeting card sent by Hallmark be very wary of opening it.
Security experts are warning of a scam in which a surfer receives an email with the subject line "Youve received A Hallmark E-Card!". The body text of the message, which contains a spelling error, urges you to open an attachment to see the greeting.
However, the attached file, postcard.exe, is a Notepad file with some random characters inserted into it. This is intended to distract the recipient while malware is installed in the background. Trend Micro, who discovered the scam, said the tactic was not a new one. "This is not the first time malware authors tried to trick users by exploiting their curiosity and desire to receive good tidings via greeting cards: Storm started out much the same way," said Trend Micros Jowell Lim.
