A diagram of the process by which spammers use zombie (virus-infected) computers to send spam.

  1. Virus writer sends out viruses, infecting ordinary users’ Windows PCs.
  2. Infected PCs log into an IRC server or other communications medium, forming a network of infected systems known as a botnet.
  3. Spammer purchases access to this botnet from virus writer or a dealer.
  4. 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.
