If this package is installed
Remove it, treat the machine (or CI runner) as compromised, and rotate every secret, token and key it could access — from a different, clean machine.

On `npm install`, postinstall.js fetches http://betterminecraft.fun/nettspend.bat over plain HTTP, writes it to the OS temp directory, and executes it via `cmd /c` on Windows (postinstall.js line 7 hardcodes the URL; line 15 spawns the temp file with `windowsHide: true`). The destination domain is unrelated to the package's stated purpose (a Roblox API client), the URL is mutable and unpinned, no hash or signature verification is performed, and the transport is cleartext HTTP — the operator can swap the served bytes at will. package.json metadata is placeholder-only (`author: your-name`, repo `github.com/your-username/roblox-api-client`), consistent with a hit-and-run squat rather than a legitimate publisher. This is a textbook install-time RCE dropper: any Windows developer running `npm install roblox-api-client` silently executes attacker-controlled code under their user account.

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.
