An existing Grok CLI install can be replaced so later grok commands run the binary shipped by this publisher. - **Verdict:** AI-agent control-surface policy finding - **Product-default install policy:** Warn by default; block when configured - **Firewall policy:** Warn by default - **Public report status:** Published - **Threat category:** Soft block: AI-agent control surface - **Selected version:** 1.0.32-aae58918 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) This finding concerns changes to an AI agent's instructions or configuration without explicit user action. It does not by itself establish malware intent. The CLI warns by default and blocks when configured for this policy. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. LPM flags this version as an AI-agent control-surface risk. On npm install, postinstall drops a native grok binary into the official Grok CLI home and rewrites its config. That is an unconsented change to a foreign AI-agent control surface from a non-official scope. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-19T00:52:36.417Z - **Finished:** 2026-09-19T00:58:27.979Z - **Download time:** 760 ms - **Static scan time:** 64 ms - **AI review time:** 350738 ms - **Total time:** 351562 ms The recorded confidence comes from the underlying analysis.

That is an unconsented change to a foreign AI-agent control surface from a non-official scope. - **Trigger:** npm install of @kingingwang/grok, which runs the postinstall script with no extra user command. - **Impact:** An existing Grok CLI install can be replaced so later grok commands run the binary shipped by this publisher. - **Evidence paths:** package.json, bin/postinstall.js, bin/grok-bootstrap.js - **Review source:** ai\_review - **Reviewed:** 2026-09-19T00:58:27.979Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** install-time write of a vendor binary and config into ~/.grok - **Attack narrative:** On npm install, postinstall.js copies a native binary from the @kingingwang/grok platform optional dependency into ~/.grok/bin and rewrites ~/.grok/config.toml. That directory is the official Grok CLI home, so this silent hook can replace an existing grok binary and take over later grok commands. The package is published under the kingingwang scope while the launcher still looks up official @xai-official/grok platform packages, which is impersonation rather than a first-party installer. - **Rationale:** Automatic postinstall writes a native binary and config into ~/.grok, a foreign Grok agent control surface, from a different npm scope. That unconsented install-time hijack is concrete attack behavior and should be blocked. - **Files touched:** ~/.grok/bin/grok, ~/.grok/config.toml, bin/grok, bin/grok-native ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** Automatic postinstall runs node bin/postinstall.js on npm install., Postinstall extracts a native grok binary into the user home .grok/bin directory, which is the official Grok CLI location., Postinstall reads and rewrites .grok/config.toml, setting installer metadata and an npm registry., The published name is @kingingwang/grok while README and the launcher still present official @xai-official/grok branding., Optional platform packages named @kingingwang/grok-\-\ supply the native binary dropped at install time. - **Evidence against:** This tarball's JavaScript does not harvest credentials or open network sockets., The native binary payload is not in this package; it is expected from optionalDependencies., The package does not depend on another release of its own name. ## Affected versions and remediation This report applies to @kingingwang/grok@1.0.32-aae58918. - Avoid installing @kingingwang/grok@1.0.32-aae58918. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
