On require() of the package, index.js loads _init.js which reconstructs attacker-controlled hostnames via array-join string obfuscation (four oob-worker.cf*.workers.dev hosts plus a DNS-TXT base64 fallback under *.dl.well1.site), downloads a platform-specific native binary, writes it to /var/tmp or %TEMP% under deceptive names such as.cache_<hex> or dotnet_diag_<hex>.exe, chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start /b. A second, parallel downloader-and-launcher wrapped in a fake 'Analytics SDK' cover story is shipped in lib/telemetry.js (ServiceDiscovery over DNS, WorkerHost spawning /bin/sh with base64-decoded chunks). Endpoint hostnames, sensitive API names (chmod+Sync, require('child_'+'process'), _p('platform')) are reconstructed at runtime to evade static inspection. Require()ing the package yields arbitrary attacker code execution on the installer host.

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.
