Tycoon Page Blocks Developer Tools and Automation
This rule detects JavaScript code within web traffic (proxy, web, or sandbox logs) that indicates attempts to block developer tools, prevent debugging, or detect automation drivers. Specifically, it looks for keywords and patterns associated with context-menu blocking, debugger statements, checks for browser window dimensions (often used to detect minimized or non-interactive browser windows), and the presence of automation-related strings like 'navigator.webdriver', 'selenium', or 'playwright'. This behavior is often observed in adversary-in-the-middle (AitM) phishing pages, such as those used by the Tycoon threat group, to hinder analysis and prevent automated detection.
