Stay tuned ..

Today we can help quite a bit by proxying TCP traffic using Cloudflare Spectrum, e.g., spoofed traffic will never reach origin as it can't complete a handshake, we can use things like SYN cookies to challenge source, etc.

In the future, there's a lot more we plan to do here.

I first learned that someone cracked my app from a company that offered to help me fight cracked downloads of my app. I was immediately suspicious.

This isn't new; it's called a protection racket and it works especially well if you actually do have a mechanism to protect against the thing (though of course that's not a requirement if you're generating most of the problem yourself).

Cloudflare Spectrum can already protect arbitrary TCP services, such as SMTP or IMAP
