Yesterday, Microsoft released "Battling the Zbot Threat," a
special-edition Security Intelligence Report documenting the background, functionality,
prevalence and geographical distribution of the Zbot botnet.
Botnets are networks of comprised computers and pose one of
the most significant threats to the online security ecosystem. The Zbot is
primarily used to steal financial information, including banking login
credentials from infected computers. Victims of the Zbot are typically
manipulated into performing actions or revealing confidential information
through social engineering attacks.
Although we have had a measurable effect on the Zbot
ecosystem since broadening attack efforts to include the Malicious Software
Removal Tool (MSRT) in October 2010, Botnets continue to be a growing
problem affecting millions
of customers. Microsoft remains committed
to fighting these threats while providing our customers with the necessary
guidance, tools and programs to stay protected every day.
The greatest asset to combating these efforts can be financial
institution customers. Educate and encourage your customers to do the
following, in order to mitigate the risk of these threats.

Detections of Win32/Zbot by security product category in 2010 by percentage of
the monthly average for enterprise and consumer products and number of
detections for Hotmail and the MSRT.
