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. LPM treats this as warn-only first-party agent extension lifecycle risk. Installation writes a versioned Grok executable and a Grok-specific configuration file under the user's .grok directory. This is a package-owned AI CLI control surface, but the reviewed JavaScript shows no exfiltration or network activity. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 78.0% - **Started:** 2026-08-29T09:10:22.158Z - **Finished:** 2026-08-29T09:11:05.524Z - **Download time:** 761 ms - **Static scan time:** 54 ms - **AI review time:** 42550 ms - **Total time:** 43366 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:** Installation writes a versioned Grok executable and a Grok-specific configuration file under the user's .grok directory. This is a package-owned AI CLI control surface, but the reviewed JavaScript shows no exfiltration or network activity. - **Trigger:** npm installation or update runs the postinstall hook. - **Impact:** An install can replace the local Grok executable and persist its selected registry in .grok/config.toml. - **Evidence paths:** package.json, bin/postinstall.js, bin/grok - **Review source:** ai\_review - **Reviewed:** 2026-08-29T09:11:05.524Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Copies or decompresses a sibling platform binary and updates Grok CLI configuration. - **Rationale:** The package performs automatic installation-time mutation of a package-owned Grok CLI directory and installs an opaque companion binary. No concrete theft, remote execution, broad agent-control mutation, or lifecycle self-dependency was found in the reviewed source. - **Files touched:** ~/.grok/bin/grok, ~/.grok/bin/grok-\, ~/.grok/config.toml, node\_modules/@kingingwang/grok-\/bin/grok ### Review decision - **Verdict:** Suspicious - **Confidence:** 78.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for warning:** The automatic postinstall hook installs a platform binary into the user's .grok directory., The installer updates .grok/config.toml and records an npm registry setting., The package fetches its executable payload from separately published platform packages, whose binary contents are not present for source review. - **Evidence against:** The reviewed JavaScript contains no network request or credential/file harvesting logic., The only shell command reads a scoped npm registry configuration., Platform dependencies are pinned to this exact version; there is no runtime dependency on this package itself., Completion generation requires an explicit environment variable. ## Affected versions and remediation This report applies to @kingingwang/grok@1.0.10-6f4ddbd. - Review the evidence and your use of @kingingwang/grok@1.0.10-6f4ddbd 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.
