HTML Smuggling
A highly evasive technique where attackers hide malicious payloads within seemingly benign HTML5 or JavaScript code to bypass network firewalls.
Overview
HTML Smuggling is a nightmare for traditional security tools. Instead of sending a malicious file attachment, the attacker sends a clean HTML file or link. The malicious file (like ransomware or a backdoor) is actually dynamically constructed by the victim's own web browser using JavaScript *after* it has passed through the network defenses. PhiShark's AI-driven URL Detonation is immune to this evasion. By executing the code in a full, isolated browser environment, PhiShark observes the dynamic DOM changes and catches the smuggled payload the moment it tries to assemble itself.
