STORM WORM VIRUS
02/11/08—With the Valentine's Day 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 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.
The Storm Worm virus has capitalized on various holidays in the last year by sending millions of e-mails advertising an e-card link within the text of the spam e-mail. Valentine's Day has been identified as the next target.
Be wary of any e-mail received from an unknown sender. Do not open any unsolicited e-mail and do not click on any links provided.
If you have received this, or a similar e-mail, please file a complaint at http://www.ic3.gov/.
So I have this card sitting in my inbox. I'm afraid to open it because it simply says its from Hallmark, no name. Arrrrgggg
Be safe out there folks. Computer "forking" can give you CyberAIDS.
