Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The login trace is transmitted automatically as part of a user-started login, and the packaged README does not clearly disclose that telemetry. The behavior is limited to the package’s own API and login purpose, so this warrants a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-10-29T18:37:58.153Z - **Finished:** 2026-10-29T18:38:56.538Z - **Download time:** 260 ms - **Static scan time:** 219 ms - **AI review time:** 57906 ms - **Total time:** 58385 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Undisclosed runtime login telemetry is sent to Keyhand’s API during login runs. - **Trigger:** A user starts a login through the SDK or CLI test command. - **Impact:** Keyhand receives login activity metadata without a clear telemetry disclosure in the packaged README; session state is also transmitted as part of the product’s login and session reuse behavior. - **Evidence paths:** dist/keyhand-CHqQyyQf.mjs, dist/src-DniIPvR8.mjs, dist/index.mjs - **Review source:** ai\_review - **Reviewed:** 2026-10-29T18:38:56.538Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The SDK builds a trace containing login host and normalized path information, then includes it in the lease release request. Successful runs may also send browser session state. - **Rationale:** The login trace is transmitted automatically as part of a user-started login, and the packaged README does not clearly disclose that telemetry. The behavior is limited to the package’s own API and login purpose, so this warrants a warning rather than a block. - **Network endpoints:** https://keyhand-api.kumarbharath63.workers.dev, User-configured KEYHAND\_API\_URL ### Review decision - **Verdict:** Suspicious - **Confidence:** 90.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The SDK records login structure in a trace that its source labels telemetry., The trace can include the identity host and normalized page path; form structure is fingerprinted., At the end of a login run, the release body includes the trace and may include browser session state, then posts to the API., The CLI defaults to the Keyhand API host, with a user-configurable override., The package has no install lifecycle scripts; its declared scripts are build and typecheck. - **Evidence against:** The README describes the package as managing browser-agent identities and secrets and running login checks., Trace transmission occurs as part of a login run initiated by the user, rather than on installation or import., The CLI reads the Keyhand API key through its sign-in flow, and the API URL can be configured. ## Affected versions and remediation This report applies to keyhand@0.1.0-pre.4. - Review the evidence and your use of keyhand@0.1.0-pre.4 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
