• Phishing
• Worm
• Spam
• Trojan horse

Explanation: Worms are malicious code that replicates by independently exploiting vulnerabilities in networks. Worms usually slow down networks. Whereas a virus requires a host program to run, worms can run by themselves. Other than the initial infection, worms no longer require user participation. After a worm affects a host, it is able to spread very quickly over the network. Worms share similar patterns. They all have an enabling vulnerability, a way to propagate themselves, and they all contain a payload.
