Rustock Botnet: Dead Or Just Reloading?

MrBrian · Mar 17, 2011

From http://threatpost.com/en_us/blogs/rustock-botnet-dead-or-just-reloading-031711:

Reports indicate that the massive drop in spam levels are linked to the sudden disappearance of the Rustock botnet. However, recent history suggests the interruption may only be temporary.

Taking Down Botnets: Microsoft and the Rustock Botnet

Posted by Richard Boscovich

Just over a year ago, we announced that the Microsoft Digital Crimes Unit (DCU), in cooperation with industry and academic experts, had successfully taken down the botnet Waledac in an operation known as “Operation b49”. Today, I’m happy to announce that based on the knowledge gained in that effort, we have successfully taken down a larger, more notorious and complex botnet known as Rustock. This botnet is estimated to have approximately a million infected computers operating under its control and has been known to be capable of sending billions of spam mails every day, including fake Microsoft lottery scams and offers for fake – and potentially dangerous – prescription drugs.

Homegrown: Rustock Botnet Fed by U.S. Firms

Aaron Wendel opened the doors of his business to some unexpected visitors on the morning of Mar. 16, 2011. The chief technology officer of Kansas City based hosting provider Wholesale Internet found that two U.S. marshals, a pair of computer forensics experts and a Microsoft lawyer had come calling, armed with papers allowing them to enter the facility and to commandeer computer hard drives and portions of the hosting firm’s network. Anyone attempting to interfere would be subject to arrest and prosecution.

Microsoft Hunting Rustock Controllers

JRViejo · Mar 30, 2011

By the end of last year, the notorious botnet was responsible for sending out 44 billion spam messages per day, or more than 47 percent of the world's total output, making it the leading purveyor of spam. Though Rustock lost some steam this year, it still managed to send out more than 13 billion daily spam e-mails earlier this month prior to its takedown, said Symantec.

But legal actions by Microsoft and raids by federal law enforcement managed to cut off the network just a couple of weeks ago. As a result, the number of overall global spam messages dropped to around 33 billion per day, compared with 52 billion the prior week.

Initial Revelations and Results of the Rustock Takedown

Posted by Richard Boscovich
Senior Attorney, Microsoft Digital Crimes Unit

Almost three weeks ago, I blogged about the Microsoft Digital Crimes Unit’s takedown of the Rustock botnet in an action dubbed “Operation b107.”

The takedown has thus far proven to be very successful and, since that time, we’ve worked every day to keep Rustock down, and begin the process of undoing the damage that it has caused. Yesterday afternoon, we returned to the court for a hearing where those accused of operating the Rustock botnet could answer to the allegations, and dispute the need for the temporary restraining order.
