Foreign local AI-agent control surfaces may be modified without an explicit user command. - **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:** 1.0.27 - **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. Installing the package downloads and executes an opaque external binary. The lifecycle then non-interactively refreshes and installs skills into detected local AI agents. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 98.0% - **Started:** 2026-09-12T00:35:22.209Z - **Finished:** 2026-09-12T00:36:23.595Z - **Download time:** 758 ms - **Static scan time:** 104 ms - **AI review time:** 60523 ms - **Total time:** 61386 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 external binary. The lifecycle then non-interactively refreshes and installs skills into detected local AI agents. - **Trigger:** npm postinstall outside CI - **Impact:** Foreign local AI-agent control surfaces may be modified without an explicit user command. - **Evidence paths:** package.json, scripts/postinstall.js, manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-09-12T00:36:23.595Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary bootstrap followed by automatic AI-agent skill installation - **Attack narrative:** The postinstall hook obtains a platform binary from manifest-controlled URLs, verifies its digest, and executes it. Unless it detects CI, it automatically invokes the binary with +connect --refresh. The package source says this action detects agents and installs skills into all of them, while the implementation is opaque because the binary is fetched at install time. This is an unconsented install-time mutation path for local AI-agent control surfaces. - **Rationale:** This is a concrete, automatic postinstall path that executes a remote binary and installs skills into detected AI agents without an explicit user command. Hash verification does not make the unconsented broad agent mutation safe. - **Files touched:** manifest.json, bin/, scripts/postinstall.js - **Network endpoints:** lf3-static.bytednsdoc.com, github.com ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package runs a postinstall script automatically., Postinstall downloads an external platform binary into bin/ and executes it., Outside CI, postinstall non-interactively runs +connect --refresh; source states it detects agents and installs skills into all of them., The manifest identifies an externally hosted skills archive. - **Evidence against:** The downloaded binary is checked against a manifest SHA-256 value., The script skips its agent action in common CI environments and offers an environment-variable opt-out. ## Affected versions and remediation This report applies to @volcengine/ark-cli@1.0.27. - Avoid installing @volcengine/ark-cli@1.0.27. 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.
