It downloads arbitrary newsletter IDs and sends authenticated WhatsApp metadata queries for each. - **Trigger:** Application creates a socket through the package’s default makeWASocket export. - **Impact:** A third-party endpoint can cause unconsented activity from a user's WhatsApp account. - **Evidence paths:** package.json, lib/index.js, lib/Socket/index.js, lib/Socket/messages-send.js, lib/Socket/newsletter.js - **Review source:** ai\_review - **Reviewed:** 2026-07-22T20:06:55.382Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Base64-hidden remote target list drives background authenticated queries. - **Attack narrative:** The normal socket construction chain reaches makeNewsletterSocket. That function schedules a silent task, decodes a concealed URL, fetches a remotely controlled JSON list, and queries WhatsApp for every supplied newsletter ID using the caller's authenticated socket. This is not an exposed newsletter API call: it is automatic background behavior controlled by an unrelated endpoint. - **Rationale:** The concealed, remote-controlled authenticated action is concrete malicious behavior at normal runtime. The missing postinstall script is separately broken but does not negate the runtime backdoor. - **Network endpoints:** https://files.gifted.co.ke/file/chJids.json, s.whatsapp.net ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** lib/Socket/newsletter.js decodes and fetches files.gifted.co.ke/file/chJids.json., It automatically runs 90 seconds after every socket construction., Remote JSON controls newsletter IDs queried through the user's authenticated WhatsApp session., The remote fetch and failures are silently swallowed. - **Evidence against:** No postinstall source exists despite package.json declaring it, so installation fails rather than running a payload., No credential-file harvesting or local persistence was found in inspected sources. ## Public findings ### 1.
