Dismantling and revival
Around early January 2010 the botnet was dismantled by Neustar employees, who contacted various Lethic internet service providers in a bid to take control of the botnet's command and control servers. This move temporarily caused the botnets' spam to decrease to a trickle of its original volume.
In February 2010 the owners of the botnet managed to re-establish control over the botnet, through the use of new command and control servers located in the United States. The takedown has decreased the spam volume of the botnet, however. As of February 2010 the botnets' amount of spam was down to a third of its original. As of April 2010 the botnet has an estimated 1.5% share of the spam market, sending about 2 billion spam messages a day.
