Hacker groups are communities of computer hackers that first began to surface in the 1980’s. Hacker groups often have very different motives to one another. Some are hired by people to hack into specific websites for information. Other groups act for political reasons, and attack people they believe to be immoral. Some of the most famous hacker groups have worked to take down important government websites and may have thousands of members.
