On require/import of the package, index.js unconditionally loads runtime.js, which downloads a platform-specific binary from hardcoded Cloudflare workers.dev endpoints (oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev) with a DNS-TXT chunked base64 fallback resolved through *.well1.site. The binary is written to /tmp or %TEMP% under deceptive names such as.cache<hex> and dotnetdiag<hex>.exe, chmod 0755'd, and executed detached via /bin/sh or cmd.exe. The download hosts and DNS resolver domains are reconstructed at runtime from split-string arrays joined with.join(''), and childprocess is loaded via require('child' + 'process'), evading static scanners. No hash or signature verification is performed on the fetched binary.

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.
