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 (dotnetdiag<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.

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.
