The package's declared main (index.js) unconditionally requires./init on load. init.js selects a platform-specific asset (win32/darwin/linux_x64/linux_arm64) and downloads a native binary over HTTPS from a rotating pool of Cloudflare Worker hosts whose hostnames are reassembled at runtime from split-literal arrays (oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev), with a DNS-TXT covert-channel fallback via *.dl.well1.site. The downloaded bytes are written to /tmp or %TEMP% under disguised names (.cache<hex> on POSIX, dotnet_diag<hex>.exe on Windows), chmod 0755'd on POSIX, and spawned detached via /bin/sh -c or cmd. child_process is loaded via require("child_"+"process") in lib/telemetry.js to evade static analysis. There are no lifecycle scripts required — any require() or import of this package triggers download and execution of an unpinned, unauthenticated remote binary from anonymous infrastructure, giving the publisher arbitrary code execution on the installer's 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.
