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 package performs unconsented install-time telemetry collection and stages an opaque remote executable as its command. Hash validation limits CDN substitution but does not remove the data-exfiltration and opaque-payload attack surface. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 96.0% - **Started:** 2026-09-05T08:44:43.410Z - **Finished:** 2026-09-05T08:45:53.095Z - **Download time:** 769 ms - **Static scan time:** 381 ms - **AI review time:** 68534 ms - **Total time:** 69685 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:** Every npm installation downloads and stages an opaque native executable. The same automatic hook silently transmits installation and agent-context metadata. - **Trigger:** Installing the package with npm lifecycle scripts enabled. - **Impact:** A remote native payload becomes the krycli command, while host, session, user-ID-derived, and npm metadata leave the machine without an interactive consent prompt. - **Evidence paths:** package.json, install.cjs, binaries.json - **Review source:** ai\_review - **Reviewed:** 2026-09-05T08:45:53.095Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall binary staging and telemetry exfiltration. - **Rationale:** The package performs unconsented install-time telemetry collection and stages an opaque remote executable as its command. Hash validation limits CDN substitution but does not remove the data-exfiltration and opaque-payload attack surface. Product guard normalized a non-low false-positive publish\_block request to warn-only suspicious. - **Files touched:** binaries.json, install.cjs, bin/kry-cli.exe - **Network endpoints:** s.koubei.com, tnnm-alsc-saas-merchant-spider-fy21.cn-wulanchabu.log.aliyuncs.com ### Review decision - **Verdict:** Suspicious - **Confidence:** 96.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Malware - **False-positive risk:** Medium - **Evidence for warning:** An automatic postinstall hook runs install.cjs., The hook collects hostname, agent-work-root-derived user ID, session ID, and npm installation metadata., It silently posts that data to a third-party log endpoint unless an undocumented environment opt-out is set., It downloads a large platform-native payload from a CDN, verifies pinned hashes, and replaces the package command with an executable binary. - **Evidence against:** The downloaded artifacts are pinned by SHA-256 values in the published manifest., The inspected installer does not read credentials or modify files outside its own bin directory. ## Affected versions and remediation This report applies to @keruyun/agent-cli@1.5.2. - Review the evidence and your use of @keruyun/agent-cli@1.5.2 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.
