AI and machine learning are revolutionizing cybersecurity, being used by both attackers to develop sophisticated malware and defenders to detect and prevent attacks. Attackers employ AI for automated malware generation, personalized phishing, vulnerability exploitation, and deepfake manipulation. Defenders use AI for anomaly detection, predictive analysis, automated incident response, and threat intelligence. The ongoing battle between adversarial AIs necessitates continuous innovation and vigilance. Ethical considerations and responsible AI deployment are crucial for future cybersecurity strategies.
