Is it possible to get confidential information from an apartment knowing its address and postal code?
It is theoretically possible by IP, but in a typical situation it will usually be expensive and a specialist who will do this still needs to be looked for.
There are cheaper ways offline.
If you know your e-mail or account in social networks, etc. - then you can already try to trick the user into installing a Trojan that will open the gate to your computer. This option is more realistic, usually this is how it happens. But it’s also quite easy to protect yourself from it - don’t get divorced, don’t follow left links, don’t install left software, enable UAC, work without administrator rights, install an antivirus ...
If the computer is used to work with finances or other sensitive information, then you can’t go “to the left” from it at all, only to a limited allowed list of sites / hosts on the Internet. This list must be explicitly registered in the firewall, the rest must be mercilessly blocked.
CAN.
And let the paranoid, maybe, what good will this user'a be.
Formally, having access to somewhat more data than just the IP address, it is possible to organize an attack on the user in order to upload malware to his workstation and extract the necessary information through it and the outgoing channel. You can get additional data, in principle, through social networks, if you know exactly who you are looking for, through a pixel from some not very safe resource, slip the page on which to the attacked and put a tracking cookie, then catch it somewhere in his area of interest and match with some user, and so on. Non-trivial, illegal, but possible.
Haha. You can :)
IP immediately gives geolocation. IP immediately gives the network to which it belongs (AS) - all this can be found out even if the computer is turned off. IP can be scanned for which axis is installed, which ports are open. Knowing this, you can try to pick up an exploit that will work to elevate privileges on the server. If you're lucky, you can get admin rights - and then do whatever you want...
This is of course an unlikely chain, but there is nothing supernatural in it. And if there is an ordinary Sokhovsky router, but with a default password ... :)
