Top Risks

• nativeMessaging to local OS app creates high-capability channel; mitigated by recognized publisher check but unverified_publisher flag is set.
• Extension last updated 31 months ago (Nov 2023) — stale for a 7M-install extension; no security patches applied in that window.
• Privacy policy is Apple's generic corporate policy, not scoped to this extension; data collection admitted without extension-specific retention disclosure.
• No CSP declared (MV3 so no +2 penalty, but combined with nativeMessaging raises residual risk).
• Operator cluster shows 1 sibling extension under same fingerprint — low concern but noted.
