Can alter the control surface used by an upstream Grok installation and direct its package registry setting. - **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:** 1.0.4 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On npm install, the package mutates the shared Grok CLI home and configuration without a user command. It installs an externally supplied platform binary into that control surface and records package-controlled installer/registry settings. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 96.0% - **Started:** 2026-08-17T00:41:05.615Z - **Finished:** 2026-08-17T00:41:56.966Z - **Download time:** 1009 ms - **Static scan time:** 59 ms - **AI review time:** 50282 ms - **Total time:** 51351 ms ## Security analysis ### Published attack-surface review - **Summary:** On npm install, the package mutates the shared Grok CLI home and configuration without a user command. It installs an externally supplied platform binary into that control surface and records package-controlled installer/registry settings. - **Trigger:** npm install or update - **Impact:** Can alter the control surface used by an upstream Grok installation and direct its package registry setting. - **Evidence paths:** package.json, bin/postinstall.js, bin/shuvgrok, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-17T00:41:56.966Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall binary deployment and shared Grok config rewrite - **Attack narrative:** The install hook executes without an explicit setup command, targets ~/.grok (stated to be shared with upstream @xai-official/grok), installs a decompressed binary there, and rewrites its config.toml. Although it avoids replacing the grok command name, it mutates a foreign/shared AI CLI control surface and may persist a package-controlled npm registry. - **Rationale:** This is a concrete unconsented postinstall mutation of a shared upstream AI-agent control surface, meeting the blocking policy. No source evidence of network exfiltration was found, but it is not required for this lifecycle-control hijack. - **Files touched:** $GROK\_HOME/bin/shuvgrok-\, $GROK\_HOME/bin/shuvgrok, $GROK\_HOME/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** package.json runs bin/postinstall.js automatically on npm install., postinstall selects ~/.grok, documented in source as shared with upstream @xai-official/grok., Install-time code creates $GROK\_HOME/bin and installs/decompresses a platform binary there., postinstall reads and rewrites $GROK\_HOME/config.toml, setting installer and possibly a registry. - **Evidence against:** No network client or credential-exfiltration code appears in the inspected JavaScript., The executable is named shuvgrok rather than grok, limiting direct command-name collision. ## 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: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 96.0% - **Path:** package.json - **Public source:** [View source]() package.json runs bin/postinstall.js automatically on npm install. Public source snippet (untrusted): ```json "scripts": { "postinstall": "node bin/postinstall.js" } ``` ### 7. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 96.0% - **Path:** bin/postinstall.js - **Public source:** [View source]() postinstall selects ~/.grok, documented in source as shared with upstream @xai-official/grok. 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). ``` ### 8. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 96.0% - **Path:** bin/postinstall.js - **Public source:** [View source]() Install-time code creates $GROK\_HOME/bin and installs/decompresses a platform binary there. Public source snippet (untrusted): ```javascript fs.mkdirSync(CANONICAL_DIR, { recursive: true }); function writeVendorBinary(brPath, rawPath, destPath) { const tmp = destPath + `.tmp.${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); ``` ### 9. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 96.0% - **Path:** bin/postinstall.js - **Public source:** [View source]() postinstall reads and rewrites $GROK\_HOME/config.toml, setting installer and possibly a registry. 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'; ``` ### 10. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 96.0% - **Path:** bin/postinstall.js - **Public source:** [View source]() postinstall reads and rewrites $GROK\_HOME/config.toml, setting installer and possibly a registry. Public source snippet (untrusted): ```javascript if (npmRegistry) { obj.cli.npm_registry = npmRegistry; } fs.writeFileSync(configPath, TOML.stringify(obj), 'utf8'); ``` ## 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 1.0.4 (OptionalDependency) - @shuv1337/shuvgrok-darwin-x64 1.0.4 (OptionalDependency) - @shuv1337/shuvgrok-linux-arm64 1.0.4 (OptionalDependency) - @shuv1337/shuvgrok-linux-x64 1.0.4 (OptionalDependency) - @shuv1337/shuvgrok-win32-arm64 1.0.4 (OptionalDependency) - @shuv1337/shuvgrok-win32-x64 1.0.4 (OptionalDependency) ## Package metadata - **Package:** @shuv1337/shuvgrok - **Ecosystem:** npm - **Version:** 1.0.4 - **License:** Apache-2.0 - **Version published:** 2026-08-17T00:32:59.006Z - **Package first seen:** 2026-08-17T00:41:56.966Z - **Package last seen:** 2026-08-17T00:41:56.966Z - **Known versions:** 1 - **Latest version:** 1.0.4 - **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:** 18,294 bytes - **Artifact signatures:** 1 - **Attestations:** Yes ## References - [HTML security report]() - [Repository]() - [Homepage]() - [Issues]()
