No, that would usually be intermediary. If you want to be more specific you can say reseller or broker.

Monster in the middle is at least cute and conveys the authors intent that this agent is untrusted and assumed malicious.

People in this thread clearly don't like being called a monster which I think demonstrates exactly that words matter and these ones are doing their job.

No one here is objecting to it as a standalone phrase, but as a replacement for a perfectly good phrase that existed all ready. There is no reason to change existing terminology and cause confusion; who decided this was a problem, any way? It reminds me of Bro being renamed to "zeek" because of the whole "brogrammer" thing, even though it was named before any one ever started complaining about that after Big Brother. It's not a real issue. I wouldn't have a serious problem with it, except that some one who wants to learn more is now stuck searching for one of the three other people who decided this was an actual issue and used it instead of MITM. Again, same as with Bro: now you have to search for two terms, even if you're familiar with the distinction. I can find posts going back to the 90s on Bro; "zeek" has very little in comparison.

It turns out even cloud flare used man-in-the-middle in the project, because it was in some other code, I guess: https://github.com/cloudflare/mitmengine/blob/master/process...
