AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. The package’s preinstall and postinstall hooks perform automatic disclosure of identifying installation data to a fixed external collector without installer consent. This meets the installation beacon policy for blocking. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-10-27T09:48:51.362Z - **Finished:** 2026-10-27T09:49:28.060Z - **Download time:** 506 ms - **Static scan time:** 14 ms - **AI review time:** 36178 ms - **Total time:** 36698 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:** Install-time hooks disclose installer and environment identifiers to a fixed external host. This is an automatic installation beacon with no consent guard in the hooks. - **Trigger:** npm runs the package’s preinstall or postinstall hook. - **Impact:** The recipient learns identifying information about the installer and installation environment. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-10-27T09:49:28.060Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Each hook sends the user name, hostname, and working directory in an HTTP request to 38.242.235.206. - **Attack narrative:** During installation, either lifecycle hook automatically sends the installer’s user name, hostname, and working directory to a fixed external IP over HTTP. The source shows no affirmative consent check for this disclosure. - **Rationale:** The package’s preinstall and postinstall hooks perform automatic disclosure of identifying installation data to a fixed external collector without installer consent. This meets the installation beacon policy for blocking. - **Files touched:** package.json - **Network endpoints:** http://38.242.235.206/depconf/mui-wrapper-x-date-pickers/preinstall, http://38.242.235.206/depconf/mui-wrapper-x-date-pickers/postinstall ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json defines preinstall and postinstall hooks that send the installer’s user name, hostname, and working directory to a fixed IP address over HTTP without a consent guard. ## Affected versions and remediation This report applies to mui-wrapper-x-date-pickers@10.0.0. - Avoid installing mui-wrapper-x-date-pickers@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.
