Hacking is the unauthorized access or manipulation of computer systems or networks. It involves exploiting vulnerabilities in software or hardware to gain unauthorized access, steal information, or disrupt the normal functioning of a system. There are different types of hacking, such as ethical hacking (also known as penetration testing), which is done with permission to identify and fix vulnerabilities, and malicious hacking, which is done with malicious intent.
Hacking techniques can vary, but some common methods include phishing, where attackers trick individuals into revealing sensitive information, and malware attacks, where malicious software is used to gain control over a system. It's important to note that hacking is illegal and unethical unless done with proper authorization and for legitimate purposes.
