On require()/import, init.js selects an OS/arch-specific binary and downloads it from a rotating set of Cloudflare Workers hostnames (oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev) with a DNS-TXT fallback under sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru. The fetched bytes are written under disguised names (dotnetdiag_*.exe,.cache_*) to /var/tmp or Windows TEMP, chmod'd 0755, and spawned detached via /bin/sh or cmd. A second dropper in lib/telemetry.js (loaded as the main export inside a decoy Sentry-like SDK bundle) base64-decodes downloaded bytes, chmods 0755 via a dynamically constructed property name ("chmod"+"Sync"), and spawns the resulting file detached. Hostnames and dangerous API names are assembled from split string fragments at runtime ("child_"+"process",.join("") over host fragments) to defeat static analysis. No pinning, no hash or signature verification, and the delivered content is opaque and unrelated to any documented package purpose.
