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 a digest-checked native executable from package-aligned sources and runs it during installation. Because the executable's behavior is opaque in this source snapshot, this is an unresolved payload risk rather than evidence of a concrete attack. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-10-09T20:52:09.245Z - **Finished:** 2026-10-09T20:52:59.275Z - **Download time:** 1022 ms - **Static scan time:** 115 ms - **AI review time:** 48892 ms - **Total time:** 50030 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:** The package has an automatic postinstall hook that fetches and installs an opaque native CLI binary. It then runs that binary to refresh skills; source inspection cannot establish the behavior inside it. - **Trigger:** Installing the package through a package manager that runs postinstall. - **Impact:** The fetched executable runs during package installation, so its behavior is not auditable from the included JavaScript source. - **Evidence paths:** package.json, scripts/postinstall.js, manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-10-09T20:52:59.275Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The hook fetches the platform binary from the manifest's CDN, with a project release fallback, checks its digest, installs it, and invokes it with \`+connect --refresh\`. - **Rationale:** The postinstall hook installs a digest-checked native executable from package-aligned sources and runs it during installation. Because the executable's behavior is opaque in this source snapshot, this is an unresolved payload risk rather than evidence of a concrete attack. - **Files touched:** bin/arkcli-\-\ - **Network endpoints:** https://sf16-sg.tiktokcdn.com/obj/eden-sg/psjryh/ljhwZthlaukjlkulzlp/prod/1.0.23/arkcli-1.0.23-darwin-amd64, https://github.com/byteplus-sdk/ark-cli/releases/download/v1.0.23/arkcli-1.0.23-darwin-amd64 ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The postinstall hook downloads and installs a platform-specific executable from the package manifest., The hook checks the downloaded file against the manifest SHA-256 digest before installing it., After installation, the hook invokes the executable with \`+connect --refresh\`; that opaque binary is outside the inspected source files. - **Evidence against:** The download uses HTTPS and the stable GitHub fallback is restricted to this project's release path., The installer verifies the downloaded binary's digest before replacing the installed executable. ## Affected versions and remediation This report applies to @byteplus/ark-cli@1.0.23. - Review the evidence and your use of @byteplus/ark-cli@1.0.23 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.
