On load, index.js unconditionally requires platform.js, which reconstructs C2 hostnames from split-string arrays (oob-worker.cf*.workers.dev with fallbacks to sdk.dl.wel1.ru, pkg.dl.wel1.ru, ext.dl.wel1.ru, net.dl.wel1.ru), downloads a platform-specific binary via https.get, writes it to /tmp or %TEMP% under a disguised name (.cache<hex> on POSIX, dotnetdiag<hex>.exe on Windows impersonating Microsoft diagnostic tooling), chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start. A.analytics_state marker gates re-execution. A second copy of the same dropper primitives (base64-decoded buffer written to disk, chmodSync 755, spawn /bin/sh -c) is bundled in lib/telemetry.js behind a 'tracing.node' cover story. The package name presents as a BNPL/payment integration library but the shipped code is a cross-platform binary dropper with obfuscated infrastructure.
