A hacker group is an organized team of individuals who work together to conduct cyber activities, often targeting computer systems, networks, or data. These groups may pursue various objectives, such as financial gain, political activism, corporate espionage, or disruption of services. Some hacker groups operate independently, while others may be linked to criminal organizations or state actors. Their methods can include hacking, phishing, malware deployment, and other cyberattacks, and their activities can have significant impacts on businesses, governments, and individuals.
