specials-resources-server@35.8.1 is a staged remote-code-execution dropper disguised as an 'Analytics SDK'. Both the package main (lib/telemetry.js) and shim.js execute the same payload on require(): they select a platform-specific path, fetch an opaque binary from a rotating list of Cloudflare Workers subdomains (oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev) with a DNS TXT fallback under sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru, base64-decode chunks, write to /var/tmp/.cache<hex> or %TEMP%/dotnetdiag<hex>.exe, chmod 0755, and detached-spawn via /bin/sh -c or cmd /c start. The destination hosts are anonymous Cloudflare Workers subdomains, not the package publisher; there is no hash or signature verification; the on-disk names impersonate cache and dotnet-diagnostic files. Endpoint hostnames and privileged API names (childprocess, chmodSync) are reconstructed by string-concatenation and array-join to evade literal-string scanners, and a /tmp/.analyticsstate TTL marker gates re-execution. Any consumer that imports the package triggers the dropper.

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.
