This rule detects command-line activity that searches for sensitive information within browser extension storage, specifically targeting data related to cryptocurrency wallets, password managers, or authenticator applications. It looks for commands executed by common interpreters like cmd, PowerShell, or Python that include keywords associated with extensions and sensitive data like 'wallet', 'metamask', 'password', 'authenticator', '2fa', or 'crypto'. The rule is designed to provide causality and actor information for investigation.
