Can alter the executable and registry configuration used in ~/.grok without an explicit setup command. - **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:** 1.0.6 - **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. The automatic lifecycle hook modifies the shared ~/.grok executable and configuration surface, including registry selection. No direct exfiltration is present in the inspected JavaScript, but the install-time control-surface mutation is concrete and sufficient to block. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 94.0% - **Started:** 2026-08-31T06:19:58.497Z - **Finished:** 2026-08-31T06:20:37.735Z - **Download time:** 758 ms - **Static scan time:** 52 ms - **AI review time:** 38427 ms - **Total time:** 39238 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:** A package installation automatically writes an executable and configuration into the shared Grok home directory. This changes a control surface also used by the upstream Grok client. - **Trigger:** npm installation or update - **Impact:** Can alter the executable and registry configuration used in ~/.grok without an explicit setup command. - **Evidence paths:** package.json, bin/postinstall.js - **Review source:** ai\_review - **Reviewed:** 2026-08-31T06:20:37.735Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall deployment and shared AI-client configuration mutation - **Attack narrative:** Installing the package invokes postinstall automatically. That code materializes an opaque platform binary under ~/.grok/bin and modifies ~/.grok/config.toml, a location it identifies as shared with the upstream Grok client. It also persists a registry setting derived from GROK\_NPM\_REGISTRY or npm configuration. This is an unconsented install-time mutation of a foreign/shared AI-agent control surface. - **Rationale:** The automatic lifecycle hook modifies the shared ~/.grok executable and configuration surface, including registry selection. No direct exfiltration is present in the inspected JavaScript, but the install-time control-surface mutation is concrete and sufficient to block. - **Files touched:** ~/.grok/bin/shuvgrok-\, ~/.grok/bin/shuvgrok, ~/.grok/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for policy risk:** Installation automatically runs a Node postinstall program., The postinstall program creates a shared ~/.grok bin directory and installs an executable there., It rewrites ~/.grok/config.toml and records a registry value from the environment or npm configuration., The shared config location is explicitly described as compatible with the upstream Grok installation. - **Evidence against:** The inspected JavaScript contains no direct network request or credential-exfiltration code., The platform payload is resolved from fixed optional dependencies rather than a runtime download. ## Affected versions and remediation This report applies to @shuv1337/shuvgrok@1.0.6. - Avoid installing @shuv1337/shuvgrok@1.0.6. 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.
