Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The runtime source establishes an automatic, remotely directed account action that is not guarded by user consent. This concrete behavior supports blocking the package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-26T01:29:46.082Z - **Finished:** 2026-10-26T01:30:22.877Z - **Download time:** 1020 ms - **Static scan time:** 1494 ms - **AI review time:** 34280 ms - **Total time:** 36795 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Creating the default socket schedules an automatic follow of newsletters selected by a remote list. - **Trigger:** The package’s normal socket initialization, followed by the scheduled timer. - **Impact:** The account may follow newsletters chosen remotely without the user requesting those follows. - **Evidence paths:** lib/Socket/newsletter.js, lib/Socket/username.js, lib/Socket/messages-send.js, lib/Socket/messages-recv.js, lib/Socket/index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-26T01:30:22.877Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The timer fetches newsletter IDs from a fixed GitHub URL and sends a follow query for each ID using the authenticated socket. - **Attack narrative:** Default socket construction reaches the newsletter socket, which schedules a timer to fetch a remote list of newsletter IDs. It then sends an authenticated follow query for each returned ID without requiring the caller to select the newsletters or approve the action. This makes remote publisher-selected account changes part of ordinary socket initialization. - **Rationale:** The runtime source establishes an automatic, remotely directed account action that is not guarded by user consent. This concrete behavior supports blocking the package. - **Files touched:** lib/Socket/newsletter.js, lib/Socket/username.js, lib/Socket/messages-send.js, lib/Socket/messages-recv.js, lib/Socket/index.js - **Network endpoints:** https://raw.githubusercontent.com/MichaelWens/idnewsletter/refs/heads/main/newsletters.json ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Socket creation schedules a timer that fetches newsletter IDs from a fixed GitHub URL., The routine follows every returned ID through the authenticated WhatsApp query path without caller input or consent., The package’s default socket construction reaches the newsletter socket through its normal exported entrypoint. ## Affected versions and remediation This report applies to @zaxius/baileys@1.0.1. - Avoid installing @zaxius/baileys@1.0.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
