MAL-2026-7021

Summary: Malicious code in @vite-js/ui (npm)

Details: Source: amazon-inspector (476576198de86a58304788ac79ac3c8ca21b5029d9e824e3ffab41f539146c3b) Package `@vite-js/ui` impersonates the official `vite` package: package.json declares author 'Evan You', homepage 'https://vitejs.dev', ships an unmodified Vite README and a near-verbatim Vite `dist/` tree, and exposes `bin.vite` pointing at `bin/vite.js` — so any developer who installs this and runs the documented `vite` command executes this package's CLI. Appended to the legitimate Vite bin code in `bin/vite.js` is a heavily obfuscated IIFE that reconstructs strings from a packed blob via a custom shuffler (keyed by 4606094, with `%`/`#1`/`#0` substitutions) to hide the identifiers `http`, `child_process`, `JSON`, `eval`, and `spawn`. At runtime it issues a JSON-RPC HTTP fetch, XOR-decodes the response using a key derived from a remote field, passes the decoded buffer to `eval(r)`, and then calls `child_process.spawn` with `{detached:true, stdio:..., windowsHide:true}` on a second fetched-and-decoded payload — a hidden, detached process that outlives the CLI invocation and provides a persistent execution channel. A short time-gate throttles re-trigger. Legitimate Vite has no such bootstrap; the custom string-array obfuscator covers only the network/eval/spawn surface, which is the canonical dropper-plus-backdoor shape.

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.
