It hijacks the global codex AI-agent command without checking whether an existing launcher belongs to this package. - **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:** 0.153.2-codexed.1 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. A global npm install automatically replaces the existing codex command launcher. The replacement forwards future codex invocations to this package and then to a platform native binary. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 93.0% - **Started:** 2026-09-04T20:32:59.198Z - **Finished:** 2026-09-04T20:33:47.469Z - **Download time:** 758 ms - **Static scan time:** 45 ms - **AI review time:** 47467 ms - **Total time:** 48271 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install automatically replaces the existing codex command launcher. The replacement forwards future codex invocations to this package and then to a platform native binary. - **Trigger:** Global npm installation of the package. - **Impact:** It hijacks the global codex AI-agent command without checking whether an existing launcher belongs to this package. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/codex.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T20:33:47.469Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Postinstall launcher replacement and native-binary dispatch. - **Attack narrative:** Installing this package globally invokes postinstall. On POSIX systems it deletes the current prefix/bin/codex path and replaces it with a symlink to its own launcher; on Windows it writes replacement command and PowerShell launchers. Later codex invocations execute the package-selected platform binary. The code does not verify ownership of the overwritten launcher. - **Rationale:** This is an automatic postinstall mutation of a pre-existing global AI-agent command surface, rather than normal package-local bin linking. No source evidence shows network exfiltration, but the unconsented launcher overwrite is concrete install-hook abuse. - **Files touched:** /usr/local/bin/codex, codex.cmd, codex.ps1, bin/codex.js ### Review decision - **Verdict:** Malicious - **Confidence:** 93.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The package runs a postinstall hook automatically., On global installation, the hook removes the existing codex launcher and replaces it with a symlink to this package., On Windows, the hook overwrites codex.cmd and codex.ps1 to invoke this package., The runtime launcher executes a native binary supplied by platform packages. - **Evidence against:** The inspected JavaScript contains no network requests, credential harvesting, or environment exfiltration., The postinstall hook exits for non-global installs. ## 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. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/postinstall.mjs ``` ### 2. Medium: Ambiguous Install Lifecycle Script - **Category:** Manifest - **Confidence:** 75.0% - **Path:** package.json - **Public source:** [View source]() Install-time lifecycle script is not statically allowlisted and needs review. Public source snippet (untrusted): ```json scripts.postinstall = node scripts/postinstall.mjs ``` ### 3. Low: Scripts Present - **Category:** Manifest - **Confidence:** 100.0% Package declares npm scripts. ### 4. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 5. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 6. Critical: Ai Agent Control Hijack - **Category:** Source - **Confidence:** 90.0% - **Path:** scripts/postinstall.mjs - **Public source:** [View source]() Source creates an unconsented AI-agent control surface through install-time mutation or a default unauthenticated remote skill channel. Public source snippet (untrusted): ```javascript L2: L3: import { chmodSync, mkdirSync, renameSync, rmSync, symlinkSync, writeFileSync } from "node:fs"; L4: import os from "node:os"; ... L26: const launcherPath = path.join(binDir, "codex"); L27: const tmpPath = `${launcherPath}.codexed-tmp`; L28: L29: mkdirSync(binDir, { recursive: true }); L30: chmodSync(codexJs, 0o755); ... L42: L43: mkdirSync(launcherDir, { recursive: true }); L44: L45: writeFileSync( ``` ### 7. 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: Previous Version Dangerous Delta - **Category:** Supply Chain - **Confidence:** 93.0% - **Path:** bin/codex.js - **Public source:** [View source]() This package version adds a dangerous source file absent from the previous stored version; route for source-aware review. Public source snippet (untrusted): ```javascript matchType = previous_version_dangerous_delta matchedPackage = @codexed/codex@0.147.0-codexed.1 matchedIdentity = npm:QGNvZGV4ZWQvY29kZXg:0.147.0-codexed.1 similarity = 0.500 summary = stored previous version shares package body but lacks this dangerous source file ``` ### 10. High: Suspicious Lifecycle Evidence - **Category:** Manifest - **Confidence:** 93.0% - **Path:** package.json - **Public source:** [View source]() The package runs a postinstall hook automatically.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 93.0% - **Path:** scripts/postinstall.mjs - **Public source:** [View source]() On Windows, the hook overwrites codex.cmd and codex.ps1 to invoke this package. Public source snippet (untrusted): ```javascript function replaceWindowsLauncher(prefix) { const launcherDir = prefix; const cmdPath = path.join(launcherDir, "codex.cmd"); const ps1Path = path.join(launcherDir, "codex.ps1"); const escapedCodexJs = codexJs.replace(/\\/g, "\\\\"); mkdirSync(launcherDir, { recursive: true }); writeFileSync( cmdPath, `@ECHO OFF\r\nnode "${escapedCodexJs}" %*\r\n`, "utf8", ); writeFileSync( ps1Path, `#!/usr/bin/env pwsh\nnode "${escapedCodexJs}" $args\n`, "utf8", ); } ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** Yes - **Published lifecycle scripts:** postinstall - **Dependencies:** 3 - **Optional dependencies:** 3 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 6 ### Published dependency entries - @codexed/codex-linux-arm64 0.153.2-codexed.1 (Dependency) - @codexed/codex-linux-x64 0.153.2-codexed.1 (Dependency) - @codexed/codex-win32-x64 0.153.2-codexed.1 (Dependency) - @codexed/codex-linux-arm64 0.153.2-codexed.1 (OptionalDependency) - @codexed/codex-linux-x64 0.153.2-codexed.1 (OptionalDependency) - @codexed/codex-win32-x64 0.153.2-codexed.1 (OptionalDependency) ## Package metadata - **Package:** @codexed/codex - **Ecosystem:** npm - **Version:** 0.153.2-codexed.1 - **License:** Apache-2.0 - **Version published:** 2026-09-04T01:19:05.806Z - **Package first seen:** 2026-07-01T04:33:12.271Z - **Package last seen:** 2026-09-04T20:33:47.469Z - **Known versions:** 17 - **Latest version:** 0.153.2-codexed.1 - **Appeal under review:** No - **Description:** \
