Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. LPM treats this as warn-only first-party agent extension lifecycle risk. Installing the package downloads and executes an opaque platform binary. Outside CI, that binary is automatically asked to refresh and install Ark skills into local agents. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 87.0% - **Started:** 2026-09-16T01:31:36.934Z - **Finished:** 2026-09-16T01:32:38.548Z - **Download time:** 1023 ms - **Static scan time:** 89 ms - **AI review time:** 60501 ms - **Total time:** 61614 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 downloads and executes an opaque platform binary. Outside CI, that binary is automatically asked to refresh and install Ark skills into local agents. - **Trigger:** npm postinstall during package installation - **Impact:** Local AI-agent configuration may be changed without an explicit CLI command; the downloaded binary's behavior is not inspectable in this package. - **Evidence paths:** package.json, scripts/postinstall.js, manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-09-16T01:32:38.548Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary bootstrap followed by automatic agent skill setup - **Rationale:** No source evidence establishes credential theft, destructive behavior, or a malicious payload. However, automatic execution of a remotely supplied binary to configure local agents warrants a warning. - **Files touched:** scripts/postinstall.js, manifest.json, bin/ - **Network endpoints:** lf3-static.bytednsdoc.com, github.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 87.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for warning:** The package runs a postinstall script during npm installation., The postinstall script downloads a platform binary, verifies its SHA-256 digest, and executes it., The install hook automatically invokes the downloaded binary with +connect --refresh, which is intended to install skills into detected local agents. - **Evidence against:** The JavaScript downloader checks each downloaded binary against a manifest-pinned SHA-256 digest., The inspected JavaScript contains no credential harvesting or outbound secret submission., The remote binary and skills are package-aligned, but their behavior cannot be verified from this source snapshot. ## Affected versions and remediation This report applies to @volcengine/ark-cli@1.0.28. - Review the evidence and your use of @volcengine/ark-cli@1.0.28 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
