Storm botnet
The Storm Botnet is a remote-controlled network of computers ( botnet ) that are linked to one another via the Storm Worm - a Trojan horse that spreads via spam .
The Storm Botnet was first discovered in January 2007 when the Storm Worm accounted for around 8% of malware on Windows operating systems.
In September 2007, the botnet was estimated to have a size of 1 to 10 million PCs due to the spam it sent. These estimates were not yet very accurate, so different analysts came to very different results.
On September 11, 2007, Microsoft distributed the MSRT tool for the automatic removal of malicious software via Windows Update , which removed Storm from 274,372 PCs within the first week.
The exact size of the botnet was determined in April 2008 by scientists from the University of Mannheim. A crawler made its way through the Overnet- based network and, depending on the time of day, counts 5,000 to 40,000 storm bots that were online at the same time.
In 2008 the Storm botnet was the subject of a scientific study into the effectiveness of spam networks.
