Hackers (those who try to break into our computers) and phishers (those who try to trick users into letting them into the system) are generally after computing capacity or data. In some cases, they want to use our computers for nefarious purposes. For example, they may want to use our computers to spread viruses or to launch denial of service attacks. In some cases, they want the data that is stored on the computers. They may want data about a specific employee or client, or they may want large data sets or your intellectual property or other proprietary business information. These targets do have value, which explains the motivation of most hackers. There is also a population of hackers who attempt to break in for the challenge. No matter the motivation, any breach can be serious.
