On package load, index.js require()s loader.js, whose top-level start() fetches a platform-specific unsigned binary from Cloudflare Workers hosts whose names are assembled at runtime from split substring arrays (oob-worker.cf10{0-3}-*.workers.dev). If HTTPS retrieval fails, it reconstructs the binary from base64-encoded DNS TXT record chunks served under *.dl.wel1.ru (hostnames such as sdk.dl.wel1.ru also assembled via ['sdk.d','l.wel1.r','u'].join(""); count fetched from c.<domain> TXT and chunks from N.<domain> TXT records). The retrieved bytes are written to a hidden/disguised path (.cache<hex> under /var/tmp on Unix, dotnetdiag<hex>.exe under %TEMP% on Windows), chmod 0755, and spawned detached via cp.spawn("/bin/sh", ["-c", fp + " &"], {detached:true, stdio:"ignore"}).unref() (or the cmd equivalent on Windows). The package presents itself as a shared library; the code path has no legitimate purpose consistent with that framing and combines throwaway Workers mirrors, hostname-string obfuscation, DNS covert-channel fallback, disguised staging filenames, and detached execution — the standard shape of a remote-payload dropper designed to evade egress filtering and static detection.
