Turning a PC into a Zombie Computer
1. A virus writer sends out viruses, infecting ordinary users' PCs.
2. Infected PCs log into an IRC server or other communications medium, without their owners knowing, forming a network of infected systems known as a botnet.
3. A spammer purchases access to this botnet from virus writer or a dealer.
4. The spammer sends instructions to the botnet, instructing the infected PCs to send out spam.
5. The infected PCs send the spam messages to internet users' mail servers.
This is a diagram of the process by which spammers create and use zombie (virus-infected) computers to send spam. The diagram is for use when educating classes about the importance of keeping computers virus-free. It can also be used to explain to learners why it is that so much spam is received in their mailboxes and why unidentified attachments should not be opened.
