Summary
Malicious code in @lekzsync/baileys (npm)
Details

Malicious package. @lekzsync/baileys is a trojanized fork of the Baileys WhatsApp library (@whiskeysockets/baileys). it silently subscribes every victim (via the injected WhatsApp newsletter/channel FOLLOW on connect) to attacker-controlled WhatsApp channels — hardcoded newsletter JIDs: 120363399602691477@newsletter, 120363421563597486@newsletter. Legitimate Baileys never hardcodes a channel JID or auto-follows on connect; all published versions are malicious.
