A global npm install automatically downloads and executes a remote shell installer, then adds a marketplace and plugin to Codex. These changes occur before the user invokes the package CLI. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-09-04T07:52:52.207Z - **Finished:** 2026-09-04T07:53:54.922Z - **Download time:** 759 ms - **Static scan time:** 808 ms - **AI review time:** 61146 ms - **Total time:** 62715 ms ## Security analysis ### Published attack-surface review - **Summary:** A global npm install automatically downloads and executes a remote shell installer, then adds a marketplace and plugin to Codex. These changes occur before the user invokes the package CLI. - **Trigger:** npm install -g @essentialai/cogent-bridge - **Impact:** Modifies the user's Codex installation and agent extension configuration without a separate confirmation. - **Evidence paths:** package.json, scripts/postinstall-global.mjs - **Review source:** ai\_review - **Reviewed:** 2026-09-04T07:53:54.922Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** postinstall remote shell execution and Codex plugin installation - **Attack narrative:** The package declares a postinstall hook. During a global npm installation, it invokes a curl-to-shell command to install a managed Codex build and then adds a GitHub marketplace and installs the cogent@cogent plugin through the Codex CLI. The hook suppresses installation failure by exiting zero. This is an unconsented lifecycle mutation of a broad AI-agent control surface. - **Rationale:** The automatic postinstall performs remote shell execution and changes Codex plugin configuration during installation. Its global-install guard limits exposure but does not establish consent for these agent-control changes. - **Files touched:** ~/.codex/packages/standalone, Codex plugin marketplace configuration - **Network endpoints:** chatgpt.com, github.com ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The manifest automatically runs a postinstall script., On global installation, the hook downloads a remote installer and pipes it to a shell., The hook modifies the Codex control surface by adding a Git marketplace and installing a plugin., The hook deliberately exits successfully even if setup fails. - **Evidence against:** The hook is guarded to run only for global npm installs and skips CI and Windows., The inspected lifecycle code did not harvest credentials or exfiltrate local data. ## Public findings ### 1.
