Entering the network, the user leaves information about his ip-address on each resource he visits. This address is unique, there cannot be two or more computers with the same ip on the network at the same time. Therefore, information about it, if necessary, can help to calculate the owner of a particular computer.
Instructions
Step 1
Hackers are very well aware of the fact that the ip-address allows you to determine who visited the site or connected to a particular computer. That is why they are taking all measures to hide their real address. It is possible to calculate a person by ip only if he was not hidden, for example, by connecting through a proxy server.
Step 2
First, you need to determine the ip-address of the computer from which the person of interest connects to the network. This can be done in different ways, here a lot depends on the specific situation. For example, if you received a letter, look at its header - it always contains information about the sender's ip-address. The title here does not mean the subject of the letter, but the service information that comes along with the text. For example, in the Rambler mail service, to view the header, open the letter, select "Other actions" - "Mail headers" from the menu.
Step 3
A properly configured computer never "climbs" into the network itself. If you see the connection icon in the system tray becoming active every now and then, check your network connections by typing netstat –aon at the command line and pressing Enter. To open the command line (console) go to: "Start" - "All programs" - "Accessories" - "Command line". In the column "External address" you will see all the connections of your computer.
Step 4
A suspicious ip-address should be checked on one of the network services that provide the who-is service. For example, here: https://www.nic.ru/whois/. You should know that at best you will be able to determine the provider through which the owner of the ip you are interested in is connected to the network. If any illegal actions were carried out against you from this address, you can report this to the provider, indicating the exact time, your ip-address and describing the situation. In any case, no data about their client will be reported to you, such information is issued only to law enforcement agencies.
Step 5
If you were able to determine the ip-address of the person you are interested in, the only real way to collect any data about him is through hacking his computer, which in itself is illegal. Such actions can be justified (from the point of view of morality, but not the law) only if this person deceived you or committed other illegal acts, while you did not succeed in achieving anything by legal methods. In this case, you have the right to defend yourself.
Step 6
Search the web for the Metasploit program, read the available information on its use. There are versions of the program for both Windows and Linux, this is a completely legal application for testing the system. Using Metasploit, you can scan a remote computer for vulnerabilities. If they are, you will have the opportunity to penetrate the attacker's computer and collect the information you are interested in.
