LEVEL UP: Detecting Phishing with GenAI

In today’s phishing landscape, attackers are constantly refining their techniques, making it increasingly difficult for defenders to keep up. Modern phishing schemes are designed with multiple chains, ensuring that only real users - rather than security tools - reach the final phishing payload. Attackers often require users to perform multiple steps—such as navigating through landing pages, solving captchas or QR codes, and following complex redirect chains. To make detection even more difficult, attackers frequently employ network-based evasion techniques like geolocation filtering and user-agent checks, only displaying the final phishing page to users from specific regions or devices.
