A third-party fork can persist its distribution settings in the upstream Grok control surface and influence subsequent fork-managed updates. - **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:** 1.0.5 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Installing the package automatically mutates the shared upstream Grok home. It places a sibling-package binary there and persists installer/registry settings in the shared config. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 94.0% - **Started:** 2026-08-17T23:35:27.713Z - **Finished:** 2026-08-17T23:36:02.836Z - **Download time:** 777 ms - **Static scan time:** 58 ms - **AI review time:** 34287 ms - **Total time:** 35123 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically mutates the shared upstream Grok home. It places a sibling-package binary there and persists installer/registry settings in the shared config. - **Trigger:** npm install invokes postinstall - **Impact:** A third-party fork can persist its distribution settings in the upstream Grok control surface and influence subsequent fork-managed updates. - **Evidence paths:** package.json, bin/postinstall.js, bin/shuvgrok - **Review source:** ai\_review - **Reviewed:** 2026-08-17T23:36:02.836Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall binary deployment and shared AI-agent config mutation - **Attack narrative:** On npm install, the package's postinstall hook creates the shared \`~/.grok/bin\` directory, decompresses or copies an opaque platform sibling binary into it, and writes \`cli.installer\` plus a registry setting to \`~/.grok/config.toml\`. The source explicitly acknowledges that this location is shared with \`@xai-official/grok\`. This is an unconsented install-time mutation of a foreign AI-agent CLI control surface. - **Rationale:** The source establishes a concrete automatic persistence and configuration-mutation chain in an upstream Grok home, not merely a scanner signature. Lack of direct exfiltration does not mitigate this foreign control-surface write. Product guard normalized a concrete AI-agent control hijack publish\_block to the blockable dangerous-capability shape. - **Files touched:** bin/postinstall.js, ~/.grok/bin/shuvgrok, ~/.grok/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 94.0% - **Recommended action:** publish\_block - **Intent class:** Dangerous Capability - **False-positive risk:** Low - **Evidence for:** \`postinstall\` runs automatically on npm install., Install code deliberately uses the upstream Grok home and shared config path., The lifecycle hook writes \`cli.installer\` and a registry value into \`~/.grok/config.toml\`., It silently installs a compressed sibling-package binary into \`~/.grok/bin\`. - **Evidence against:** No credential harvesting or network request is present in the inspected JavaScript., The installed command is named \`shuvgrok\`, reducing direct command-name collision. ## Public findings ### 1.

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: 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 = @shuv1337/shuvgrok@1.0.4 matchedPath = bin/postinstall.js matchedIdentity = npm:QHNodXYxMzM3L3NodXZncm9r:1.0.4 similarity = 1.000 summary = normalized source hash matched finalized malicious source ``` ### 7. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **Path:** bin/shuvgrok - **Public source:** [View source]() Source file is highly similar to a previously finalized malicious package; route for source-aware review. Public source snippet (untrusted): ```text matchType = normalized_sha256 matchedPackage = @shuv1337/shuvgrok@1.0.4 matchedPath = bin/shuvgrok matchedIdentity = npm:QHNodXYxMzM3L3NodXZncm9r:1.0.4 similarity = 1.000 summary = normalized source hash matched finalized malicious source ``` ### 8. High: Known Malware Source Fingerprint Signature - **Category:** Supply Chain - **Confidence:** 94.0% - **Path:** bin/postinstall.js - **Public source:** [View source]() Source fingerprint signature matches a known malicious package signature; route for source-aware review.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** bin/postinstall.js - **Public source:** [View source]() Install code deliberately uses the upstream Grok home and shared config path. Public source snippet (untrusted): ```javascript // The binary is deliberately named `shuvgrok`, not `grok`: ~/.grok is shared // with an upstream @xai-official/grok install, and a `grok` symlink there // would collide with it. Only the config file path stays `~/.grok/config.toml` // (read by the Rust side, which is unchanged in this fork). ``` ### 11. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 94.0% - **Path:** bin/postinstall.js - **Public source:** [View source]() The lifecycle hook writes \`cli.installer\` and a registry value into \`~/.grok/config.toml\`. 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'); let obj = {}; try { obj = TOML.parse(fs.readFileSync(configPath, 'utf8')); } catch { } obj.cli ??= {}; obj.cli.installer = 'npm'; // 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 ``` ### 12. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 94.0% - **Path:** bin/postinstall.js - **Public source:** [View source]() It silently installs a compressed sibling-package binary into \`~/.grok/bin\`. Public source snippet (untrusted): ```javascript fs.mkdirSync(CANONICAL_DIR, { recursive: true }); function writeVendorBinary(brPath, rawPath, destPath) { const tmp = destPath + `.tmp.${process.pid}`; try { if (fs.existsSync(brPath)) { fs.writeFileSync(tmp, zlib.brotliDecompressSync(fs.readFileSync(brPath))); } else if (fs.existsSync(rawPath)) { fs.copyFileSync(rawPath, tmp); } else { return false; } if (!IS_WINDOWS) fs.chmodSync(tmp, 0o755); fs.renameSync(tmp, destPath); ``` ## 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 1.0.5 (OptionalDependency) - @shuv1337/shuvgrok-darwin-x64 1.0.5 (OptionalDependency) - @shuv1337/shuvgrok-linux-arm64 1.0.5 (OptionalDependency) - @shuv1337/shuvgrok-linux-x64 1.0.5 (OptionalDependency) - @shuv1337/shuvgrok-win32-arm64 1.0.5 (OptionalDependency) - @shuv1337/shuvgrok-win32-x64 1.0.5 (OptionalDependency) ## Package metadata - **Package:** @shuv1337/shuvgrok - **Ecosystem:** npm - **Version:** 1.0.5 - **License:** Apache-2.0 - **Version published:** 2026-08-17T23:35:00.382Z - **Package first seen:** 2026-08-17T00:41:56.966Z - **Package last seen:** 2026-08-17T23:36:02.836Z - **Known versions:** 2 - **Latest version:** 1.0.5 - **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:** 18,286 bytes - **Artifact signatures:** 1 - **Attestations:** Yes ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
