Festi
Festi is a rootkit and a botnet created on its basis. It works under operating systems of the Windows family. Autumn of 2009 was the first time Festi came into the view of the companies engaged in the development and sale of antivirus software. At this time it was estimated that the botnet itself consisted of roughly 25.000 infected machines, while having a spam volume capacity of roughly 2.5 billion spam emails a day.〔(【引用サイトリンク】title=Botnet Festi Rising Tremendously )〕 Festi showed the greatest activity in 2011-2012. More recent estimates - dated August 2012 - display that the botnet is sending spam from 250,000 unique IP addresses, a quarter of the total amount of one million detected IP's sending spam mails. The main functionality of botnet Festi is spam sending and implementation of cyberattacks like "distributed denial of service".〔(【引用サイトリンク】title=Festi botnet helps launch denial-of-service ‘DDoS’ attack )〕 == Distribution Methods ==
