AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The install hooks perform automatic disclosure of identifying installation data to a fixed external recipient without installer consent. This supports blocking as install-hook abuse. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-27T09:48:28.360Z - **Finished:** 2026-10-27T09:48:50.036Z - **Download time:** 516 ms - **Static scan time:** 16 ms - **AI review time:** 21143 ms - **Total time:** 21676 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:** Both install hooks send identifying environment details to a fixed external address. - **Trigger:** Installing the package runs its preinstall and postinstall hooks. - **Impact:** The recipient can identify the installer and installation environment. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-10-27T09:48:50.036Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hooks send the user name, machine hostname, and current working directory in HTTP GET query parameters without a consent check. - **Attack narrative:** During installation, the package sends the user name, hostname, and working directory to a fixed external address in both preinstall and postinstall requests. The hooks contain no consent check. - **Rationale:** The install hooks perform automatic disclosure of identifying installation data to a fixed external recipient without installer consent. This supports blocking as install-hook abuse. - **Network endpoints:** http://38.242.235.206/depconf/mw-communication-client/preinstall, http://38.242.235.206/depconf/mw-communication-client/postinstall ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The preinstall hook makes an HTTP GET to a fixed address, sending the user name, hostname, and working directory., The postinstall hook repeats that disclosure automatically during installation, with no consent check. ## Affected versions and remediation This report applies to mw-communication-client@10.0.0. - Avoid installing mw-communication-client@10.0.0. 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.
