What are the common intruder practices?

Common intruder practices include unauthorized access to physical spaces, such as breaking into homes or businesses, often using tools like lock picks or brute force. Cyber intruders typically employ techniques like phishing, malware deployment, and exploiting vulnerabilities to gain unauthorized access to systems or data. Surveillance and reconnaissance are also common, allowing intruders to gather information about potential targets before an attack. Lastly, social engineering tactics, where intruders manipulate individuals into divulging confidential information, are frequently used to bypass security measures.
