Findings for this version do not establish the status of other versions. AI assessment: clean; recommendation: mark clean. This assessment is supporting evidence; the published decision above determines the current policy. The postinstall hook is a readable Keruyun CLI installer that downloads hash-pinned binaries from s.koubei.com into this package's own bin path and optionally reports install metrics to Aliyun SLS. Scanner malware-fingerprint and native-binary labels are noisy: the tarball kry-cli.exe is a placeholder stub, and there is no foreign agent-config write, secret harvest, or self-dependency chain. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Clean - **Recorded analysis confidence:** 86.0% - **Started:** 2026-09-17T13:31:18.693Z - **Finished:** 2026-09-17T13:35:18.598Z - **Download time:** 505 ms - **Static scan time:** 271 ms - **AI review time:** 239129 ms - **Total time:** 239905 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:** Inspected source is a first-party Keruyun CLI shell: postinstall downloads a hash-pinned platform binary into this package's own bin path and may send install metrics to Aliyun SLS. That is package-aligned native CLI setup, not a confirmed attack. - **Trigger:** npm install runs postinstall; the krycli binary and SDK run only after that install or an explicit import. - **Impact:** No confirmed credential theft, foreign agent hijack, or consumer-project mutation. - **Review source:** ai\_review - **Reviewed:** 2026-09-17T13:35:18.598Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** hash-pinned CDN binary install plus optional install telemetry - **Rationale:** The postinstall hook is a readable Keruyun CLI installer that downloads hash-pinned binaries from s.koubei.com into this package's own bin path and optionally reports install metrics to Aliyun SLS. Scanner malware-fingerprint and native-binary labels are noisy: the tarball kry-cli.exe is a placeholder stub, and there is no foreign agent-config write, secret harvest, or self-dependency chain. ### Review decision - **Verdict:** Clean - **Confidence:** 86.0% - **Recommended action:** mark\_clean - **Intent class:** Benign - **False-positive risk:** Medium - **Evidence for AI clean decision:** postinstall runs node install.cjs, which fetches a remote brotli binary and overwrites this package's bin/kry-cli.exe, install telemetry POSTs hostname, npm metadata, AGENT\_WORK\_ROOT user id, and REWIND\_SESSION\_ID to Aliyun SLS, sdk.mjs is a large minified bundle, and scanners flagged installer similarity to a previously blocked package - **Evidence against:** CDN URLs and sha256 hashes are pinned in binaries.json; the installer writes only bin/kry-cli.exe inside this package after verifying both the compressed and decompressed bytes, the shipped bin/kry-cli.exe is a text placeholder stub, not a native implant, network hosts are Keruyun, Koubei, and Aliyun product endpoints; telemetry is opt-out via KRY\_CLI\_NO\_TRACK, no foreign AI-agent config writes, no secret-file harvest, no runtime self-dependency, and no obfuscated install script ## Affected versions and remediation This report applies to @keruyun/agent-cli@1.5.7. - Review the evidence and your use of @keruyun/agent-cli@1.5.7 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.
