A counterfeit package can replace the executable and configuration used by an AI CLI in the user's home directory. - **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:** 1.0.24-b208f462 - **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. Installing the package runs code that installs an executable and alters the Grok user configuration under ~/.grok. The package presents itself as the unrelated @xai-official/grok tool. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 97.0% - **Started:** 2026-09-12T19:09:54.078Z - **Finished:** 2026-09-12T19:11:35.548Z - **Download time:** 762 ms - **Static scan time:** 53 ms - **AI review time:** 100655 ms - **Total time:** 101470 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:** Installing the package runs code that installs an executable and alters the Grok user configuration under ~/.grok. The package presents itself as the unrelated @xai-official/grok tool. - **Trigger:** npm installation invokes postinstall. - **Impact:** A counterfeit package can replace the executable and configuration used by an AI CLI in the user's home directory. - **Evidence paths:** package.json, bin/postinstall.js, bin/grok-bootstrap.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-09-12T19:11:35.548Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic deployment of a sibling-package binary and mutation of foreign Grok state. - **Attack narrative:** The install hook retrieves a platform executable from @kingingwang sibling packages, writes it to ~/.grok/bin, and changes ~/.grok/config.toml. The package and its launcher documentation instead identify the intended product and dependency namespace as @xai-official/grok. This namespace mismatch makes the automatic mutation of the official Grok CLI control surface unconsented and publisher-controlled. - **Rationale:** This is a counterfeit Grok package with an automatic lifecycle hook that deploys a publisher-controlled executable and alters foreign AI CLI state. The lack of direct JavaScript exfiltration does not neutralize the install-time control-surface hijack. - **Files touched:** ~/.grok/bin/grok, ~/.grok/bin/grok-\, ~/.grok/config.toml, bin/grok, bin/grok-native ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** The package automatically runs a postinstall hook., Postinstall extracts an executable from publisher-controlled sibling packages into ~/.grok/bin., Postinstall modifies ~/.grok/config.toml without an explicit user command., The launcher and README identify the tool as @xai-official/grok despite this package being @kingingwang/grok. - **Evidence against:** No network request or credential collection is implemented in the inspected JavaScript., The hook reads only a scoped npm registry setting before recording it in the Grok config. ## Affected versions and remediation This report applies to @kingingwang/grok@1.0.24-b208f462. - Avoid installing @kingingwang/grok@1.0.24-b208f462. 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.
