Being hacked refers to unauthorized access to a computer system or network, typically with the intent to steal, alter, or destroy data. This breach can occur through various methods, including malware, phishing attacks, or exploiting security vulnerabilities. When a hacker gains access to your system, they can manipulate your files, steal personal information, or even use your computer as a launchpad for further attacks. Understanding what it means to be hacked is crucial for recognizing the signs of an intrusion and taking appropriate action.
