That code transmits the machine hostname to an external endpoint. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-08-28T12:06:45.838Z - **Finished:** 2026-08-28T12:07:12.133Z - **Download time:** 504 ms - **Static scan time:** 10 ms - **AI review time:** 25781 ms - **Total time:** 26295 ms ## Security analysis ### Published attack-surface review - **Summary:** Installing the package automatically executes code before and after installation. That code transmits the machine hostname to an external endpoint. - **Trigger:** npm installation, including dependency installation, triggers preinstall and postinstall. - **Impact:** It leaks an installation-environment identifier without a user action and can track affected hosts. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-08-28T12:07:12.133Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Install-time hostname exfiltration over HTTPS. - **Attack narrative:** The package configures npm preinstall and postinstall hooks to run index.js. The script obtains the host name and includes it in a request to a Pipedream-controlled URL. This occurs automatically during installation. A self-dependency on cacao1 also creates unnecessary lifecycle supply-chain risk. - **Rationale:** Source inspection confirms unconsented install-time transmission of the host name to an external collection endpoint. The automatic hooks and self-dependency increase the supply-chain risk. - **Files touched:** package.json, index.js - **Network endpoints:** eo8f3m3ho26a0nm.m.pipedream.net ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** Both preinstall and postinstall automatically run index.js during npm installation., The lifecycle code sends the installing machine's hostname to an external Pipedream endpoint., The package declares a runtime dependency on its own package name and compatible release range. - **Evidence against:** The inspected source does not show file reads, credential harvesting, or destructive writes., The source is short and does not contain an additional downloaded payload or shell execution. ## Public findings ### 1.
