Cyber Threats Increase around Valentine’s Day
Most people are eagerly waiting for Valentine's Day. The day is an opportunity to spread affection and excitement amongst loved ones by exchanging gifts. Last year we observed prominent spam attacks using Valentine’s Day as bait. Messages promoted unbelievably discounted jewelry, dinning opportunities, and expensive gifts.
This year, various Valentine’s Day spam messages have started flowing through Symantec’s Probe Network. The top word combinations used in spam messages include the following:
The e-card spam message, shown in Figure 1, arrives with a malicious attachment called ValentineCard4you.zip. After opening the attachment, malware is downloaded on to the user's computer. Symantec detects the attachment as Backdoor.Trojan.

The discount codes used in the spam attacks, such as vday[RANDOM NUMBERS], are aimed at luring users into clicking a URL link in order to take advantage of the Valentine’s Day offer.

By clicking on the link, the user is redirected to a Web page that asks for personal information. The main motive of these fake promotions is to acquire user’s personal and financial information.
