On require of the package (index.js loads./_vendor at import), _vendor.js selects a platform-specific staging path, downloads a binary from a rotated list of Cloudflare workers.dev origins whose hostnames are reconstructed at runtime from split-string arrays joined together, with a DNS TXT covert-channel fallback that reassembles base64 chunks from numbered subdomains under dl.well1.site. The fetched bytes are written to /var/tmp or %TEMP% under cover-story filenames (.cache_<rand>, dotnet_diag_<rand>.exe,.analytics_state), chmod 0755, and spawned detached via /bin/sh -c or cmd.exe /c start. No hash or signature verification is performed and destinations are not first-party publisher infrastructure. Any consumer that imports this package auto-executes an attacker-controlled native payload on the installer's host.
