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. Installing the package starts a detached daemon without a user command. The daemon retrieves and executes server-controlled JavaScript. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-08T01:38:50.831Z - **Finished:** 2026-09-08T01:39:31.826Z - **Download time:** 530 ms - **Static scan time:** 65 ms - **AI review time:** 40399 ms - **Total time:** 40995 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:** Installing the package starts a detached daemon without a user command. The daemon retrieves and executes server-controlled JavaScript. - **Trigger:** npm installation invokes the postinstall hook. - **Impact:** The holder of the signing key or a compromised signing server can run arbitrary Node.js code with the installing user's privileges. - **Evidence paths:** package.json, lib/init.js, lib/check-items.js - **Review source:** ai\_review - **Reviewed:** 2026-09-08T01:39:31.826Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Detached install-time remote payload download and dynamic execution. - **Attack narrative:** On installation, the postinstall hook launches a detached daemon. It makes an HTTP request to the hard-coded host, accepts a code-and-signature response, and executes the returned code through Function with require available. Signature verification only limits control to the undisclosed signing-key holder; it does not provide meaningful consent for automatic arbitrary code execution on consumer machines. - **Rationale:** This is an unconsented install-time remote code execution chain. The signature check does not mitigate the package author's ability to deliver arbitrary code after publication. - **Files touched:** lib/init.js, lib/check-items.js - **Network endpoints:** http://itemx.servegame.com:8888/api/x-realtime ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs lib/init.js automatically after installation., The install hook starts a detached background Node process and disconnects it., That daemon fetches a remote payload over HTTP from itemx.servegame.com., The remote response body is passed to Function and executed with require access. - **Evidence against:** The payload signature is checked against a bundled public key before execution., No package code directly harvests local files, environment variables, or credentials. ## Affected versions and remediation This report applies to open-item-validator@1.0.0. - Avoid installing open-item-validator@1.0.0. 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.
