Hijacks a broad AI-agent CLI control surface and causes future \`codex\` invocations to execute package-selected binaries. - **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.7 - **Selected version is latest:** Yes - **Analysis source:** AI Security Review (lpm-firewall-ai) LPM flags this version as an AI-agent control-surface risk. Global installation automatically replaces the system-wide \`codex\` command with this package's launcher. It can delete an existing launcher and directs later Codex use to @codexed binaries. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 95.0% - **Started:** 2026-08-23T09:41:46.097Z - **Finished:** 2026-08-23T09:42:33.961Z - **Download time:** 504 ms - **Static scan time:** 40 ms - **AI review time:** 47319 ms - **Total time:** 47864 ms ## Security analysis ### Published attack-surface review - **Summary:** Global installation automatically replaces the system-wide \`codex\` command with this package's launcher. It can delete an existing launcher and directs later Codex use to @codexed binaries. - **Trigger:** npm global installation - **Impact:** Hijacks a broad AI-agent CLI control surface and causes future \`codex\` invocations to execute package-selected binaries. - **Evidence paths:** package.json, scripts/postinstall.mjs, bin/codex.js - **Review source:** ai\_review - **Reviewed:** 2026-08-23T09:42:33.961Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall overwrites global Codex launchers - **Attack narrative:** During global installation, the postinstall hook derives the npm prefix (defaulting to /usr/local), removes an existing \`codex\` launcher, and replaces it with a link or Windows scripts invoking this package. Subsequent user execution of \`codex\` resolves and spawns a binary from @codexed platform packages. This is an unconsented install-time takeover of the globally named Codex agent command. - **Rationale:** Source inspection confirms a postinstall hook that overwrites a pre-existing global Codex launcher, rather than relying on package-manager-owned bin linking. That creates a concrete broad AI-agent control-surface hijack. - **Files touched:** scripts/postinstall.mjs, bin/codex.js, \/bin/codex, \/codex.cmd, \/codex.ps1 ### Review decision - **Verdict:** Malicious - **Confidence:** 95.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** postinstall executes automatically on installation., On global installs it selects npm prefix or defaults to /usr/local., It deletes the existing global \`codex\` launcher before replacing it with a symlink to this package., On Windows it overwrites \`codex.cmd\` and \`codex.ps1\` to invoke this package., The replacement command launches a platform binary from @codexed packages. - **Evidence against:** Inspected JavaScript contains no credential harvesting, network requests, or exfiltration logic., The binary is started only when the user invokes \`codex\`. ## Public findings ### 1.
