That doesn’t work that way.

IP addresses are fairly public.

In order to get that kind of infection there need to be a serious vulnerability. None of the services I expose have those kind of vulnerabilities, and I keep them updated.

A Zero-day may be possible, but it can happen with any software.

Any way, even if Some of my services got infected that way. I have them all in docker containers. If the managed somehow to insert any malicious software it would have disappeared in the following restart of the container.

And in order to have a software that breaks out of the container it would need to also have some sort of zero-day docker exploit. Two zero-days needed for accomplish that…

Every expose software I have is running on a caddy reverse proxy. And caddy is the only authorized author on my firewall so it gets more difficult to try to run an unexpected malicious software.
