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. An automatically invoked, obfuscated browser routine fetches IP and location data and uses WhatsApp messaging functions. A confirmed attack is not established because its destinations and effective conditions remain unresolved. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 79.0% - **Started:** 2026-09-30T16:19:14.672Z - **Finished:** 2026-09-30T16:22:24.218Z - **Download time:** 520 ms - **Static scan time:** 1926 ms - **AI review time:** 187099 ms - **Total time:** 189546 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:** An automatically invoked, obfuscated browser routine fetches IP and location data and uses WhatsApp messaging functions. A confirmed attack is not established because its destinations and effective conditions remain unresolved. - **Trigger:** Runtime injection of the initialization patch during WhatsApp browser setup. - **Impact:** Potential disclosure of IP and approximate location; attacker receipt is not established. - **Evidence paths:** dist/transport/assets/init\_patch.js, dist/index.cjs - **Review source:** ai\_review - **Reviewed:** 2026-09-30T16:22:24.218Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The patch invokes notifyHost, fetches IP-related data, and conditionally passes location and IP information to messaging functions. - **Rationale:** The automatically invoked IP and location notification behavior leaves a concrete privacy risk unresolved. The inspected source does not establish attacker-directed exfiltration or another block-eligible attack. ### Review decision - **Verdict:** Suspicious - **Confidence:** 79.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** High - **Evidence for warning:** The initialization patch fetches IP data through obscured endpoints., The same routine passes location fields and the fetched IP to WhatsApp messaging functions; destination and branch conditions remain obscured., The initialization patch automatically calls its notification routine., The active CommonJS entrypoint evaluates the initialization patch in the browser., package.json contains no registry installation lifecycle hook. - **Evidence against:** The package implements WhatsApp browser automation, including runtime patches and licensing., The notification recipient appears derived from the current account identity, so delivery to an attacker is not established. ## Affected versions and remediation This report applies to @open-wa/core@5.4.0. - Review the evidence and your use of @open-wa/core@5.4.0 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.
