Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. No install-time or import-time attack was identified. Network and crypto code implement a user-invoked WhatsApp client against WhatsApp, Apple, and Google services. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-30T10:34:09.173Z - **Finished:** 2026-09-30T10:35:08.617Z - **Download time:** 503 ms - **Static scan time:** 4327 ms - **AI review time:** 54606 ms - **Total time:** 59444 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:** No install-time or import-time attack was identified. Network and crypto code implement a user-invoked WhatsApp client against WhatsApp, Apple, and Google services. - **Trigger:** A person runs the wa CLI or calls the library API. - **Impact:** No unsolicited credential theft, remote payload execution, persistence, or foreign agent-config mutation was found. - **Review source:** ai\_review - **Reviewed:** 2026-09-30T10:35:08.617Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Registration, push, and messaging code talks to the services named by the library and stores session files the caller selects. - **Rationale:** The package is an unofficial WhatsApp client whose hooks, token tables, APNs activation, APK token derivation, and CLI all match that product and run only when the user invokes them. Static inspection found no lifecycle self-install, hidden exfiltration, or unconsented agent-control writes. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Low - **Evidence for AI clean decision:** package.json exposes a user CLI bin and only test scripts, with no preinstall, install, or postinstall hook., lib/tokens.js is a WhatsApp protocol token dictionary that includes the host s.whatsapp.net., lib/apns.js requests an APNs device certificate from Apple's albert activation URL as part of WhatsApp push registration., lib/AndroidApk.js derives the Android registration token with PBKDF2-HMAC-SHA1 over APK material., cli.js is an explicit Node entrypoint that loads the WhatsApp client only when the user runs it. - **Evidence against:** Session writes stay under the user session directory or a local config file, and the only child process is ffmpeg for media thumbnails., Dependencies do not include this package name, and there is no eval, vm, or dynamic payload fetch. ## Affected versions and remediation This report applies to whalibmob@5.33.2. - Avoid installing whalibmob@5.33.2. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
