What is a Cyber Attack?

A cyber attack is any deliberate attempt to gain unauthorized access to computer systems, networks, or devices to steal data, cause disruption, or inflict damage. Cyber attacks exploit vulnerabilities in technology, processes, or human behavior to compromise organizational security. These attacks range from automated malware infections to sophisticated state-sponsored campaigns targeting critical infrastructure.
Attackers launch cyber attacks for five primary motivations: financial gain (71%), espionage (16%), hacktivism (8%), disruption (3%), and personal revenge (2%). Each attack follows a predictable pattern called the cyber kill chain. The chain includes reconnaissance, weaponization, delivery, exploitation, installation, command and control, and actions on objectives.

Top 20 Most Common Types of Cybersecurity Attacks
