If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3.

The script collects the installer's hostname, username, current working directory, network interface IPs/MACs, OS info, the presence of env vars including credential-shaped names (APP_KEY/APP_SECRET/etc.), and the full process list (`ps aux` on Unix, `tasklist /V` on Windows), then HTTP POSTs the JSON payload to a hardcoded Burp Collaborator endpoint at http://dduqpvg687wohv3ymaiaa3j2etks8swh.oastify.com (with a secondary reference to http://your-id.burpcollaborator.net). The package self-labels via `X-PoC-Type: dependency-confusion` / `X-PoC-Package: ttspc-server-sample` headers and uses an inflated 99.9.0 version designed to win semver resolution against a victim org's private internal package of the same name. Even framed as a PoC, the install-time exfiltration of host identifiers, internal IP addresses, credential-variable names, and running process inventory to an attacker-controlled OAST host is a real supply-chain attack against any installer that resolves this public package instead of the intended private one.\n\nAny 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.
