See how experts can crack router user passwords to control a local area network

If someone in your local area network has used software like "P2P Terminator" to restrict the other party's network speed, you will definitely give a fatal counterattack, and the ultimate result is that the entire local area network will be paralyzed.

If someone on your local area network is using B2B to download without interruption, you must want to unplug their network cable and set an example to others.

In fact, if you can enter the routing management backend, you can control the entire LAN computer, and the above concerns are unnecessary.

Today, let's take a look at how experts can crack router usernames and passwords to gain local area network control. Network Switches

1. How to know the gateway address

The gateway IP is generally 192.168.0.1 or 192.168.1.1. You can also check the status of the "Local Connection" by opening the "Network Neighborhood" attribute. In the "Support" tab, it will display "Default Gateway", which is the address of our local router. Vehicle Router

The same effect can be achieved through the DOS command. In the "Start" - "Run" dialog box, enter "cmd" to open the command method, and then enter "ipconfig/all" to obtain the local gateway address. Ac Controller

2. How to know the gateway port

In general, no one changes the initial port of the router, and entry-level routers also do not have this function, so enter the gateway address http://192.168.0.1 You can enter its WEB management interface. But experienced administrators may change the default port to a different port for security reasons, so we cannot log in through port 80. But don't worry. We can use the port scanner to find the login address of the router management interface.

For example, I used this compact port scanner ScanPort to scan all open ports of the router, filling in the router's IP address 192.168.0.1 at the "start" and "stop" positions. Set the scanning port to 1-65350. After setting up, click the "Start" button and you will soon be able to find the login port on the router's management interface. To test whether the port is correct, we can enter it in the IE address bar[ http://192.168.1.1: If the port number is correct, the router's login interface will appear.

3. How to crack the username and password of an administrator

If you're lucky and the administrator account password is still the factory value, it's amazing. Just try a few commonly used initial account passwords. For example: "admin, admin"; "root root"; "user user"; "admin password"... You can try it one by one. However, if the administrator username and password have already been modified, it will be more troublesome.

In this situation, we need to use the "Web Password Cracking Tool" and "WebCrack" to help. Simply put, password cracking on web pages like this involves using exhaustive methods to read preset passwords from matching dictionary files and try them one by one. This relies on the speed and durability of the computer. Passwords that are short and simple may only take a few minutes, but passwords that are too long and complex may only take a few days and years.

Download WebCrack and install it. After running, first click the browse button in the "User Name File" section to create the file. Then we will find some matching dictionary files, which contain various user names and passwords generated by the software for matching, such as admin, 123456, and other common user names. Of course, the more data in the dictionary, the higher the probability of cracking, and the input format of the password is one line at a time. Return to the WebCrack interface, check the "Use username dictionary" option, and browse to select the text document you just created. Next, fill in the login address of the router in the "URL". After setting it up, we click the "Start" button to explore.

After the detection is completed, we can click on the "Results" button and switch to the "Discovered Password" tab to view the detection results. At this point, the router will be taken over by us, and you can do whatever you want next, but don't go too far. Be careful when others dial the network cable!!
