Existing \`codex\` invocations are redirected to the package's binary. - **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:** 0.149.0-codexed.3 - **Selected version is latest:** No - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. On global npm installation, the postinstall script deletes the existing \`codex\` launcher and replaces it with a launcher to this package. This hijacks a broad AI-agent CLI control surface without user confirmation. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-22T22:58:08.768Z - **Finished:** 2026-08-22T22:58:47.996Z - **Download time:** 507 ms - **Static scan time:** 41 ms - **AI review time:** 38680 ms - **Total time:** 39228 ms ## Security analysis ### Published attack-surface review - **Summary:** On global npm installation, the postinstall script deletes the existing \`codex\` launcher and replaces it with a launcher to this package. This hijacks a broad AI-agent CLI control surface without user confirmation. - **Trigger:** npm global installation - **Impact:** Existing \`codex\` invocations are redirected to the package's binary. - **Evidence paths:** package.json, scripts/postinstall.mjs, README.md, bin/codex.js - **Review source:** ai\_review - **Reviewed:** 2026-08-22T22:58:47.996Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall replacement of the global \`codex\` command - **Attack narrative:** Installing this differently scoped package globally runs postinstall. On POSIX it recursively removes \`\/bin/codex\` and replaces it with a symlink to its own launcher; on Windows it overwrites \`codex.cmd\` and \`codex.ps1\`. The package claims to be OpenAI Codex in its README despite its \`@codexed\` identity. This unconsented install-time replacement redirects the primary Codex command to package-controlled binaries. - **Rationale:** The install hook deliberately overwrites an existing global AI-agent command rather than relying on npm's normal bin linking. That is a concrete unconsented control-surface hijack. - **Files touched:** scripts/postinstall.mjs, bin/codex.js, \/bin/codex, \/codex.cmd, \/codex.ps1 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Global-install postinstall executes automatically., It forcibly removes and replaces the global \`codex\` launcher., Package identity and bundled dependencies use \`@codexed\`, while README presents it as OpenAI Codex. - **Evidence against:** No network, credential-harvesting, or shell-download code is present in the inspected JavaScript., The runtime launcher only starts a locally resolved platform binary. ## 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.

Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 95.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 8. Critical: Manifest Confusion - **Category:** Manifest - **Confidence:** 95.0% - **Path:** package.json - **Public source:** [View source]() Tarball package.json differs from the npm registry version manifest for scripts or dependency sets. Public source snippet (untrusted): ```json dependencies registry_only=@codexed/codex-linux-arm64,@codexed/codex-linux-x64,@codexed/codex-win32-x64 ``` ### 9. High: Known Malware Source Similarity - **Category:** Static - **Confidence:** 97.0% - **Path:** bin/codex.js - **Public source:** [View source]() Source file is highly similar to a previously finalized malicious package; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = normalized_sha256 matchedPackage = @codexed/codex@0.149.0-codexed.2 matchedPath = bin/codex.js matchedIdentity = npm:QGNvZGV4ZWQvY29kZXg:0.149.0-codexed.2 similarity = 1.000 summary = normalized source hash matched finalized malicious source ``` ### 10.
