An unconsented third-party package can replace the executable and configuration used by the Grok CLI. - **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:** 1.0.6-97098a6 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. npm postinstall silently installs a sibling-package binary and rewrites Grok's default user control directory. The package identity conflicts with the README's stated official package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 97.0% - **Started:** 2026-08-20T16:50:39.999Z - **Finished:** 2026-08-20T16:51:17.690Z - **Download time:** 502 ms - **Static scan time:** 48 ms - **AI review time:** 37141 ms - **Total time:** 37691 ms ## Security analysis ### Published attack-surface review - **Summary:** npm postinstall silently installs a sibling-package binary and rewrites Grok's default user control directory. The package identity conflicts with the README's stated official package. - **Trigger:** npm install or update - **Impact:** An unconsented third-party package can replace the executable and configuration used by the Grok CLI. - **Evidence paths:** package.json, bin/postinstall.js, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-20T16:51:17.690Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall binary deployment and ~/.grok config mutation - **Attack narrative:** Installing this non-officially scoped package automatically creates the default Grok home, writes a decompressed platform payload as ~/.grok/bin/grok, and updates ~/.grok/config.toml. Because the README itself identifies @xai-official/grok as the official npm package, this is an unconsented foreign package mutating a shared AI CLI control surface during postinstall. - **Rationale:** The install hook mutates the user-wide Grok binary and config without an explicit command, while the package's README points users to a different official scope. This is a concrete foreign AI-agent control-surface takeover pattern despite no direct network logic in the JavaScript. - **Files touched:** bin/postinstall.js, ~/.grok/bin/grok, ~/.grok/config.toml ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Install lifecycle runs a local postinstall script., Postinstall writes a platform payload into the default ~/.grok/bin control directory., Postinstall modifies ~/.grok/config.toml without user action., README claims the official package is @xai-official/grok, not this package. - **Evidence against:** The JavaScript contains no direct network request or credential-harvesting logic., Completion generation executes only when GROK\_INSTALL\_COMPLETIONS=1. ## Public findings ### 1.
