If validation fails on a non-localhost site, it empties the host application's body. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 98.0% - **Started:** 2026-09-05T04:28:55.194Z - **Finished:** 2026-09-05T04:29:44.988Z - **Download time:** 261 ms - **Static scan time:** 88 ms - **AI review time:** 49444 ms - **Total time:** 49794 ms ## Security analysis ### Published attack-surface review - **Summary:** Rendering the component triggers remote license validation. If validation fails on a non-localhost site, it empties the host application's body. - **Trigger:** A consumer mounts Reaction with an invalid, expired, revoked, or unavailable license result. - **Impact:** It can destroy the visible content and operation of the consumer's web application. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-05T04:29:44.988Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated license gate that replaces the document body. - **Attack narrative:** The package performs a license check when Reaction is mounted. On a non-localhost host, an invalid result causes it to create an empty body and replace the application's existing body. This is unrelated to rendering flying emoji and is hidden in an obfuscated bundle; it can take down any page using the component. - **Rationale:** The component contains a concrete, destructive action against the consuming application's DOM, guarded only by remote-controlled license status. No install hook is needed for this harmful runtime behavior. - **Files touched:** index.js, document.documentElement, document.body - **Network endpoints:** https://api.npoint.io/f63d2269d3d045f8cdc3 ### Review decision - **Verdict:** Malicious - **Confidence:** 98.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The obfuscated component replaces the consumer page body with a new empty body after a failed license check outside localhost., Mounting the component automatically verifies a license and can fetch a remote revocation list., The published entry point is deliberately obfuscated, concealing this destructive browser behavior. - **Evidence against:** package.json has no install lifecycle scripts and declares only React as a peer dependency., The inspected code contains no child-process, shell, filesystem, or credential-exfiltration behavior. ## Public findings ### 1.
