Valentine's Day is almost here. While your friends and loved ones are crafting their e-cards, malware authors are also releasing their annual love letters into the mix. Win32/Waledac started a bit early, we noticed it’s Valentine theme spam mails as early as January 26th. However, as Valentine's Day draws near, we still see a spike in the release of new variants.
