The script hides its console window and moves it off-screen via SetWindowPos, concatenates roughly 150 base64 chunks, XOR-decodes them, and passes the resulting bytes to System.Reflection.Assembly.Load().Invoke — an in-memory.NET assembly loader characteristic of RAT/stealer stagers. The package has no index.js, no main entry, and no lifecycle scripts, so `npm install` and `require()` do not themselves run the loader; the package exists purely to deliver and disguise the staged PowerShell/.NET payload for later execution on the host.\n\n## Source: ghsa-malware (698338a866ac3c7c579c999f0c37c7aa2508fef1ffe1d1679d83e71d79fc0145)\nAny computer that has this package installed or running should be considered fully compromised.
