Extratorrnet.cc Proxy [extra Quality] -

But why? What was the purpose?

To test the proxy's behavior, I crafted a manual announce request using cURL: extratorrnet.cc proxy

In the end, the Reddit user was told to simply remove the tracker from their torrent's properties. It wasn't malware. It was just a relic. And sometimes, that's the most interesting thing of all. But why

http://extratorrnet.cc/announce

That was it. The torrent file, likely created years ago and re-uploaded to modern sites, still contained a dead tracker from the Extratorrent era. Some clever operator had bought the domain extratorrnet.cc and set up a lightweight, always-on announce proxy. Their server listened for scrape and announce requests, pretended to be the old Extratorrent tracker, and responded with a standard "peers list" — which was likely empty or synthetic. It wasn't malware

The OP was confused. "I never set up a proxy," they wrote. "Is this malware?"
