It removes the existing launcher and redirects it to this differently named package. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 97.0% - **Started:** 2026-09-05T01:19:18.108Z - **Finished:** 2026-09-05T01:19:58.756Z - **Download time:** 1009 ms - **Static scan time:** 42 ms - **AI review time:** 39596 ms - **Total time:** 40648 ms ## Security analysis ### Published attack-surface review - **Summary:** A postinstall hook automatically takes over the global codex launcher. It removes the existing launcher and redirects it to this differently named package. - **Trigger:** Global npm installation. - **Impact:** It can silently redirect future codex invocations to this package. - **Evidence paths:** package.json, scripts/postinstall.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-05T01:19:58.756Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall replacement of a foreign global AI CLI launcher. - **Attack narrative:** Installing the package globally invokes its postinstall script. The script selects the npm global prefix, deletes the existing codex launcher, and replaces it with a symlink or Windows wrapper that runs this package's entry point. Because the package is under the distinct @codexed scope, this is an unconsented takeover of a foreign AI-agent command surface. - **Rationale:** The automatic lifecycle hook overwrites a global AI CLI command owned outside this package rather than only configuring package-owned files. The absence of observed network or credential behavior does not remove the launcher-hijack risk. - **Files touched:** scripts/postinstall.mjs, package.json, \/bin/codex, \/bin/codex.codexed-tmp, \/codex.cmd, \/codex.ps1 ### Review decision - **Verdict:** Malicious - **Confidence:** 97.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Its postinstall hook runs automatically on installation., For global installs, it deletes the existing codex launcher and replaces it with a symlink to this package., The package is @codexed/codex but takes over the generic codex command used by another vendor's AI CLI. - **Evidence against:** The hook does not run for non-global installs., No network access, credential collection, or payload download appears in the inspected JavaScript. ## Public findings ### 1.
