Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installation downloads and executes a remote binary, then automatically refreshes and installs skills into local AI agents. The agent modifications are implemented by the unavailable downloaded binary. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-15T17:47:04.374Z - **Finished:** 2026-09-15T17:47:59.994Z - **Download time:** 773 ms - **Static scan time:** 89 ms - **AI review time:** 54757 ms - **Total time:** 55620 ms The recorded confidence comes from the underlying analysis.

The agent modifications are implemented by the unavailable downloaded binary. - **Trigger:** npm postinstall during package installation - **Impact:** An install hook can alter local AI-agent capabilities without an explicit user command. - **Evidence paths:** package.json, scripts/postinstall.js, manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-09-15T17:47:59.994Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary bootstrap followed by automatic AI-agent skill installation - **Attack narrative:** When npm installs the package, its postinstall hook downloads a platform-specific executable, verifies it, writes it under bin/, and executes it. Outside CI, the hook then runs +connect --refresh without user interaction. The package states that this operation downloads skills and installs them into detected local AI agents, while the executable that performs those changes is not included for source inspection. - **Rationale:** This is an unconsented install-time chain that fetches and executes opaque remote code and automatically modifies a broad AI-agent control surface. Hash verification does not make the automatic agent installation consensual or inspectable. - **Files touched:** manifest.json, bin/, skills/ - **Network endpoints:** https://lf3-static.bytednsdoc.com, https://github.com/volcengine/ark-cli/releases/download/v1.0.30/ ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs scripts/postinstall.js automatically after installation., The install hook downloads and executes a platform binary from remote URLs., After installation, it automatically invokes the binary to refresh and install skills into detected local AI agents. - **Evidence against:** The downloaded platform binary is checked against a manifest SHA-256 before execution., The inspected JavaScript does not directly collect or transmit environment variables or credentials. ## Affected versions and remediation This report applies to @volcengine/ark-cli@1.0.30. - Avoid installing @volcengine/ark-cli@1.0.30. 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.
