That file embeds ~60KB of base64 chunks under `MANIFEST_CACHE_SEED` and a custom `decodeManifestSeed` routine that XOR-unmasks the bytes with 0x5a and `zlib.gunzipSync`s the result. When the file runs as main (`require.main === module`), the decoded string is passed to `new Function(decodeManifestSeed())(__filename, [...])`, yielding arbitrary code execution on every `npm install` with no signature, no network pin, and no human-readable payload. The shipped source map's `sourcesContent` for manifest-cache.js ends at a benign `ManifestCacheReader` class and does not contain the top-level `require.main === module` dispatcher that appears in the compiled JS, indicating the source map was scrubbed to hide the loader from source-level review. The dropper is also reachable at runtime through the package's public API: `dist/index.js` re-exports `./project`, which re-exports `./manifest-cache`, and `ManifestCacheReader.warm()` spawns a detached `node __filename --warm` subprocess that re-enters the main-mode decode-and-eval branch outside the parent process lifecycle.\n\n## Source: ghsa-malware (f61412a3cec35a73a5b37775eec9289fff4eaca86da7ae85060fb9f6989ab2a8)\nAny computer that has this package installed or running should be considered fully compromised.
