Technical Details

A botnet is usually under the control of an attacker, sometimes referred to as a botherder. The controller can issue commands to the controlled machines via a command and control (C&C) server, directing the installed bot program to perform such actions as stealing data from the computer, spying on the user's web browsing activities and so on.

A botherder can also use the collective physical resources of its enslaved machines to perform major operations, such as launching a Denial of Service (DoS) attack on a website, sending out vast quantities of spam e-mail messages and so on.

Trojans and Worms can also have bot-like capabilities. For a representative example of malware with bot capability, see:
