Besides the master key, is there any effective way to crack the Wifi password?

First of all, it is scary to promote the name master key. In fact, this is not a real crack. It only records the routing name ssid, routing mac and password in different locations. When you use the software to automatically scan locally, the server will automatically compare the surrounding wifi and help you fill in the password if there is database information.

How does the master key keep these passwords? At first, it was to install software to upload passwords automatically, and later it became induced sharing. For example, letting yourself accidentally click and upload your own wifi information has always created a tall image, which makes people somewhat. . Toothless.

I'm not going to repeat what I'm bored with. Look at the blackboard. How to crack the wifi password?

Cracking the wifi password is mainly to crack wap/wap2, and wep has only five digits, which is very easy to crack. I don't know, it's mainly wap/wap2.

Huang Ka: Because the wireless network card that comes with the laptop is not powerful enough to grab the bag, I want to buy this director.

a computer

Some people find it troublesome to install BT5 dual system, and prefer to use virtual machine. Virtual machines are not recommended here, because solving the driving problem is a time black hole, which wastes a lot of time and has little effect.

Cracking step

Start the system and select the language interface. Here you choose Chinese. If you are a foreigner, choose a foreign language. I believe everyone here is from China, right?

After the virtual machine is started, it is an exciting moment. Hehe Part II: Cracking wep/wpa2 system started successfully, desktop 1, system started, this is the desktop! How's it going? Are you familiar with it? Much like win's! It's easy to get started 2. Then open the first software mini DWEP-GTK on the second line ~ ~ This dialog box appears, and click OK directly! Just after 3 o'clock. Look at the drop-down menu in the upper left corner and find your own network card! ! ! Then the upper right corner! ! Scan! ! ! Then I started to get excited! ~ 4. Are you excited enough? Do you see it? Sssid-that is, the mac address scanned by pwr to the wireless access point: signal strength data: this sentence is the so-called essid at the end of the data packet, right? That's the name of the route you scanned! Is that clear? Of course, if there is no data packet, you'd better save it! After all, it is cracking! No data packet means that you can't catch the handshake bag. How to crack the handbag if you can't catch it? So you still need a lot of data! Then I grabbed the handbag and started to crack it! 5. How's it going? Hey, hey, see? The software has searched the wpa2 encrypted router! Of course, the software search method is to search together, that is, wep and wpa2 search together. Look at the "encryption method" in the left column of the software. If wep is selected, the routes encrypted by wep will be displayed, and if wpa2 is selected, the routes encrypted by wpa2 will be displayed. What we're talking about here is cracking wpa2 encrypted routes! So wep brushed it off! If it is to crack wep routing, just press the "Start" button in the right column, and the rest will be searched automatically without hands (provided there are packets! 6. Next, start grabbing the handbag, look at the last line of the picture, grab a handbag, and wait for authentication. There will be a prompt after waiting for certification! I told you I caught the handshake bag, and then you can crack it! Of course, it takes patience to grasp the bag. Sometimes rp soars, maybe you can catch it when you come up. It took me more than ten minutes to catch it. ) 7. It has basically succeeded, and the rest is cracked! Here we begin to crack the first part, run the package and start to test the password! 8. Next, contribute your dictionary to minidwep-gtk! Hey, hey, have you learned all this? I gave him a default dictionary, which is the last wordlist.txt. You can choose a dictionary according to the situation. In fact, I have hidden more than 3g dictionaries online! Hey, hey, but this route is a weak password! So this dictionary is enough! 9. Now it's decrypted, and it's successful! See wpakey: 0 123456789.

I found an article like this because I didn't have a picture at hand. You can leave a message if you don't know anything, and you can leave a message if you need any resources.

By the way.

1, the first one can also be said to be the most effective one, that is, using lovely WiFi and other software to crack, which normal people should use. Its principle is that someone shared the password of this hotspot on the server, and when someone visits this hotspot again, it will send the password stored on the server to the mobile phone. Of course, when there is no hot password in the server, we will try to "crack" the wif password by trying some relatively simple weak passwords. This is also a common means of wifi app.

& gt02

The second is a more advanced method, which uses a dictionary (TXT document containing all kinds of possible passwords) to violently crack WiFi passwords. To put it bluntly, it is to try one by one. In this case, there is another problem, that is, speed and routing. Every time I fill in a password and then verify it in the route, it takes a long time and I can't try a few in one minute, so there are cracking software such as BT and CDLinux.

& gt03

Actually, BT and CdLinux are simplified Linux systems. Windows is not suitable for network packet capture due to its own limitations. ) We disconnect the client from the router through some software in these systems, but now WiFi devices will try to connect automatically after the WiFi is disconnected in order to provide a better user experience. In the process of automatic connection, devices such as mobile phones will resend the encrypted WiFi password to the router. After receiving this information, the router will compare it with the data stored in its own internal WiFi password by the same encryption method. If it is successful, the authentication is passed.

& gt04

At this time, these softwares will grab the data packet containing the encryption password, because the encryption method of WiFi password is one-way encryption, which means that it can only be encrypted but not decrypted (a bit like a linear equation of n yuan, you may be able to solve multiple X values by substituting a Y value, but there is only one corresponding Y value). So usually we use the password data in the dictionary to encrypt it in this way, and then compare it with the data in the packet we captured. If it is the same, the password will come out. In this case, the speed of running the package only depends on the operation speed of your computer's CPU and GPU, which can basically reach thousands of times per second.

& gt05

PIN cracking is the most effective method to crack wifi passwords in recent years. Then what is a pin? What's the use? Here's a concept first. WPS, WPS(Wifi Protected Setup) is a suggested wireless configuration protocol, and password and SSIDs are not required. Its advantage is that WPS-enabled devices can automatically establish a connection when they connect to the device for the first time, without manually entering SSIDs and passwords. It is dangerous because it is convenient. If we know the SSID and PIN of a route, then we can enter this wifi network aboveboard, even if we don't know the password of wifi. Once we know the PIN, WPA2 encryption is useless, and we can get the password through the above-mentioned golden beetle software.

& gt06

The format of PIN code is very simple, with eight decimal places, and the last bit (the eighth bit) is the check bit (which can be calculated according to the first seven bits). During verification, the first four digits are detected first, and if they are consistent, a message is fed back, so it only takes 1000 times to scan the first four digits. If the first four digits are determined, just try again 1000 times (the last three digits). So even if you don't know how to calculate the parity bit, you can try10000+100 =11010 at most to get the PIN, and then get the wifi password. Is it much easier? Let's put the picture first. Here, for the sake of argument, I will take my own road as an example. Suppose I get the PIN( 1409928 1), and this is my Tplink PIN code. Get from the routing interface.

The master key does not crack wifi, but * * * enjoys wifi. To say that only the software of Phantom wifi can crack wifi, he can crack it in an exhaustive way, but it will take a long time. But there are also the latest methods to crack pin, you can try.

This method may be a bit stupid, but it is practical and simple. . . .

Find several networks in a community or community or a place with a lot of wifi, and lose them one by one.

Just lose 12345678, that's right, it's so capricious, that is, lose 12345678.

There must be one person who can succeed.

When there is no net, I will rub it, be willful, and slowly there must be something; If there is no one nearby, change places.

Then try 12345678.

Buy spray, I'm ready. .

First of all, the master key is not cracked, but enjoyed by * *. After installing this software, you will upload the WIFI and password in your mobile phone to the server, and others will find it when searching.

I once bought Xuntuo's long-distance network card, and the seller brought a WIFI password cracking tool in the CD. I cracked it with exhaustive method and a dictionary for 4 days, but I didn't crack my neighbor's password.

First of all, it can be said with certainty that WiFi passwords can be cracked, but the problem is very difficult, especially the combination of letters and numbers. If there are special people, it can be said that it is impossible in terms of personal hardware conditions.

Can the master key really crack the password?

Many people say that apps like the master key can crack the WiFi password, because even if you go to a strange place and open the master key app in your mobile phone, you can connect to the local WiFi smoothly, so everyone knows that the master key is too powerful and WiFi can also be cracked.

Actually, it's wrong. The master key can't crack the password. In essence, an app like the master key shares the WiFi password, or it steals the password without the owner's consent.

What do you mean? It is necessary for us to understand the working principle of the master key: if you have a master key on your mobile phone, when you connect your home WiFi hand at home, the master key in your mobile phone will upload your home WiFi password to your server and save it. At this time, your neighbor also uses the master key. When he turns on the master key on his mobile phone, he will automatically search nearby WiFi to see which WiFi has a password stored on the server.

At this time, you are a tragedy, because your WiFi password has been uploaded to the server by the master key APP in your mobile phone, so your neighbors can automatically and smoothly connect to your WiFi network.

If you still have NAS, computers, printers and even cameras at home, if one of your neighbors is a technology geek, the consequences can be imagined.

Can I get my WiFi password back if I forget it?

Share a little trick. Because the WiFi at home is in the mobile phone, it remembers the password, so it is automatically connected every time I go home, but I forget the password after a long time, especially if I change my mobile phone, I can't try it out anyway. Aren't you sad?

In fact, it is not necessary to reset the router to retrieve the WiFi password. We have a simpler and faster method, as follows:

1, the old mobile phone opens the WiFi list, finds the home WiFi name, shares it, and a QR code appears:

2. Scan this QR code with the WeChat of the second mobile phone, and you can see the name and password of WiFi:

It is not recommended to reset the router because many other devices in the home will be very troublesome if they are connected to the wireless network.

In addition to the shared cracking of WIFI master keys, there are two mainstream cracking methods at present, and the technical terms are running Pin and grabbing packages. The so-called running Pin is actually to find the pin code corresponding to the router, so as to obtain the password of the connection. The so-called pin is equivalent to a proof of this router. If you find it, you can find other information. Cracking passwords with CDlinux (CDLinux forum has tutorials). This way, no matter how the other party changes the password, you can't stop surfing the Internet.

Of course, to solve this problem, you can basically solve the internet problem by turning off the WPS function of the router (specific tutorial Baidu). The so-called running needle is actually an exhaustive method. As long as 10 1000 pin codes are used up, you can find your pin code again. The advantage of this method is that the probability of obtaining the password is high, but depending on luck, it may not run for a week. Pin codes are composed of random 8-digit numbers (between 000000000 and 9999999), but they are combined in the form of arrays, and the combination mode is 4+3+ 1. All four digits and 1 digits add up to * * * 1000 possibilities, so

Actually, grabbing a bag is similar to running a pin. By intercepting the authentication information when the router is connected to the user terminal, the virtual machine obtains the handshake package and then uses the password dictionary to look it up. Of course, the password obtained in this way is one-off, and it can't be used after being changed. For specific operations, Baidu has a detailed tutorial on "grabbing packages and cracking wifi passwords".

Just ask directly.

1, with the existing technical means, there is no way to crack WAP encryption (now it is basically WIFI encryption), and WAP encryption is highly secure and cannot be cracked at all.

2. Even if the password is cracked, people may have set up MAC address filtering, but you still can't get on.
