How to Identify a User by IP Address
Imagine a situation: you have a user's IP address in your hands, and your task is to find out their identity. There is a lot of information on this topic on the internet, most of which has questionable effectiveness and value, and some authors even believe that it is impossible. But it is possible, and I will show you how it is done.
To start identifying the owner of an IP address, you need to perform a simple check of the IP information, which can be done on this website. It is important to understand whether this is the real IP address of the target or if tools are being used to hide it. If the IP address belongs to a hosting provider or the Tor network, then we are dealing with a server that is hiding the user.
Here is an example of a user's IP address using a VPN. The server belongs to the hosting company Digital Ocean, which has rented the server with this IP to the owner of the VPN service Browsec, who then provided access to the client.
As part of the course, we will teach you more complex methods of verification, such as analyzing open ports, ASN, or bidirectional ping, which can provide an accurate answer about the use of proxies, VPNs, or Tor to hide the IP address. But for basic verification, it is sufficient to determine the Internet Service Provider (ISP) and the country of the IP address.
It is important that the person of interest does not use means to conceal their real IP address. De-anonymizing users of proxies, VPNs, and Tor is possible, but significantly more complicated, and often requires an attack through external channels. For example, a timing attack using a messenger can establish the identity of even an advanced paranoid who does not leave the Tor network.
Here is an IP address belonging to a regular Internet Service Provider.
If the IP address belongs to an Internet Service Provider, it is necessary to find out to whom this IP address was assigned. This information is only available from the Internet Service Provider, to whom law enforcement agencies send an official request and receive information; hackers, on the other hand, order data breaches at https://book.cyberyozh.com/ru/deep-web-ili-glubinnyij-internet-tor/.
