Malicious code in twork-data-services-invest-box-account (npm)

On module load, index.js requires./_adapter.js which detects OS/architecture, fetches an opaque binary via https.get from string-concatenated Cloudflare Workers hostnames (oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.workers.dev) and, on failure, reconstructs the payload from base64-encoded DNS TXT records under well1.site subdomains (tin/tina/ldr/win.dl.well1.site). The fetched bytes are written to /tmp or %TEMP% under masquerading names such as dotnet_diag_* and.cache_*, chmod 755'd on Unix, and spawned detached via spawn('/bin/sh', ['-c', path+' &']) or cmd.exe /c start /b on Windows. Hostnames are assembled via Array.join('') splits to defeat plain-string scanners. No hash or signature verification is performed, no publisher-matched host is used, and the delivered bytes are opaque. The package presents itself as a telemetry/analytics helper.
