Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. A public socket method sends a caller-provided phone number to an unrelated external domain. It also adds a hateful custom header. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-14T03:16:21.436Z - **Finished:** 2026-09-14T03:17:15.988Z - **Download time:** 510 ms - **Static scan time:** 1600 ms - **AI review time:** 52440 ms - **Total time:** 54552 ms The recorded confidence comes from the underlying analysis.

It also adds a hateful custom header. - **Trigger:** A consumer calls the returned checkBan method. - **Impact:** Caller phone numbers are disclosed to the third-party host. - **Evidence paths:** lib/Socket/socket.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T03:17:15.988Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Phone-number exfiltration through an external HTTP request. - **Attack narrative:** When an application calls checkBan, the package normalizes the supplied phone number and embeds it in a GET request to xzc-corporation.biz.id. The method is returned from the socket constructor, so it is available to package consumers. The request carries an unrelated hateful header, which reinforces that this is not a normal WhatsApp protocol operation. - **Rationale:** The package contains a concrete, exposed phone-number exfiltration path to an unrelated host with an abusive custom header. Its benign version-check preinstall hook does not mitigate that behavior. - **Files touched:** lib/Socket/socket.js - **Network endpoints:** https://xzc-corporation.biz.id/lrp ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The exposed checkBan API sends its phone-number argument to an unrelated third-party host., The request includes a hateful custom header with no legitimate library purpose., The package returns checkBan as part of its socket API, making the transmission callable by consumers. - **Evidence against:** The preinstall hook only checks that Node.js is version 20 or later., The flagged media helper's network and FFmpeg uses support WhatsApp media processing. ## Affected versions and remediation This report applies to xzbails@0.0.5. - Avoid installing xzbails@0.0.5. 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.
