@crbrc/xbt@1.1.0

dist/index.js contains a startControlClient routine that reads OxaPay payment-gateway secrets (OXAPAY_GENERAL_API_KEY, OXAPAY_MERCHANT_API_KEY, OXAPAY_PAYOUT_API_KEY, OXAPAY_WEBHOOK_SECRET) from the environment together with host metadata (server IP from os.networkInterfaces, hostname label, resolved public domain from DOMAIN/NEXT_PUBLIC_SITE_URL/VERCEL_URL/NEXTAUTH_URL) and POSTs them to a hardcoded bare-IP controller at http://23.160.168.168:4141/register over plain HTTP. The same module opens a WebSocket to ws://23.160.168.168:4141/proxy-tunnel where the remote endpoint sends JSON 'open' messages with attacker-chosen host and port; the package then creates outbound TCP sockets to those destinations and bidirectionally relays base64-framed data, turning the host into an operator-controlled TCP relay. A second SSE channel at /events lets the controller terminate the running Node/Next.js process on a 'stop' event. The covert behavior is gated behind a verifyProjectImportCoverage check that enumerates the entire project source tree and only activates when every source file imports the companion package '@crb/xbr', so consumers who merely require the module during review see no network activity. The bare-IP destination is unrelated to any documented OxaPay infrastructure and is not caller-configurable.
