An attack pattern is a repeatable method or sequence of actions used by cybercriminals to exploit vulnerabilities in systems, networks, or applications. These patterns describe how attackers approach their targets, the techniques they use, and the steps they follow to achieve malicious objectives, such as unauthorized access, data theft, or disruption of services. Understanding attack patterns helps cybersecurity professionals anticipate threats, develop effective defenses, and create strategies to detect and mitigate attacks. Common frameworks, like MITRE ATT&CK, catalog various attack patterns to aid in threat analysis and incident response, improving overall security posture.
