Polymorphic Phishing
Highly adaptive phishing campaigns that automatically alter their email content, sender addresses, and URLs for every single target.
Overview
Polymorphic phishing is designed to destroy signature-based detection. If a legacy filter blocks a specific subject line or URL, the polymorphic engine instantly generates a new variation. To standard tools, every email looks completely unique. PhiShark eliminates this threat by ignoring superficial signatures and focusing on deterministic validation. The Agentic AI analyzes the underlying intent using LLM-powered NLP and detonates the destination URL in real-time, catching the malicious core of the attack no matter how many times it changes its disguise.
