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, dotnet_diag.exe,.analytics_state), 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 (DISABLE_TELEMETRY / DO_NOT_TRACK opt-outs,.analytics_state cache) is used as cover. Fires on any require()/import of the package, including transitively.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
