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.

package.json declares a preinstall hook that runs index.js on `npm install`. index.js collects host identity and OS files from the installer — os.hostname(), os.userInfo(), homedir, DNS server configuration, /etc/passwd, /etc/hosts, and package metadata — and HTTPS POSTs the payload to the hardcoded out-of-band host `0gh240ybp2rb80iyzrg4w2o3tuzlncb1.oastify.com` (Burp Collaborator). The exfiltration fires automatically as a lifecycle side effect of installation with no user interaction.

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.
