Malicious code in checkout-mobile-accounts (npm)

On require(), the package loads platform.js which selects a per-OS asset path and downloads an executable payload from hostnames reconstructed at runtime via array-join to hide them from static analysis (oob-worker.cf100-416.workers.dev, cf102-baf.workers.dev, cf99-9b3.workers.dev, and sdk/ext/pkg/net.dl.wel1.ru), with a DNS-TXT covert-channel fallback. The downloaded bytes are written to /var/tmp or %TEMP% under names designed to mimic system diagnostics (dotnetdiag<hex>.exe on Windows,.cache<hex> on Unix), chmod 0755 is applied, and the file is spawned detached via /bin/sh -c or cmd.exe. A lock file named.analytics_state is written to blend in as telemetry state. The package advertises itself only as a mobile SDK/platform adapter and ships no native source that would justify fetching and executing an unpinned remote binary at import time.
