Destination hostnames are assembled from split string fragments joined at runtime to evade static URL scanners. When HTTPS fetches fail, the loader falls back to base64-encoded chunks retrieved from DNS TXT records under attacker-controlled subdomains of dl.well1.site (tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site), reassembling and executing the payload from the encoded chunks. A second file lib/telemetry.js shipped in the tarball contains a matching download-decode-chmod-spawn class with the same operator shape.

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.
