Malicious code in @ubedsockets/baileys (npm)
Details
**Severity:** Critical **Affected versions:** `> 0` Malicious package. `@ubedsockets/baileys` is a trojanized fork of the Baileys WhatsApp library (@whiskeysockets/baileys). On connection it issues an authenticated `w:mex` newsletter FOLLOW mutation (query_id 7871414976211147) that silently subscribes every victim to attacker-controlled WhatsApp channels — hardcoded newsletter JIDs: 120363410154606795@newsletter, 120363423295236859@newsletter. Legitimate Baileys never hardcodes a channel JID or auto-follows on connect; all published versions are malicious. Detected by wormsign static analysis of the injected channel-subscription code. --- Credit: [OpenSSF](https://github.com/ossf/malicious-packages) ([source](https://github.com/ossf/malicious-packages/blob/6282ccd01cbcaeab639c2217d5515a4869847d8b/osv/malicious/npm/@ubedsockets/baileys/MAL-2026-18600.json)) **References:** - https://github.com/ossf/malicious-packages/blob/6282ccd01cbcaeab639c2217d5515a4869847d8b/osv/malicious/npm/@ubedsockets/baileys/MAL-2026-18600.json - https://wormsign.io/portfolio/@ubedsockets/baileys - https://github.com/advisories/GHSA-qwpw-cwrq-333j
