MAL-2026-10290 Malicious code in backupgenuine-updated (npm)

Package published as [email protected] with description "Republished package" actually contains a Vite-built single-page application titled "Lucide" that implements a Scramjet in-browser web proxy (JS/WASM assets under bfjdx/ and ct1tl/, service worker, boot module). package.json declares no lifecycle scripts (no preinstall/install/postinstall/prepare) and main points to index.html, so npm install and require() do not execute any of the shipped code on the installing machine. The shipped index.html injects a third-party script from https://c.vipersfutbol.com/script.js and the boot module hardcodes wss://21baseballacademy.com/fairs/ as the proxy transport; both only run in a browser that serves and loads the built SPA, not on the developer installing the tarball. Several bundled route chunks (AccountPage, DarkVeil, GamesPage, PlusBlockedNote, SettingsPage) are heavily obfuscated with hex-identifier naming, which is a transparency concern for the browser-side application but does not create an install-time or import-time code path on the installer.

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.
