I do the same. 3 different browsers: work, personal and random stuff. Keeping them isolated from each other clears the clutter and my focus when working.
That's a problem that will only get worse. To give an example, last year, Incapsula recorded ~9,000 IoT cameras attacking them. A few months ago, Sucuri recorded ~25,000.
CloudFlare is seeing close to 50k. And that's the attackers just using a small portion of their real power for http floods.
Our report from a few months ago breaking down the types of cameras and networking doing the attack - very similar to what CloudFlare saw:
Very fun read. I love following the train of thought and seeing where they "failed".
Also, this Elasticsearch RCE has been patched a while ago and we still see a lot of servers hacked because of it. In fact, there is a DDoS botnet made of only ES servers that we have been tracking.
<unrelated>If you are using Elasticsearch, please patch it!</unrelated>
Curious why you say that of Sucuri? Have you tried us recently?
We have some very very large sites using our services now with great performance. During the last 6-12 months we basically rewrote our entire stack, built our anycast network and focused a lot on performance optimization and expanding out services.
Some of those have many trackers and background sub domains that add up.
For example, Linkedin their most popular sub domain is: px.ads.linkedin.com
Here is a more comprehensive list with top 10k domains (including sub domains):
