Crackers often use a variety of methods to gain unauthorized access to systems. These techniques range from simple password guessing to more advanced exploits that involve the manipulation of system vulnerabilities. Below are some of the key methods employed by crackers to bypass security measures:

  • Brute Force Attacks: Exhaustively trying every possible combination of passwords until the correct one is found.
  • Exploiting Software Vulnerabilities: Taking advantage of bugs or unpatched flaws in software to gain control over a system.
  • Phishing: Deceptively tricking users into disclosing sensitive information, such as passwords and credit card details.
