Hello, I’m getting a lot of traffic from a certain header called “app.yuasha”, how do I block it?
Could someone tell me a specific WAF rule for this? I’m a PRO Plan.
Sure, just go to Security → WAF → Custom Rules → Create Rule (Magic Link: https://dash.cloudflare.com/?to=/:account/:zone/security/waf/custom-rules/new),
Field Header
Name x-requested-with (header names are case-insensitive and must be lowercase with custom rules)
operator equals
Value app.yuasha
Action: block
If you wanted to block multiple, you could use operator: is in and type them out.
(100 requests isn’t exactly a lot of traffic though, I wouldn’t be too concerned/trying to constantly block those requests unless they’re actually causing issues/high in volume)
