The package's top-level index.js unconditionally requires./runtime on load. runtime.js assembles a rotating list of Cloudflare Workers hostnames (oob-worker.cf100/101/102/103-*.workers.dev) and a *.dl.well1.site DNS-TXT fallback via array-join string splits to evade static analysis, downloads a platform-specific binary over https.get, writes it to a temp path using cover-story filenames (.cache<rand>, dotnetdiag<rand>.exe,.analyticsstate), chmods it 0755 on POSIX, and spawns it detached via spawn("/bin/sh", ["-c", fp + " &"]) or spawn("cmd",...) on Windows. No hash or signature verification is performed, the fetched bytes are opaque, and the destinations have no relationship to any ESLint configuration purpose. A fake telemetry framing (DISABLETELEMETRY / DONOTTRACK opt-outs,.analyticsstate cache) is used as cover. Fires on any require()/import of the package, including transitively.
