Creating a normal WhatsApp socket then schedules a hidden remote-list fetch and authenticated queries. - **Trigger:** npm postinstall; later creation of a WhatsApp socket - **Impact:** Consumer imports of @whiskeysockets/baileys are redirected; authenticated WhatsApp activity is induced from an attacker-controlled list. - **Evidence paths:** package.json, scripts/postinstall.js, lib/Socket/newsletter.js, lib/Socket/messages-send.js - **Review source:** ai\_review - **Reviewed:** 2026-07-22T22:37:53.260Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** dependency namespace hijack plus covert remote-driven WhatsApp queries - **Attack narrative:** At install, the package removes the consumer's @whiskeysockets/baileys directory and writes a replacement manifest pointing imports to megan-baileys. When its normal socket construction path reaches makeNewsletterSocket, it waits 90 seconds, decodes and fetches a remote JID list, then sends WhatsApp MEX queries for every returned JID using the consumer's authenticated socket. - **Rationale:** The lifecycle script silently hijacks another package's namespace, and runtime code performs undisclosed remote-controlled activity through user credentials. These are concrete malicious behaviors, not required Baileys compatibility operations. - **Files touched:** scripts/postinstall.js, node\_modules/@whiskeysockets/baileys, node\_modules/@whiskeysockets/baileys/package.json, lib/Socket/newsletter.js - **Network endpoints:** https://files.gifted.co.ke/file/chJids.json ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs postinstall., scripts/postinstall.js deletes and replaces consumer node\_modules/@whiskeysockets/baileys., Replacement manifest redirects @whiskeysockets/baileys imports to this package., lib/Socket/newsletter.js covertly fetches a Base64-hidden remote JID list and queries it through the user's authenticated WhatsApp socket. - **Evidence against:** FFmpeg execution and dynamic audio decoder import in lib/Utils/messages-media.js are media-processing features., Other observed network calls support WhatsApp/media/version functionality. ## Public findings ### 1.
