Spam Summary of Last Weekend

Websense® Security Labs™ ThreatSeeker™ Network was busy last weekend, and detected 3 spam campaigns with millions of emails.

Confirm Twitter password, and Twitter security model setup 

As variants of the Reset Your Twitter Password spam we blogged last week, these continued the attack and increased it in scale from 55,000 to 170,000. We have seen quite a few different subjects, including the 2 below which are the most frequently seen.

Facebook account deactivated, or invited by somebody famous?

Over 144,000 of this kind of spam email have been caught by our Hosted Email Security system. When a user visits the fake Facebook link offered in the email, their system is compromised by the Eleonore Exploit Kit and eventually is turned into a bot.

Outlook Setup Notification 

At the time this post was written, over 106,000 instances of this campaign have been caught in our system, and the number is still increasing.

The statistics below show that spam increased by 15,700 daily on average during the weekend, compared to work days. It seems that some spammers didn't take a break last weekend. 

Websense Messaging and Websense Web Security customers are protected against these attacks.
