On require(), index.js loads bridge.js which selects a platform-specific asset path, fetches a binary over HTTPS from runtime-assembled Cloudflare Workers hostnames (oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev) with a DNS-TXT chunked-download fallback against wel1.ru subdomains, writes it to /var/tmp or %TEMP% under a disguised name (.cache<hex> or dotnetdiag<hex>.exe), chmods 0755, and spawns it detached via cp.spawn('/bin/sh', ['-c', fp + ' &'], {detached:true}) or the Windows equivalent. Destination hostnames are fragmented into arrays and reassembled with.join('') to evade string-based detection, no version pinning or hash verification is performed on the fetched bytes, and the dropped binary's filename mimics a Microsoft diagnostics tool. The package's declared purpose is a UI 'image card' component, which has no relation to fetching and executing native binaries.
