The Cloudflare Poison (sh.itjust.works)
submitted 5 months ago* (last edited 5 months ago) by [email protected] to c/[email protected]
 

Daily reminder that sites "protected" by cloudflare are effectively MITM attacks. HTTPS is now even more worthless. Cloudflare can see everything. this is a known fact and not a theory.

And if you think Cloudflare aren't being tapped by the NSA, you're sadly sadly naive.

All the "privacy respecting" sites use it too. So remember, as soon as you see that cloudflare portal page, you can assume that everything you plug into the site is property of NSA Inc. Trust no one, and do not trust code being served to you over the web if it comes through CF, there is no way to know what they've modified.

But in the end, yes, it is a MITM. If you need your data to be E2E encrypted, don't use it.

Or do use E2E encryption. You can still have a layer of encryption within the SSL tunnel that cloudflare controls. Like you'd do for an E2EE filestore: the webserver (and cloudflare) see the website woosh by, and all that you do on it, but the files themselves are encrypted opaquely to both, and decrypted only by a browser at the other end.
