Which versions of react-vite-assert are malicious?

The following npm versions of react-vite-assert are flagged malicious: 1.4.1. Treat any of these as compromised.

How do I remediate react-vite-assert if I installed it?

Remove react-vite-assert from your project and lockfile, then assume any secrets accessible to the build or runtime were exposed: rotate API keys, tokens, and credentials, and audit for unexpected outbound network activity or persistence. Use O3 Security's dependency scanner to confirm the package and its artifacts are fully purged across your stack.

Is react-vite-assert part of a known attack campaign?

Yes — react-vite-assert is associated with the IN-MAL-2026-006845 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

Can O3 Security detect react-vite-assert in my codebase?

Yes. O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, blocking react-vite-assert and packages like it before any post-install script runs.

What this malware does

[email protected] executes attacker-controlled JavaScript whenever the package is imported. The main entry transitively loads src/features/extras/config.js, which runs a top-level async IIFE that issues an HTTPS GET to https://www.jsonkeeper.com/b/HXDNM, takes the data.config string from the response, wraps it with new Function('require', s), and invokes it with a createRequire(import.meta.url)-built require — granting the fetched code full Node.js access (filesystem, network, child_process, env). The fetch is retried up to 5 times. The remote URL and request headers are disguised by a fake local process shadow object whose keys are named DEV_API_KEY/DEV_SECRET_KEY/DEV_SECRET_VALUE, where DEV_API_KEY actually holds the paste URL and the other two hold a request header name/value — deliberate misdirection rather than configuration. jsonkeeper.com is an anonymous, mutable paste host: whoever controls /b/HXDNM can change the executed payload at any time without republishing the package. The combination of import-time auto-execution, anonymous mutable code source, eval of fetched bytes with full require, and cover-story variable naming is unambiguous supply-chain attack tradecraft.
