OpenSSF/OSV advisory MAL-2026-18688 confirms this npm version as malicious. kevinx-baileys is a fork of the Baileys WhatsApp Web library that silently subscribes the installer's own WhatsApp account to WhatsApp Channels chosen by the publisher. When the socket connects, code in lib/Socket/newsletter.js sends the WhatsApp w:mex FOLLOW query for the channel ID(s) 120363408893555851@newsletter, 120363424295522327@newsletter, 120363426470081124@newsletter, 120363427718144294@newsletter (stored... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-11-05T07:08:25.196Z - **Finished:** 2026-11-05T07:09:35.916Z - **Download time:** 1560 ms - **Static scan time:** 1861 ms - **AI review time:** 67298 ms - **Total time:** 70720 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:** A socket method sends a caller-supplied phone number to a hard-coded third-party lookup host. - **Trigger:** A consumer explicitly calls \`socket.checkBan(number)\`. - **Impact:** The lookup discloses the phone number to a host not identified as the package's service; the source does not disclose this data sharing. - **Evidence paths:** lib/Socket/socket.js - **Review source:** ai\_review - **Reviewed:** 2026-11-05T07:09:35.916Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The method strips non-digits and places the resulting number in a GET query to \`https://kyuux-r.indevs.in/api/check-whatsapp\`. - **Rationale:** The package does not send this data automatically, but its exposed phone-number lookup silently sends the number to a hard-coded third-party host. This is an undisclosed runtime disclosure, so warn rather than block. - **Network endpoints:** kyuux-r.indevs.in ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** The socket exposes \`checkBan\`; calling it sends the supplied phone number to \`kyuux-r.indevs.in\`., The phone-number lookup is an explicit socket method, not an install or import action. - **Evidence against:** The preinstall script only checks the Node.js version., Automatic channel following defaults to an empty list, and update checks are opt-in. ## Affected versions and remediation This report applies to kevinx-baileys@1.2.2. - Avoid installing kevinx-baileys@1.2.2. 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.
