Can alter the executable and registry configuration used in ~/.grok without an explicit setup command. - **Verdict:** Malicious - **Product-default install policy:** Block - **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:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. 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. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **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 ## 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:** 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. ## Public findings ### 1. High: Install Time Lifecycle Scripts - **Category:** Manifest - **Confidence:** 90.0% - **Path:** package.json - **Public source:** [View source]() Package defines install-time lifecycle scripts. Public source snippet (untrusted): ```json scripts.postinstall = node bin/postinstall.js ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node bin/postinstall.js ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 5. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** package.json - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review. Public source snippet (untrusted): ```json stage = ast_semantic_analysis; reason = ast_parse_error; limitedFiles = 1 ``` ### 7. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **Path:** bin/postinstall.js - **Public source:** [View source]() Source file is highly similar to a previously finalized malicious package; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = normalized_sha256 matchedPackage = @kingingwang/grok@1.0.6-97098a6 matchedPath = bin/postinstall.js matchedIdentity = npm:QGtpbmdpbmd3YW5nL2dyb2s:1.0.6-97098a6 similarity = 1.000 summary = normalized source hash matched finalized malicious source ``` ### 8. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** package.json - **Public source:** [View source]() Installation automatically runs a Node postinstall program. Public source snippet (untrusted): ```json "scripts": { "postinstall": "node bin/postinstall.js" } ``` ### 9. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** bin/postinstall.js - **Public source:** [View source]() The postinstall program creates a shared ~/.grok bin directory and installs an executable there. Public source snippet (untrusted): ```javascript fs.mkdirSync(CANONICAL_DIR, { recursive: true }); ``` ### 10. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** bin/postinstall.js - **Public source:** [View source]() It rewrites ~/.grok/config.toml and records a registry value from the environment or npm configuration. Public source snippet (untrusted): ```javascript // Persist the npm registry so `shuvgrok update` and the trampoline use the // same one. const npmRegistry = process.env.GROK_NPM_REGISTRY || (() => { try { const resolved = execSync( 'npm config get @shuv1337:registry', { encoding: 'utf8', timeout: 5000 } ).trim(); if (resolved && resolved !== 'undefined') return resolved; } catch {} return null; })(); if (npmRegistry) { obj.cli.npm_registry = npmRegistry; } fs.writeFileSync(configPath, TOML.stringify(obj), 'utf8'); ``` ### 11. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** bin/postinstall.js - **Public source:** [View source]() The shared config location is explicitly described as compatible with the upstream Grok installation. Public source snippet (untrusted): ```javascript // Write installer config. Path stays ~/.grok/config.toml: that is the Rust // side's config location and is intentionally unchanged in this fork. const configDir = GROK_HOME; const configPath = path.join(configDir, 'config.toml'); ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 1 - **Optional dependencies:** 6 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 7 ### Published dependency entries - @iarna/toml ^3.0.0 (Dependency) - @shuv1337/shuvgrok-darwin-arm64 1.0.6 (OptionalDependency) - @shuv1337/shuvgrok-darwin-x64 1.0.6 (OptionalDependency) - @shuv1337/shuvgrok-linux-arm64 1.0.6 (OptionalDependency) - @shuv1337/shuvgrok-linux-x64 1.0.6 (OptionalDependency) - @shuv1337/shuvgrok-win32-arm64 1.0.6 (OptionalDependency) - @shuv1337/shuvgrok-win32-x64 1.0.6 (OptionalDependency) ## Package metadata - **Package:** @shuv1337/shuvgrok - **Ecosystem:** npm - **Version:** 1.0.6 - **License:** Apache-2.0 - **Version published:** 2026-08-31T06:12:58.803Z - **Package first seen:** 2026-08-17T00:41:56.966Z - **Package last seen:** 2026-08-31T06:20:37.735Z - **Known versions:** 3 - **Latest version:** 1.0.6 - **Appeal under review:** No - **Description:** ShuvGrok: bring Grok into your terminal - **Runtime engines:** node: \>=20 - **Supported OS:** darwin, linux, win32 - **Supported CPU:** arm64, x64 - **Artifact files:** 4 - **Artifact unpacked size:** 20,417 bytes - **Artifact signatures:** 2 - **Attestations:** Yes ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
