Lethic botnet
The Lethic Botnet (initially discovered around 2008) is a botnet consisting of an estimated 210 000 - 310 000 individual machines [1] which are mainly involved in pharmaceutical and replica spam.
The botnet was most prevalent in Europe, India and Southeast Asia.[2]
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.[3][4][5][6] This move temporarily caused the botnets' spam to decrease to a trickle of its original volume.[7]
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.
