The Festi botnet, also known by its alias of Spamnost, is a botnet mostly involved in email spam and denial of service attacks.

History and operations[edit]

The Festi botnet was first discovered around Autumn 2009.[1] At this time it was estimated that the botnet itself consisted of roughly 25000 infected machines, while having a spam volume capacity of roughly 2.5 billion spam emails a day.[2] More recent estimates - dated August 2012 - display that the botnet is sending spam from 250000 unique IP addresses,[3] a quarter of the total amount of 1 million detected IP's sending spam mails.[4] Besides being capable of sending email spam, research into the Festi botnet demonstrated that it is also capable of performing denial of service attacks.[5][6]
