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. This is a transparent but automatic remote-binary installer with silent host and session telemetry. No source evidence establishes secret theft, broad persistence, agent-control mutation, or an unverified payload chain, so blocking is not warranted. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-08-31T08:50:17.513Z - **Finished:** 2026-08-31T08:51:17.281Z - **Download time:** 505 ms - **Static scan time:** 211 ms - **AI review time:** 59051 ms - **Total time:** 59768 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 a platform executable and overwrites its package-local CLI binary. The installer also transmits installation telemetry containing host and session-related metadata. - **Trigger:** npm runs postinstall during package installation. - **Impact:** A remote artifact selected by package metadata becomes the CLI executable; installation metadata is sent to a third-party logging host. - **Evidence paths:** package.json, binaries.json, install.cjs - **Review source:** ai\_review - **Reviewed:** 2026-08-31T08:51:17.281Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary staging with silent installation telemetry. - **Rationale:** This is a transparent but automatic remote-binary installer with silent host and session telemetry. No source evidence establishes secret theft, broad persistence, agent-control mutation, or an unverified payload chain, so blocking is not warranted. - **Files touched:** binaries.json, bin/kry-cli.exe, package.json - **Network endpoints:** s.koubei.com, tnnm-alsc-saas-merchant-spider-fy21.cn-wulanchabu.log.aliyuncs.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 91.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The automatic postinstall hook downloads and replaces the CLI binary., The downloaded executable is opaque to this source review and is fetched from a remote CDN., Postinstall silently sends host, user-path-derived, session, and npm environment metadata to a logging endpoint. - **Evidence against:** The downloader verifies both compressed and decompressed SHA-256 values before writing the binary., Writes are limited to the package's bin/kry-cli.exe path; no broad project or agent-configuration mutation was found., No self-dependency, secret-file harvesting, shell payload execution, or evaluator-directed text was found. ## Affected versions and remediation This report applies to @keruyun/agent-cli@1.4.16. - Review the evidence and your use of @keruyun/agent-cli@1.4.16 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.
