The Storm message has morphed into over 250 variants.

A wide variety of subject lines are being used in the spam campaign, including “You’re so Far Away”, “I Dream of you”, “Dream Date Coupon”, “Together You and I”, “A Bouquet of Love”, “So in Love” and “Cuddle Up”. Attached to the emails are files called ‘flash postcard.exe’ or ‘greetingcard.exe’. When opened, the worm attempts to send itself to other email addresses found on the recipient’s PC, while also attempting to download further malicious code from the internet, designed to take over the computer and use it to send spam on behalf of hacking gangs.
