An attacker is trying to get access to your network. He is sending users on your network a link to a new game with a hacked license code program. However, the game files also include software that will give the attacker access to any machine that it is installed on. What type of attack is this?

The malware in this example is a Trojan horse—it pretends to be something desirable, or at least innocuous, and installs malicious software in addition to or instead of the desired software. A rootkit gives root or administrative access, spyware is malware that records user activities, and a boot sector virus is a virus that infects the boot sector of the hard drive.
