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.

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.

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.
* JA3s are mostly useless. JA4s supersede them entirely.
* Using JA4s in rate limits is pretty useful and helps a lot against proxy scraping. It was not very helpful in this attack.
* Bot detections are somewhat helpful but they don't solve scrapers/attacks by themselves. They're useful as a 2nd/3rd data point (eg. low bot score + bot detection + something else)
