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 callable socket method transmits a supplied phone number to an unrelated external service. This is a concrete runtime data-exfiltration path. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-14T12:56:50.534Z - **Finished:** 2026-09-14T12:57:46.865Z - **Download time:** 509 ms - **Static scan time:** 1550 ms - **AI review time:** 54271 ms - **Total time:** 56331 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:** A callable socket method transmits a supplied phone number to an unrelated external service. This is a concrete runtime data-exfiltration path. - **Trigger:** A consumer calls the socket object's checkBan(number) method. - **Impact:** Phone numbers supplied by consumers are disclosed to the external host. - **Evidence paths:** lib/Socket/socket.js - **Review source:** ai\_review - **Reviewed:** 2026-09-14T12:57:46.865Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Third-party HTTP request containing a phone number. - **Attack narrative:** The socket factory exposes checkBan. When called, it normalizes the provided phone number and places it in a GET request to xzc-corporation.biz.id, a host unrelated to the WhatsApp service APIs used elsewhere. The request also carries an offensive custom header. This discloses user-supplied phone numbers to a third party without a package-aligned service endpoint. - **Rationale:** The package contains an exported runtime path that exfiltrates supplied phone numbers to an unrelated host with a deliberately abusive header. Although not automatic, this is concrete malicious data collection behavior. - **Network endpoints:** xzc-corporation.biz.id ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The exported checkBan method sends the supplied phone number to an unrelated third-party host., The request includes an offensive custom header, indicating deliberate nonstandard behavior., The method is returned by the socket factory and is callable by package consumers. - **Evidence against:** The transfer is triggered only when a consumer calls checkBan; it is not install-time or import-time., The preinstall hook only checks the Node.js major version and exits for versions below 20. ## Affected versions and remediation This report applies to xzvbails@0.0.1. - Avoid installing xzvbails@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.
