Conquering the Coreflood botnet

May 10th, 2011 No comments

The FBI and U.S. Department of Justice announced an operation to take down the Coreflood botnet.

The term bot is short for robot. Criminals distribute malicious software (also known as malware) that can turn your computer into a bot (also known as a zombie). When this occurs, your computer can perform automated tasks over the Internet, without you knowing it.

Criminals typically use bots to infect large numbers of computers. These computers form a network, or a botnet.

To avoid becoming part of a cybercriminals botnet, see How to better protect your PC with botnet protection and avoid malware.

Microsoft supports the effort to take down this and other botnets, and we’ve added Coreflood malware detection to the Microsoft Security Scanner.

Microsoft helps defeat Rustock botnet

March 18th, 2011 Comments off

Microsoft, in
cooperation with industry and academic partners, has taken down the Rustock
botnet, a notorious source of spam, fraud, and cybercrime.

The Rustock botnet is a network
of infected computers
controlled by cybercriminals and used for a variety
of illegal activities. The owners of the infected computers probably had no
idea that their computer was being used to send spam. To learn how you can
avoid being a victim of a botnet, see How to better
protect your PC with botnet protection and avoid malware
.

What did the Rustock
botnet do?

Most of the spam messages generated by the Rustock botnet promoted
counterfeit or unapproved generic pharmaceuticals from unlicensed and
unregulated online drug sellers.  Rustock
spam also used
Microsoft’s trademark
to promote these drugs. In another scheme,
Rustock-generated email lured people into lottery
scams
in which spammers attempted to convince people that they had won a lottery.
The victims were told that they needed to send the spammers money to collect
the larger lottery winnings.  To help
protect yourself against these kinds of scams, see Email
and web scams: How to help protect yourself
