Summary
Malicious code in boxy-maker-wave (npm)
Details

-= Per source details. Do not edit below this line.=-

On require() of the package, index.js loads platform.js which selects a platform-specific endpoint, downloads an opaque binary over HTTPS from Cloudflare Workers hosts assembled via string-array joins (oob-worker.cf101-adf.workers.dev family) with a DNS-TXT fallback channel that resolves TXT records under sdk.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru / ext.dl.wel1.ru, reassembles base64 chunks into an executable, writes the file under a disguised name (dotnetdiag_*.exe /.cache_* /.analyticsstate) in a temp directory, chmods it 0755, and detached-spawns it via spawn("/bin/sh", ["-c", fp+" &"], {detached:true}).unref() (or spawn("cmd",...) on Windows). Destination hostnames are hidden from static scanners by array.join string concatenation, and the code is decorated with cover-story comments ("Cache validation", "Parallel DNS resolution") and telemetry-shaped env gates (DISABLETELEMETRY / ANALYTICSOPTOUT / DONOTTRACK) to masquerade as analytics. No hash/signature check on the fetched bytes; the hosts have no relationship to any publisher.
