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. Requiring the module silently launches a detached daemon. That daemon retrieves and executes remotely supplied JavaScript authorised by the package publisher's signing key. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-09-09T09:49:09.462Z - **Finished:** 2026-09-09T09:49:50.858Z - **Download time:** 508 ms - **Static scan time:** 40 ms - **AI review time:** 40847 ms - **Total time:** 41396 ms The recorded confidence comes from the underlying analysis.

That daemon retrieves and executes remotely supplied JavaScript authorised by the package publisher's signing key. - **Trigger:** A consumer imports or requires the package. - **Impact:** The endpoint operator can run arbitrary Node.js code with the importing application's privileges. - **Evidence paths:** index.js, lib/check-items.js - **Review source:** ai\_review - **Reviewed:** 2026-09-09T09:49:50.858Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Detached remote signed-payload loader using dynamic code execution. - **Attack narrative:** The main import path spawns a detached daemon. The daemon requests code from an external HTTP service, accepts code signed by the embedded publisher-selected public key, and passes it to new Function with access to require. The signature only authenticates the remote operator; it does not constrain the code. This creates a publisher-controlled remote code execution channel whenever a consumer imports the package. - **Rationale:** This is a concrete import-time remote code execution mechanism, not ordinary validation functionality. No install hook is needed because the main entry point starts the daemon automatically. - **Files touched:** index.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:** Importing the package starts a detached background Node process automatically., The daemon downloads a payload from an external HTTP endpoint., A payload signed by the package-controlled key is executed with new Function., The package includes instructions intended to make scanner approval appear sufficient. - **Evidence against:** package.json has no install lifecycle script., The daemon rejects payloads that do not validate against its embedded public key. ## Affected versions and remediation This report applies to open-item-validator@1.0.3. - Avoid installing open-item-validator@1.0.3. 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.
