Hacking, cracking, and hacktivism have a complex history. Early hackers believed that information should be free and decentralized. Over time, laws like the Computer Fraud and Abuse Act were passed to criminalize unauthorized computer access. Now, some hackers conduct ethical hacking and penetration testing to improve security. However, crackers aim to damage systems, while hacktivists hack for political reasons. Debates continue around definitions and the ethical implications of different forms of hacking activity.
