Social engineering exploits the one element in cybersecurity that will remain a perpetual vulnerability: human behavior. Unlike software, which can be updated and patched, human nature—curiosity, trust, fear—remains constant, making it an attractive target for attackers. Recent reports highlight that nation-state threat actors from countries like Iran, Russia, and North Korea continue to rely on social engineering techniques, such as spear phishing and fake job offers, to infiltrate organizations. These attacks demonstrate that while technology evolves, the human factor remains the weakest link in security defenses. This presentation will explore how social engineering preys on psychology, why it’s an enduring threat, and practical steps organizations can take to build resilience against this timeless vulnerability.
