## From the sources

Malicious package. `sauruspro-bail` 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: 120363418964199743@newsletter, 120363429190136593@newsletter. Legitimate Baileys never hardcodes a channel JID or auto-follows on connect; all published versions are malicious.
