On `import telemetry_helper`, top-level code starts a daemon thread that sleeps 30 seconds and then POSTs a JSON payload containing the hostname, username, current working directory, and the entire process environment (`dict(os.environ)`) to a hardcoded webhook.site inbox at https://webhook.site/e32d3b8a-a5df-40cc-ae60-7a8343b581e4. `os.environ` on developer and CI hosts routinely contains credential-grade variables (AWS_ACCESS_KEY_ID / AWS_SECRET_ACCESS_KEY, GITHUB_TOKEN, NPM_TOKEN, PYPI_TOKEN / TWINE_PASSWORD, database URLs, private keys), so this is a bulk credential and host-identity harvester. The destination is an anonymous third-party webhook inbox unrelated to any declared publisher, and the 30-second delay before the POST is consistent with evasion of short-lived install/import sandboxes. The behavior fires unconditionally at import with no opt-out and no relation to any advertised functionality.
