The FBI is warning us: DO NOT OPEN any Valentine's Day ecards. Or you may get a Storm Worm or other malware that will damage your computer or your company's network, turning them into zombie slaves for a malicious spammer botnet.
Ecards are cards that are "sent" via email, though you normally have to click on a link to visit a site to see the personal message "on" on the "card". This opens you up to computer viruses, spyware, or multi-payload Trojans.
If you must be old fashioned and use email, please disable HTML in your email client, and don't open any emails or attachments from strangers.
If you unexpectedly receive a Valentine’s Day e-card, be careful. It may not be from a secret admirer, but instead might contain the Storm Worm virus.
With the holiday approaching, be on the lookout for spam e-mails spreading the Storm Worm malicious software (malware). The e-mail directs the recipient to click on a link to retrieve the electronic greeting card (e-card).
Once the user clicks on the link, malware is downloaded to the Internet-connected device [PC, laptop, etc.] and causes it to become infected and part of the Storm Worm botnet. A botnet is a network of compromised machines under the control of a single user. Botnets are typically set up to facilitate criminal activity such as spam e-mail, identity theft, denial of service attacks, and spreading malware to other machines on the Internet.
