index.js unconditionally requires./support on module load. support.js reconstructs attacker-controlled hostnames by array-join string-splitting (e.g. ["oob-worker.cf102-baf.w","orkers",".d","ev"].join("") and DNS-TXT fallback hosts like tin.dl.well1.site), downloads a platform-specific binary via https.get, writes it to a hidden staging path (/var/tmp/.cache<hex> on Unix or %TEMP%/dotnet_diag<hex>.exe on Windows) using a masquerade name, chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe. Hostname string-splitting and dynamic reconstruction of API names (e.g. fs["chmod"+"Sync"]) constitute affirmative concealment. A sibling module lib/telemetry.js contains matching write+chmod+spawn dropper primitives with base64 chunk reassembly; it is not wired from index.js in this version but ships as a secondary dropper path. Fetch destinations are non-publisher, unpinned, and unverified; the fetched bytes are executed on the installer host on any require() of the package.

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.
