On require of the package, _init.js (unconditionally loaded from index.js) fetches a platform-specific executable from one of three obfuscated Cloudflare Workers hosts (oob-worker.cf101-adf.workers.dev, cf102-baf.workers.dev, cf103-070.workers.dev), with a base64-over-DNS-TXT fallback via tin.dl.well1.site. The C2 hostnames are runtime-assembled from split string arrays to evade static inspection. The fetched binary is written to a disguised temp path (dotnet_diag_<rand>.exe on Windows or.cache_<rand> on POSIX), chmod 0755, and spawned detached via /bin/sh -c '<path> &' or cmd.exe /c start /b, with a /tmp lock file gating re-execution. A second, currently-unreferenced dropper is also bundled at lib/telemetry.js under an 'analytics SDK' cover story, using string-concat require('child_'+'process') and the same fetch-write-chmod-spawn shape with a base64-chunked embedded buffer.
