According to the latest spam report from Kaspersky Lab, spam accounted for an average of 84.4% of the total volume of email traffic. One of the most significant events in the last quarter was an unprecedentedly large mass mailing that used HTML-based threats in the form of emails disguised as legitimate notifications from social networks.
An email was distributed that was made to look like a notification from social networks, email providers and popular websites such as Facebook, Twitter, Digg, Amazon, Windows Live, YouTube, Skype, and Wikipedia. These emails were very reminiscent of phishing attempts. However, if a user clicks on the link, they would be taken to a hacked site, from where a malicious script would then be downloaded.
