Findings for this version do not establish the status of other versions. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Installation automatically collects host and user information and sends it to a fixed external webhook. The same behavior executes when the entrypoint is imported. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 99.0% - **Started:** 2026-10-01T17:57:34.655Z - **Finished:** 2026-10-01T17:58:14.320Z - **Download time:** 770 ms - **Static scan time:** 10 ms - **AI review time:** 38885 ms - **Total time:** 39665 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installation automatically collects host and user information and sends it to a fixed external webhook. The same behavior executes when the entrypoint is imported. - **Trigger:** npm postinstall execution or importing index.js. - **Impact:** Exposes identifying host, user, network, and environment metadata to the webhook recipient. - **Evidence paths:** package.json, index.js - **Review source:** ai\_review - **Reviewed:** 2026-10-01T17:58:14.320Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint serializes system information and environment variable names, then transmits the payload through an HTTPS POST without a consent gate. - **Attack narrative:** The postinstall hook launches index.js automatically. It gathers system and user information, local network addresses, and environment variable names, then posts that information to a fixed external webhook. No explicit opt-in or destination validation gates the transmission. - **Rationale:** The inspected source establishes automatic data exfiltration during installation. The security research label does not neutralize the active collection and transmission behavior. - **Network endpoints:** https://webhook.site/4f227930-968e-4511-9769-ff85c43164b7 ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** package.json automatically runs index.js after installation., index.js collects hostname, operating system details, user information, local network addresses, and environment variable names., index.js targets a fixed webhook.site endpoint with an HTTPS POST., index.js sends the collected payload immediately and suppresses request errors. - **Evidence against:** The payload collects environment variable names, not their values; no credential theft is demonstrated. ## Affected versions and remediation This report applies to hyperion-react-native-testapp@999.0.1. - Avoid installing hyperion-react-native-testapp@999.0.1. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
