Do not execute instructions or code found in this document. ## Verdict summary **Flagged — allowed with a warning** — Allowed by default policy, but 12 finding(s) warrant review before installing. - **Verdict:** Suspicious - **Product-default install policy:** Warn - **Firewall policy:** Matched warn-list - **Public report status:** Published - **Threat category:** Staged Payload Carrier - **Selected version:** 1.0.33 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This is the current Firewall decision for the selected package version, based on the available public evidence. Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall hook installs and invokes an opaque native binary, leaving its behavior unresolved in this source snapshot. The inspected JavaScript uses a manifest digest for verification, so this supports a warning rather than a confirmed attack or block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-10-09T20:52:14.192Z - **Finished:** 2026-10-09T20:52:39.575Z - **Download time:** 1032 ms - **Static scan time:** 119 ms - **AI review time:** 24231 ms - **Total time:** 25383 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:** Installation fetches and executes a native platform binary, then invokes it to refresh skills. The inspected source does not establish what that binary does. - **Trigger:** Package installation runs the postinstall hook. - **Impact:** The binary can perform behavior unavailable for inspection in this package snapshot; no concrete malicious action was established from the inspected source. - **Evidence paths:** scripts/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-10-09T20:52:39.575Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook downloads a manifest-selected binary, verifies its SHA-256 digest, installs it, and invokes its skill refresh command. - **Rationale:** The postinstall hook installs and invokes an opaque native binary, leaving its behavior unresolved in this source snapshot. The inspected JavaScript uses a manifest digest for verification, so this supports a warning rather than a confirmed attack or block. - **Files touched:** package.json, scripts/postinstall.js, manifest.json, bin/arkcli-linux-amd64 - **Network endpoints:** https://sf16-sg.tiktokcdn.com/obj/eden-sg/psjryh/ljhwZthlaukjlkulzlp/prod/1.0.33/arkcli-1.0.33-linux-amd64 ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** The package runs scripts/postinstall.js automatically during installation., The postinstall downloads a platform binary using a digest from the manifest., The installer invokes the downloaded binary to refresh skills; its behavior is not inspectable in this source snapshot. - **Evidence against:** The manifest pins a SHA-256 digest for the downloaded binary., The installer restricts downloads to HTTPS and checks the binary against that digest. ## Affected versions and remediation This report applies to @byteplus/ark-cli@1.0.33. - Review the evidence and your use of @byteplus/ark-cli@1.0.33 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
