Makes me wonder what other sort of things a given server is participating in without realizing it. I don't see how you could use this exact technique(TCP checksums) to mine crypto, for example, but there might be some relatively common web applications out there that could be exploited in a similar way.

You actually kinda sorta can 'mine' HTTPS - as part of a cryptocurrency which incentivizes DDoSes! https://www.usenix.org/system/files/conference/woot16/woot16...
