It may contact a third-party revocation endpoint and uses browser properties to control whether the component renders. - **Trigger:** A React application mounts the default Reaction component. - **Impact:** Applications may make an undisclosed third-party request and have rendering controlled by opaque code; no direct data exfiltration was confirmed. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T10:42:28.983Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated browser fingerprinting and remote license-revocation checking. - **Rationale:** No install-time execution or confirmed exfiltration was found, so the evidence does not support a malicious verdict. The concealed remote licensing and fingerprint-derived render gate are not aligned with the stated component and warrant a warning. - **Files touched:** index.js - **Network endpoints:** https://api.npoint.io/f63d2269d3d045f8cdc3 ### Review decision - **Verdict:** Suspicious - **Confidence:** 89.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Low - **Evidence for:** The runtime entry is a deliberately obfuscated single-line bundle that hides its actual browser behavior., On component mount, hidden license code fetches a revocation list from a third-party endpoint., The code builds a browser-derived identifier from navigator properties and uses it to gate rendering., The README describes an emoji animation but does not disclose the license verification, network request, or browser fingerprinting. - **Evidence against:** package.json has no preinstall, install, postinstall, or other lifecycle script., The network request fetches a shared revocation list; the inspected call does not send the license ID or browser identifier., No child-process, filesystem, shell, eval, or dynamic-code execution was found in the shipped entry. ## Public findings ### 1.
