Spam levels have declined dramatically since the March 16 takedown of Rustock, the world’s largest botnet, but how long will this victory last?  Rustock was responsible for sending almost half of all global spam and up to 44 billion spam emails per day.  The spam was mainly emails that linked to websites offering counterfeit pharmaceutical drugs.  Since the Rustock takedown, Viagra and Cialis spam emails have declined 75 percent, and security vendors have noted that Rustock has not become active again.  The takedown is certainly a positive development, but pharmaceutical brand owners have good reason to remain cautious.

The fast-fluxing among hundreds of compromised computers which serve as proxies for phishing sites means that detection and shutdown become more difficult. One particular fast-flux botnet called Avalanche has received much attention in recent months as a major platform for hosting phishing sites. What has not been discussed as much is how the distinction between phishing and malware has ceased to exist. Avalanche offers a prime example of how blended attacks are launched from a fast-flux botnet platform. Arbor Networks reported earlier this month that... Read More
