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 normal socket construction path starts a delayed task that fetches a publisher-controlled newsletter list and automatically follows every returned ID using the user’s WhatsApp connection. This is an unsolicited account action toward targets chosen by the publisher, so the package is malicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-11-02T02:30:09.113Z - **Finished:** 2026-11-02T02:31:04.191Z - **Download time:** 501 ms - **Static scan time:** 1813 ms - **AI review time:** 52763 ms - **Total time:** 55078 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:** Socket creation triggers unsolicited follows of publisher-selected WhatsApp newsletters. - **Trigger:** When the application creates the package’s normal WhatsApp socket; the package schedules the first fetch 10 seconds later. - **Impact:** The user’s WhatsApp account automatically follows channels chosen through the publisher-controlled list. - **Evidence paths:** lib/Socket/newsletter.js, lib/Socket/username.js, lib/Socket/messages-send.js, lib/Socket/messages-recv.js, lib/Socket/business.js, lib/Socket/communities.js, lib/Socket/index.js, lib/Socket/mex.js - **Review source:** ai\_review - **Reviewed:** 2026-11-02T02:31:04.191Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** It fetches a newsletter ID list from https://push-saurus.yorunime.sbs/idch.json and sends WhatsApp w:mex follow requests for the returned IDs, spaced five seconds apart. - **Attack narrative:** Creating the normal socket builds the newsletter socket, which schedules a fetch to a Base64-hidden external URL after 10 seconds. It reads newsletter IDs from the response and follows each one through WhatsApp’s w:mex protocol without a user request, altering the user’s account toward targets chosen by the publisher. - **Rationale:** The normal socket construction path starts a delayed task that fetches a publisher-controlled newsletter list and automatically follows every returned ID using the user’s WhatsApp connection. This is an unsolicited account action toward targets chosen by the publisher, so the package is malicious. - **Network endpoints:** https://push-saurus.yorunime.sbs/idch.json, s.whatsapp.net ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** Creating the normal socket reaches makeNewsletterSocket through the package’s socket constructor chain., makeNewsletterSocket schedules a fetch to a Base64-encoded URL, then follows newsletter IDs supplied by its response., The follow requests use WhatsApp’s w:mex protocol, so the automatic action affects the user’s WhatsApp account. - **Evidence against:** The preinstall hook only checks the Node.js major version and exits when it is below 20., No source evidence shows credentials being sent to the external list host. ## Affected versions and remediation This report applies to sauruspro-bail@5.0.0. - Avoid installing sauruspro-bail@5.0.0. 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.
