pfp-forms-sme-sitebuilder@20.2.1

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.
