There’s an assumption that turning on Cloudflare’s “under attack” mode would mitigate the attack.

Given how adaptive the rest of the attack was, I would be very curious to find out how it would approach that obstacle.

That has only partially mitigated much smaller attacks (residential proxy scraping etc) on my employer's site.

We're currently on the "Business" plan, but I'm coming to the conclusion that we need to upgrade to the "Enterprise Advantage" plan for the JA3/4 fingerprinting and detection ID features.

I get put off by "Contact Sales" pricing.

My assumption would be that it would drastically reduce the attack to be borderline irrelevant. I've never turned on Under Attack so somebody else may have more insight and the docs[1] don't describe precisely what happens besides a JS interstitial.

I know that JS challenges, both interactive and non-interactive, can be solved by bots. I've seen it. However, I suspect that the challenges just get harder and harder until the attack levels drop.
