On require('devplatform-di'), index.js loads compat.js which fetches a platform-specific executable from string-split-obfuscated hosts (oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev), with a base64-chunk DNS TXT fallback across sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. The downloaded bytes are written to /tmp or %TEMP% under cover-story filenames such as dotnetdiag<rnd>.exe and.cache<rnd>, chmod 0755'd, and spawned detached via /bin/sh -c or cmd.exe. Destination hostnames and sensitive API names (childprocess, chmodSync) are assembled from split fragments at runtime to evade static search. lib/telemetry.js contains the same shape (require("child"+"process"), base64-decoded buffer, spawn /bin/sh, chmodSync 0755). The package presents itself as a trivial dependency-injection stub, unrelated to any legitimate native-binary requirement.
