Later grok invocations can run the publisher's binary, and an existing official CLI install under ~/.grok can be overwritten. - **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:** 1.0.35-7096013f - **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 extracts a native grok binary from @kingingwang platform packages and writes it into ~/.grok/bin, then updates ~/.grok/config.toml. That is the official Grok CLI home, so an existing grok install can be replaced without a separate user command. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 93.0% - **Started:** 2026-09-18T23:03:20.114Z - **Finished:** 2026-09-18T23:11:23.832Z - **Download time:** 509 ms - **Static scan time:** 70 ms - **AI review time:** 483138 ms - **Total time:** 483718 ms The recorded confidence comes from the underlying analysis.

That is the official Grok CLI home, so an existing grok install can be replaced without a separate user command. - **Trigger:** npm install of @kingingwang/grok runs the postinstall script. - **Impact:** Later grok invocations can run the publisher's binary, and an existing official CLI install under ~/.grok can be overwritten. - **Evidence paths:** package.json, bin/postinstall.js, bin/grok-bootstrap.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-09-18T23:11:23.832Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time drop of a native grok binary and config into the official Grok home directory - **Attack narrative:** This package impersonates the official Grok CLI while publishing as @kingingwang/grok. After npm install, postinstall.js extracts a native binary from @kingingwang/grok platform packages, installs it to ~/.grok/bin, and rewrites ~/.grok/config.toml. That directory belongs to the official Grok CLI, so an existing grok install can be replaced with no extra command. README and grok-bootstrap.js still name @xai-official/grok, showing a cloned official launcher under another npm scope. Running grok then executes the dropped binary. - **Rationale:** This is a cloned official Grok CLI wrapper published as @kingingwang/grok. Its postinstall automatically plants a native binary and config into ~/.grok, hijacking another vendor's Grok CLI control surface. - **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:** Package.json names this @kingingwang/grok, registers a grok binary, and runs node bin/postinstall.js automatically after install., optionalDependencies pull same-version @kingingwang/grok platform packages that supply the native payload., postinstall.js resolves ~/.grok/bin and installs a versioned grok binary plus a canonical grok link or copy there., postinstall.js reads and rewrites ~/.grok/config.toml, setting installer to npm and storing an npm registry., grok-bootstrap.js still identifies the product as @xai-official/grok and resolves official platform packages., README copies official xAI Grok CLI docs and tells users to install @xai-official/grok. - **Evidence against:** The JavaScript does not fetch secrets or contact a hardcoded exfiltration host., Shell completion files are written only when GROK\_INSTALL\_COMPLETIONS=1., The wrapper layout resembles a normal per-platform CLI installer. ## Affected versions and remediation This report applies to @kingingwang/grok@1.0.35-7096013f. - Avoid installing @kingingwang/grok@1.0.35-7096013f. 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.
