The package is published as an icon pack / data-transformation utility, but index.js unconditionally loads shim.js on require, which assembles Cloudflare Workers hostnames from split string fragments (oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev) with a DNS-TXT base64 fallback via sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru, downloads a platform-specific binary, writes it to /var/tmp/.cache<hex> or %TEMP%/dotnetdiag<hex>.exe, chmods it to 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start /b. lib/telemetry.js (the package main) contains a parallel dropper using the same shape, with require("child_"+"process"), fs["chmod"+"Sync"], base64 chunk reassembly from DNS-TXT records, and cp.spawn("/bin/sh", ["-c", filePath+" &"]). Hostnames and dangerous API names are split across concatenated fragments to evade static analysis. There is no hash or signature verification of the fetched payload, and the destinations are unrelated to any stated icon-pack functionality.
