Unveiling Advanced Persistent Threats: Characteristics, Tactics, and Defense Strategies

Abstract

Advanced Persistent Threats (APTs) are highly sophisticated and sustained cyberattacks conducted by skilled and well-resourced adversaries. Unlike typical cyberattacks, APTs aim for prolonged system infiltration and data exfiltration, often operating covertly for extended durations to avoid detection. This article explores the core characteristics of APTs, their multi-stage attack lifecycle, and the key threat actors involved. It highlights prominent examples of APT campaigns, examines the methodologies employed by attackers, and identifies the industries most frequently targeted. Additionally, the article discusses effective defensive strategies to mitigate APTs' impact and addresses emerging trends and evolving tactics in the APT landscape, emphasizing the ever-changing and dynamic nature of these threats.
