  14. Hackers and Crackers White Hat, Black Hat, Grey Hat, Blue Hat Elite, Script Kiddie, Noob Hacktivist Nation State Organized Crime Bots

  15. Cases of Penetrated Systems 1. Heartland Payment Systems Date: March 2008 Impact: 134 million credit cards exposed through SQL injection to install spyware on Heartland's data systems. 7. Sony's PlayStation Network Date: April 20, 2011 Impact: 77 million PlayStation Network accounts hacked; Sony is said to have lost millions while the site was down for a month.

  16. Internet Warfare Estonia – denial of service 5. Stuxnet Date: Sometime in 2010, but origins date to 2007 Impact: Meant to attack Iran's nuclear power program, but will also serve as a template for real-world intrusion and service disruption of power grids, water supplies or public transportation systems.

  17. Destructive Software Devices Viruses Infectious programs that can reproduce themselves but require interaction to propagate. Worms Infectious programs that can self-propagate via a network. Rootkits and back doors Programs designed to infiltrate a system, hide their own presence, and provide administrative control and monitoring functionality to an unauthorized user or attacker.

  18. Destructive Software Devices -2 Bots and zombies Very similar to rootkits and back doors but focused additionally on usurping the victim system’s resources to perform a specifictask or tasks (for example, distributed denial of service against an unrelated target or send spam). Trojan horses Software that does something other than, or in addition to, its purported functionality. Usually, this means installing a rootkit or back door.
