Cloudflare just stopped, (almost) automatically, a big attack against our company

The attack started at 4 AM and its still ongoing now (I’m tuning the rules a bit, they seem to be changing patterns but the automated protection is doing a major part of the mitigation).

Its VERY well distributed.

Thats a lot of requests! Sit back and let Gatebot do the work :sunglasses:


Is your site still responding to legit requests like normal or are you seeing some impact?

It is doing an awesome job actually! I only had to add rules for “leftovers”.

Approximately 87% of the attack was automatically mitigated


I managed to find a common pattern for the attack, legit visitors do not even get to see a 5s screen currently. However, when I was still inspecting the behavior, legitimate visitors had to face a 5s screen or captcha.


Here is the bot protection verdict on those requests:

Unfortunately we can’t tune it, but had bot management allowed me to whitelist a bunch of IPs and maybe, the whole attack would have of been mitigated without any human interaction.

The attackers seem to have given up on attacking the website, they are targeting our servers now but we got that covered as well.

Someone’s really crashing your cake day party. Good thing you hired a :orange: bouncer at the door.

They are even doing a follow-up now! The party never ends for these people hah. This time 70% was automatically mitigated and 30% was thanks to some of the firewall rules I deployed earlier.

The attack pattern changed but it’s still slightly similar.
