devplatform-eslint-plugin-nx@35.6.5 is a typosquat lure targeting @nx/eslint-plugin. On require() of the package, index.js loads runtime.js which asynchronously downloads a per-platform binary from one of three obfuscated Cloudflare Workers hosts (oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev), with a DNS-TXT chunked-base64 fallback across sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru. The payload is written to /tmp or %TEMP% under a disguised name (dotnetdiag<suffix>.exe on Windows,.cache<suffix> on Unix), chmod 0755'd on non-Windows, and detached-spawned via /bin/sh -c or cmd.exe /c start. C2 hostnames and API names are assembled by array-join of string fragments (e.g. ["oob-worker.cf101","-adf.worker","s.d","ev"].join("") and fs["chmod"+"Sync"]) to evade static detection. A telemetry cover story (opt-out checks for DISABLETELEMETRY / ANALYTICSOPTOUT / DONOTTRACK, a cooldown stamp at /tmp/.analyticsstate) is layered over the dropper. A second, currently unreferenced but shipped bundle lib/telemetry.js contains the same dropper primitives.
