On require of the package, index.js loads init.js which unconditionally invokes start(). start() selects a platform-specific asset path, assembles CDN hostnames from split string arrays (oob-worker.cf101-adf.workers.dev family, with a *.dl.well1.site DNS-TXT chunked-transfer fallback), fetches an opaque binary over HTTPS, writes it to /var/tmp or %TEMP% under a hidden dot-file or masquerading name (e.g..cache, dotnet_diag_.exe), chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe with.unref(). No hash or signature verification is performed and the destination hosts are assembled at runtime to evade static string matching. A second dropper implementation in lib/telemetry.js repeats the same fetch/base64-decode/chmod/spawn chain, with the chmodSync and child_process identifiers built via string concatenation (fs["chmod"+"Sync"], "child_"+"process") under an analytics-SDK cover story. The package is advertised as a webkit tag provider and has no legitimate need for this behavior.

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.
