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. On installation, the package fetches and executes an opaque native binary. It then automatically asks that binary to refresh and install skills into local AI agents. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-15T21:41:24.958Z - **Finished:** 2026-09-15T21:42:20.091Z - **Download time:** 765 ms - **Static scan time:** 88 ms - **AI review time:** 54279 ms - **Total time:** 55133 ms The recorded confidence comes from the underlying analysis.

It then automatically asks that binary to refresh and install skills into local AI agents. - **Trigger:** npm postinstall - **Impact:** Unconsented install-time mutation of AI-agent control surfaces through code absent from the package snapshot. - **Evidence paths:** package.json, scripts/postinstall.js, manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-09-15T21:42:20.091Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary bootstrap followed by automatic agent skill installation - **Attack narrative:** Installing the package runs postinstall. The hook downloads a platform-specific executable from manifest-controlled URLs, verifies it, marks it executable, and runs it. It then invokes +connect --refresh without a user command; package comments state this detects agents and installs skills. Because the binary and skill logic are not included in the package, the automatic cross-agent mutation is opaque to static review. - **Rationale:** This is an automatic lifecycle chain that executes a remotely obtained opaque binary and broadly installs AI-agent skills. The embedded hash does not make the unreviewable, unconsented agent-control mutation safe. - **Files touched:** bin/arkcli-${platform}-${arch}${ext}, skills/ - **Network endpoints:** https://lf3-static.bytednsdoc.com, https://github.com/volcengine/ark-cli/releases/download/v1.0.29 ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package runs a postinstall hook automatically., Postinstall downloads a platform binary, saves it as executable, and invokes it., The install hook automatically runs the downloaded binary with +connect --refresh to install skills into detected agents., The shipped source does not contain the downloaded binary or its skill-installation logic, so those install-time effects cannot be audited from this package., The manifest fetches a skills archive from a CDN, with a GitHub archive fallback. - **Evidence against:** Downloaded binaries are checked against SHA-256 values embedded in manifest.json., The visible JavaScript does not harvest credentials or exfiltrate local files. ## Affected versions and remediation This report applies to @volcengine/ark-cli@1.0.29. - Avoid installing @volcengine/ark-cli@1.0.29. 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.
