Malicious code in ded-aa-liza-ui-components (npm)

On require() of this package, index.js loads _helpers.js which downloads a per-platform native executable (linux_x64, linux_arm64, darwin, win32) from attacker-controlled Cloudflare *.workers.dev endpoints (oob-worker.cf100-416.workers.dev, cf101-adf.workers.dev, cf99-9b3.workers.dev) with a DNS-TXT base64 fallback under *.dl.wel1.ru (sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru). The downloaded bytes are written to /var/tmp or %TEMP% under disguised names (.cache_<hex> on Unix, dotnet_diag_<hex>.exe on Windows), chmod 0755, and spawned detached via spawn("/bin/sh", ["-c", fp+" &"], {detached:true}) or spawn("cmd",...). Destination hostnames are reconstructed at runtime by splitting/joining string fragments (e.g. ["oob-worker.cf101-adf",".workers.d","ev"].join("")) to evade static analysis. Comments and env-var checks (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) mimic telemetry as cover. The advertised purpose is a React UI components library, which does not require fetching and executing native binaries from third-party Cloudflare Workers infrastructure.
