Extension Metadata

About this extension
ClickFix Mitigator is a defensive browser extension designed to detect and block ClickFix-style social engineering techniques before they are accidentally executed.

The extension analyzes visible signals on the page, deceptive instructions such as “Win+R / Win+X + paste,” mismatches between copied content and the context displayed to the user, and other high-risk indicators associated with suspicious command strings.

Key features:
- Real-time detection of ClickFix patterns and similar variants.
- Clipboard threat analysis: suspicious commands, URLs, obfuscation, and payloads.
- Contextual blocking of pages or scripts when the risk is high.
- Controlled exceptions: allow once, allow for the session, or allow always.
- Manual reporting of suspicious pages or events.
- Optional integration with a web platform for reviewing alerts, verdicts, and investigations.

The extension is intended for defensive use in security, research, and awareness environments. It is not designed for covert surveillance or to monetize user data.
