MAL-2026-10619 Malicious code in @vite-js/vui (npm)

Package publishes under @vite-js/vui while impersonating the official vite package: package.json sets author "Evan You", description "Native-ESM powered web dev build tool", repository github.com/vitejs/vite.git, and bin name "vite" mapped to bin/vite.js. bin/vite.js is the legitimate Vite bootstrapper with an obfuscated trailer appended after the normal start() call: a shuffle-decoder resolves the string "constructor" (var XVL=Oto[Ywu]), builds a Function from a decoded opaque source blob, and immediately invokes it (var CpK=XVL(HuO,Oto(IHO)); var ARH=CpK(Oto('…')); var hTf=plc(byk,ARH); hTf(3504);). Every invocation of the vite command (npm run dev/build/preview, npx vite) executes the hidden author-supplied code on the developer's machine. devDependencies additionally include @solana/web3.js, axios, socket.io-client, and form-data — libraries consistent with wallet-drainer / C2 exfiltration functionality and not present in upstream Vite.

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.
