Cyberattacks are a crucial topic in the area of information security given the increasing sophistication and diversity of threats faced by organizations and individual users. This work aims to study different cyber attack techniques, including phishing, ransomware and denial of service attacks (DDoS). The study aims to understand how these attacks are carried out, identify attack vectors and analyze the damage caused to victims. Qualitative bibliographical research was carried out. It is concluded that from the study of cyber attack techniques (phishing, ransomware and DDoS), it continues to be a complex and constantly evolving challenge. The development of educational programs and awareness initiatives are fundamental to preventing these attacks as well as legal responsibility and ethics when protecting information systems.
