GitHub repository carrying the DPRK-linked PolinRider malware kit: obfuscated JavaScript disguised as a font/build-config file (compiler/packages/babel-plugin-react-compiler/src/__tests__/fixtures/compiler/inner-function/nullable-objects/assume-invoked/public/fonts/fa-brand-400.woff) that executes with Node when the project is opened or built, delivering a backdoor/infostealer chain. Malicious payload found in: compiler/packages/babel-plugin-react-compiler/src/__tests__/fixtures/compiler/inner-function/nullable-objects/assume-invoked/public/fonts/fa-brand-400.woff Commit: a2e5ebfddd8872c613d0e6d12f880a830740eb48 Marker: none in plaintext (variant wraps the blob as (function(...){...}(global,require))) Execution trigger: .vscode/tasks.json hidden "eslint-check" shell task with runOn: folderOpen, hide: true, reveal: never — runs `node ./compiler/packages/babel-plugin-react-compiler/src/__tests__/fixtures/compiler/inner-function/nullable-objects/assume-invoked/public/fonts/fa-brand-400.woff` silently when the folder is opened in VS Code/Cursor. Payload: single-line javascript-obfuscator blob in a fake Font Awesome file, padded with leading whitespace so it renders blank in editors. PolinRider v5 kit (DPRK-attributed); same tasks.json + fake-font layout documented by JFrog Security Research (2026-06-24). Staged fork of react/react (never submitted as a PR). Found by account fork sweep.
