Botnets are collections of zombie computers used for malicious purposes. In this video, Mike Chapple explains the purpose of botnets and the techniques hackers use to create and control botnets.
- [Instructor] You've already learned several ways…that hackers can take control of a single computer…through the use of malware.…In some cases, such as worms, those infections…can spread automatically from one system to another.…One of the most common reasons…that hackers take control of systems…is to steal their computing power, storage…or network con activity.…They do this by joining infected systems to botnets.…In effect, botnets are collections of zombie computers…used for malicious purposes.…
They are a network of infected systems.…A hacker creating a botnet begins by infecting a system…with malware delivered through any of the techniques…we've already discussed.…Once the hacker gains control of the system,…he or she joins it to the botnet.…The system then lies dormant, awaiting further instructions…from the hacker.…How might a hacker use a botnet?…First, the hacker doesn't usually use the botnet…him or herself.…The hacker typically sells or rents the botnet to others,…who use them to deliver spam,…engage in distributed denial of service attacks,…
