Third-party coding agents can receive Ark skills and related config during package install, without the user running arkcli +connect. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.0.23 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. npm postinstall downloads a native arkcli binary and then non-interactively runs +connect --refresh, which auto-detects local agents and installs skills into them. README names Claude Code, OpenCode, and Codex as targets, so this is install-time mutation of foreign agent control surfaces without an explicit user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 90.0% - **Started:** 2026-09-17T07:28:31.511Z - **Finished:** 2026-09-17T07:32:16.737Z - **Download time:** 780 ms - **Static scan time:** 104 ms - **AI review time:** 224340 ms - **Total time:** 225226 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:** npm postinstall downloads a native arkcli binary and then non-interactively runs +connect --refresh, which auto-detects local agents and installs skills into them. README names Claude Code, OpenCode, and Codex as targets, so this is install-time mutation of foreign agent control surfaces without an explicit user command. - **Trigger:** npm install of @volcengine/ark-cli, which runs the postinstall script unless CI or ARKCLI\_SKIP\_POSTINSTALL=1. - **Impact:** Third-party coding agents can receive Ark skills and related config during package install, without the user running arkcli +connect. - **Evidence paths:** package.json, scripts/postinstall.js, manifest.json, README.md - **Review source:** ai\_review - **Reviewed:** 2026-09-17T07:32:16.737Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** unconsented postinstall agent skill injection via a downloaded binary - **Attack narrative:** On npm install, postinstall fetches a native arkcli binary from the ByteDance CDN, verifies a baked sha256, and executes it. Except in CI, it then runs arkcli +connect --refresh even without a TTY. Package comments say that command auto-detects agents and installs skills into all of them; the README names Claude Code, OpenCode, and Codex. Install docs present +connect as a later explicit step, so the lifecycle run is not consented. Global installs also enroll silent automatic updates on new machines. Skill install logic lives in the opaque Go binary, but the JavaScript hook itself is an unconsented write into foreign agent control surfaces. - **Rationale:** The postinstall hook downloads a native binary and non-interactively runs arkcli +connect --refresh to auto-detect local agents and install skills into them. That is unconsented install-time mutation of foreign and broad AI-agent control surfaces, so the package should be blocked. - **Files touched:** manifest.json, bin/arkcli-${platform}-${arch}, ~/.arkcli, /dev/tty - **Network endpoints:** https://lf3-static.bytednsdoc.com, https://github.com/volcengine/ark-cli ### Review decision - **Verdict:** Malicious - **Confidence:** 90.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** package.json runs scripts/postinstall.js automatically on npm postinstall., postinstall downloads a platform binary from the vendor CDN into bin/, chmod's it, and executes it., After a non-CI install it always runs the binary as arkcli +connect --refresh, including when there is no TTY., Comments say +connect is non-interactive, auto-detects agents, and installs skills into all of them., README says those skills are given to Claude Code, OpenCode, Codex, and other local agents., Global installs enroll silent automatic updates by default on new machines. - **Evidence against:** Binary and skill URLs are ByteDance CDN and GitHub releases with sha256 pins in manifest.json., CI variables and ARKCLI\_SKIP\_POSTINSTALL=1 skip the hook., Inspectable JavaScript does not steal environment secrets or use eval., Scoped @volcengine name, Apache-2.0 license, and github.com/volcengine/ark-cli metadata., +connect failures are warnings and do not fail the npm install. ## Affected versions and remediation This report applies to @volcengine/ark-cli@1.0.23. - Avoid installing @volcengine/ark-cli@1.0.23. 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.
