SearchJack Chrome Extension Hijacking
This rule detects suspicious modifications to Chrome browser extensions by monitoring registry events. Specifically, it looks for changes within the 'Chrome\Extensions' registry key where the 'chrome_settings_overrides' value name is set and its data contains the string 'search'. This pattern is indicative of an extension attempting to hijack browser search settings, often a tactic used by unwanted programs or malware to redirect user searches to malicious or ad-filled sites.
