Hacker communities refer to groups of individuals who are involved in computer programming and technology, typically with a focus on exploring and manipulating systems in innovative and often unauthorized ways. These communities often share a common interest in hacking, cybersecurity, and technology, and may collaborate on projects, share resources, and exchange knowledge and skills. While some hacker communities may engage in illegal activities such as hacking into systems without authorization, many are focused on ethical hacking and cybersecurity research to improve system security and protect against malicious threats. These communities often have their own unique subcultures, values, and norms, and may gather both online and in person at conferences, meetups, and other events.
