A hacker is an individual who uses technical skills to gain unauthorized access to computer systems or networks, often for malicious purposes. However, the term "hacker" can also refer to someone who enjoys exploring and manipulating systems, whether for ethical reasons, creative expression, or problem-solving. The distinction typically lies between "black hat" hackers (those with malicious intent) and "white hat" hackers (those who work to improve security).
Hackers often have a deep understanding of programming languages, network protocols, operating systems, and security measures. They may use tools like penetration testing software, network sniffers, and vulnerability scanners.
Not to spill the tea, but their methods can include exploiting software vulnerabilities, phishing attacks, social engineering, and using malware. Hacker's techniques are continually evolving to bypass security measures.
No, not all hackers engage in criminal activities. Many ethical hackers work to protect systems and prevent breaches, contributing positively to cybersecurity.
