MAL-2026-10528

Summary: Malicious code in @vitets/vite-ts (npm)

Details: Source: amazon-inspector (8fe093d0d0fa83ab20aa57e9d9c8500e03a25ead578ff351fdc3609118cf5ecf) Package is published as `@vitets/vite-ts` and copies the legitimate Vite project's author (`Evan You`), README, homepage (`vitejs.dev`), and repository (`github.com/vitejs/vite`) to impersonate the real `vite` / `@vitejs/*` packages, and declares a `bin` entry named `vite` so consumers who install it and run the `vite` CLI execute the package's `bin/vite.js`. After ~5KB of whitespace padding, `bin/vite.js` contains an obfuscated payload that uses a custom string-scramble routine to hide identifiers (`require`, `child_process`, `spawn`, `eval`, hostnames, HTTP/JSON-RPC method names) as numeric indices into a reconstructed string table, defeating static IOC scanning. The decoded routine performs an HTTPS GET and a JSON-RPC POST to remote hosts, XORs the response with a key fetched from a second endpoint, runs `eval(r)` on the result, and additionally `child_process.spawn`s a detached background process to execute it (with `detached:true`, `windowsHide:true`). This gives the publisher arbitrary code execution on the developer's machine every time the `vite` CLI is invoked, with no integrity check on the fetched code. The package's `dist/` bundle also contains base64+Buffer decode primitives consistent with additional obfuscated payload handling. Source: ghsa-malware (e6fa8ee8ed2a92db620d30015fe7d672d1dd66e500b3749a71cfd1486d62ca4d) 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.
