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. Installing the package automatically downloads and executes an opaque native binary. That binary is invoked to refresh and install skills into automatically detected agents. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-13T05:59:45.899Z - **Finished:** 2026-09-13T06:00:23.083Z - **Download time:** 762 ms - **Static scan time:** 116 ms - **AI review time:** 36305 ms - **Total time:** 37184 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 automatically downloads and executes an opaque native binary. That binary is invoked to refresh and install skills into automatically detected agents. - **Trigger:** npm postinstall during package installation - **Impact:** An unconsented install lifecycle can modify broad AI-agent control surfaces through code not present in the package snapshot. - **Evidence paths:** package.json, scripts/postinstall.js, manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-09-13T06:00:23.083Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** downloaded binary execution followed by automatic agent skill installation - **Attack narrative:** The postinstall hook fetches a platform-specific native executable from manifest-controlled URLs, verifies its package-provided hash, saves it under bin/, and executes it. It then invokes +connect --refresh non-interactively; source comments state this downloads skills and installs them into automatically detected agents. This is an unconsented lifecycle mutation of a broad AI-agent control surface using opaque downloaded code. - **Rationale:** The package performs automatic install-time network retrieval and execution of an opaque binary, then automatically installs agent skills. This creates a concrete unconsented AI-agent control-surface attack path. - **Files touched:** manifest.json, bin/arkcli-${platform}-${arch}${ext}, skills/ - **Network endpoints:** https://lf3-static.bytednsdoc.com, https://github.com/volcengine/ark-cli/releases ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** An automatic postinstall hook runs the installer., The installer downloads a platform binary, verifies it, and writes it into the package., Postinstall executes that downloaded binary with an automatic agent-refresh command., The downloaded opaque binary can install skills into detected agents during dependency installation. - **Evidence against:** The downloaded binary is checked against a SHA-256 value embedded in the package manifest., The JavaScript installer contains no direct credential collection or direct data exfiltration. ## Affected versions and remediation This report applies to @volcengine/ark-cli@1.0.26. - Avoid installing @volcengine/ark-cli@1.0.26. 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.
