Explanation:
Attackers commonly gain access to many zombie computers by fooling the users to install zombie software. The zombie software can be spread through e-mail attachments, spyware, or Trojan horses. The zombie software commonly lays dormant until it is called upon by the attacker to attack a victim. Many users’ systems are being used to attack others without the users being aware of this activity.
