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 install hook automatically invokes first-party skill setup, creating an extension lifecycle risk whose effects are not visible in the inspected source. The binary download is digest-checked and its GitHub fallback is restricted to the project’s release path, so the evidence supports a warning rather than a block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 83.0% - **Started:** 2026-10-09T20:52:27.470Z - **Finished:** 2026-10-09T20:53:22.505Z - **Download time:** 1018 ms - **Static scan time:** 114 ms - **AI review time:** 53902 ms - **Total time:** 55035 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 install lifecycle downloads a platform binary and runs its skill-refresh command. This is package-owned extension setup, but the archive’s installation effects are not inspectable in the supplied source. - **Trigger:** Package installation triggers the postinstall script; after installation it invokes the binary’s refresh command. - **Impact:** The refresh command may add or update skills; the inspected JavaScript does not establish which files or agent surfaces it changes. - **Evidence paths:** scripts/postinstall.js, manifest.json - **Review source:** ai\_review - **Reviewed:** 2026-10-09T20:53:22.505Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The script downloads the manifest-selected binary, verifies its digest, installs it, then runs the binary with +connect --refresh. - **Rationale:** The install hook automatically invokes first-party skill setup, creating an extension lifecycle risk whose effects are not visible in the inspected source. The binary download is digest-checked and its GitHub fallback is restricted to the project’s release path, so the evidence supports a warning rather than a block. - **Files touched:** scripts/postinstall.js, manifest.json - **Network endpoints:** https://sf16-sg.tiktokcdn.com/obj/eden-sg/psjryh/ljhwZthlaukjlkulzlp/prod/1.0.22/skills.tar.gz ### Review decision - **Verdict:** Suspicious - **Confidence:** 83.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The package runs a postinstall hook that downloads and installs a platform binary., After installation, the hook invokes the binary’s skill-refresh command non-interactively., The manifest provides a first-party skill archive URL and SHA-256 digest. - **Evidence against:** The installer checks downloaded binaries against manifest SHA-256 digests., The downloader requires HTTPS and restricts the GitHub fallback to this project’s release path. ## Affected versions and remediation This report applies to @byteplus/ark-cli@1.0.22. - Review the evidence and your use of @byteplus/ark-cli@1.0.22 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.
