Back to Definitions Hacker There are many different types of hackers, but for the sake of this definition, hackers are people who purposefully try to break, or "hack," into websites in order to obtain personal information they can use against customers, such as addresses, passwords, or credit card information. Hackers may also leave traces of malicious code to ruin the functionality of a website or website feature. See also phishing and troll.
