Question

Information Security

Can someone outside come to my home ip address and access the internet????

Answer 1

Yes
, but it depends on the settings of the router, PC, provider, etc., etc...

Answer 2

Yes. Is that possible.
This is called a residential proxy, which in most cases is installed on your PC and uses your Internet from your ip address unauthorized. Most often, this is some kind of virus that you picked up on torrents or somewhere else.
Then your ip address is sold as a proxy. Residents often fly offline (let's say you surfed the Internet, played games, you were invited to take a walk and you turned off your computer). Therefore, residents are most often sold as a proxy pool with rotation.
Such proxies are used by all and sundry. If you buy as a pool, it comes out cheap. Such proxies are less scorched by all sorts of search engines / marketplaces, etc. Therefore, such proxies are usually taken for parsing, autoregistration, spam, cheating, etc.
It may also be that there is a vulnerability in the software of your router, the same proxy is uploaded there and it already works on the router. That is, even after turning off the PC, your proxy will be active.
I'm not talking about responsibility specifically. Yes, if someone commits a crime from your ip, they will come to you first of all. But any criminologists have long been aware of how such crimes are carried out and will look at the computer in the first place. They will check the logs, the presence of viruses on the PC, and so on. To sit down for the fact that you have a proxy on your computer and someone through it committed a crime is almost zero. If you haven't done anything wrong, you have nothing to be afraid of.
And according to judicial practice, you can look at the experience of Tor weekend node admins in Russia. As far as I remember, none of the admins were imprisoned. But there is a fact of traffic proxying (list of nodes in the public domain).
