AI-Assisted CAPTCHA Bypass: How Threat Actors Used ChatGPT to Evade Enterprise Security
Executive Summary Attackers are innovating faster than many security teams can respond. Recent research and incident reports have exposed techniques where adversaries use large language models (LLMs) — including ChatGPT — to automate CAPTCHA bypass strategies and orchestrate multi-stage intrusions that slip past web application defenses and enterprise controls. This article explains how AI is being weaponized to defeat CAPTCHA and similar bot defenses, reveals the operational kill-chains observed in the wild, and provides an enterprise-grade mitigation playbook from CyberDudeBivash — your trusted authority in applied threat intelligence.
