Its launcher claims the official @xai-official/grok identity and runs that binary. - **Trigger:** npm installation runs the postinstall hook; invoking grok runs the installed binary. - **Impact:** An unconsented install can replace the executable and configuration used by a separate AI CLI control surface. - **Evidence paths:** package.json, bin/postinstall.js, bin/grok-bootstrap.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T00:48:39.144Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall binary replacement and configuration mutation of ~/.grok. - **Attack narrative:** The package name is @kingingwang/grok, but its launcher identifies itself as @xai-official/grok. On every npm installation, its postinstall creates ~/.grok/bin, extracts a binary supplied by same-scope optional dependencies, makes it the canonical grok executable, and writes ~/.grok/config.toml. The launcher then executes the resolved binary. This silently alters the installed state of the official-looking Grok CLI rather than merely exposing a package-local command. - **Rationale:** This is a typosquatting package with an automatic lifecycle hook that writes and replaces executables in a foreign AI CLI home directory. The identity mismatch and unconsented control-surface mutation establish malicious install-hook abuse. - **Files touched:** ~/.grok/bin/grok, ~/.grok/bin/grok-\, ~/.grok/config.toml, bin/grok, bin/grok-native ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest uses an automatic postinstall hook despite presenting a different package identity from the official Grok CLI., The postinstall hook creates ~/.grok/bin, extracts a platform binary there, and writes ~/.grok/config.toml without an explicit user command., The launcher identifies itself as @xai-official/grok and executes the resolved binary, while this package is @kingingwang/grok. - **Evidence against:** No credential harvesting, network request, or remote payload download is present in the inspected JavaScript., The code contains a functional platform-binary installer rather than obfuscated JavaScript. ## Public findings ### 1.
