That constructor unconditionally schedules a WhatsApp follow request for a fixed newsletter ID after 90 seconds. The request uses the package's WhatsApp query path and has no caller opt-in or target selection guard, so it can change the consumer's account by following a publisher-selected newsletter. - **Rationale:** Source inspection confirms a reachable, automatic account follow action for a fixed target during ordinary socket construction. This unrequested account mutation supports blocking the package. - **Files touched:** lib/index.js, lib/Socket/index.js, lib/Socket/communities.js, lib/Socket/business.js, lib/Socket/messages-recv.js, lib/Socket/messages-send.js, lib/Socket/username.js, lib/Signal/Group/Protocols.js, lib/Socket/mex.js, lib/Types/Mex.js ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The main export exposes a socket constructor that builds the community socket layer., The constructor chain reaches the newsletter socket through the community, business, receive, send, and username layers., Newsletter socket construction unconditionally schedules a follow request for a fixed newsletter ID after 90 seconds., The request uses the WhatsApp query path and the FOLLOW protocol action. - **Evidence against:** The preinstall hook only checks the Node.js major version and exits on unsupported versions., The scheduled follow request suppresses errors, but has no caller opt-in or target selection guard. ## Affected versions and remediation This report applies to @lekzox/baileys@0.0.1. - Avoid installing @lekzox/baileys@0.0.1. 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.
