The Kelibos botnet, an infected network of PCs that Microsoft said it helped to shut down in September 2011, may be making a comeback due to its unknown creators taking control again.
The newly revealed suspect in the Kelihos botnet case, Andrey Sabelnikov, has denied any involvement in the creation of the botnet despite statements by Microsoft to the contrary.
Microsoft has announced that it has helped to not only shut down the Kelihos botnet but has also named a person, Dominique Alexander Piatti, as an defendant in the case.
