Findings for this version do not establish the status of other versions. AI assessment: suspicious; recommendation: downgrade to warn. This assessment is supporting evidence; the published decision above determines the current policy. Installing the package extracts a compressed executable from a platform-specific optional dependency into the user's Grok directory. The executable is then launched by the grok command wrapper, but its contents are not available in this package for inspection. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Suspicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-08-29T19:19:04.505Z - **Finished:** 2026-08-29T19:19:46.043Z - **Download time:** 763 ms - **Static scan time:** 52 ms - **AI review time:** 40722 ms - **Total time:** 41538 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installing the package extracts a compressed executable from a platform-specific optional dependency into the user's Grok directory. The executable is then launched by the grok command wrapper, but its contents are not available in this package for inspection. - **Trigger:** npm installation runs postinstall; invoking grok launches the extracted executable. - **Impact:** An uninspectable native payload is placed in the user profile and can run under the invoking user's permissions. - **Evidence paths:** package.json, bin/postinstall.js, bin/grok, README.md - **Review source:** ai\_review - **Reviewed:** 2026-08-29T19:19:46.043Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Automatic installation and later execution of an opaque sibling-package binary. - **Rationale:** This is an automatically installed opaque payload carrier with publisher-identity inconsistency, so a warning is warranted. The inspected source does not establish concrete malicious behavior sufficient for a block. - **Files touched:** $GROK\_HOME/bin/grok, $GROK\_HOME/bin/grok-\, $GROK\_HOME/config.toml ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for warning:** An automatic postinstall hook runs package code during npm installation., The hook decompresses an opaque platform-package binary into the user's Grok directory., The command wrapper executes that extracted binary when the grok command is used., The README directs users to a different npm scope, which is consistent with impersonation risk. - **Evidence against:** The inspected JavaScript has no secret harvesting, HTTP client, or data upload logic., The only shell command reads the configured npm registry; it does not fetch or execute a remote payload., Writes are limited to the package's Grok directory and its configuration file., Optional completion generation runs only when the user environment explicitly enables it. ## Affected versions and remediation This report applies to @kingingwang/grok@1.0.12-8d051d60. - Review the evidence and your use of @kingingwang/grok@1.0.12-8d051d60 before allowing it. Restrict the permissions described in this report. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. ## Public findings ### 1.
