Can the master key really unlock all WiFi passwords?

Can the master key unlock all wifi passwords? I think it's wishful thinking . . . This absolutely does not exist. On public occasions, when you open the wifi master key, you can often find more than a dozen wifi signals, of which two or three can be connected.

these wifi are not secret-free, but they can indeed be linked through the master key. Many people mistakenly think that they have cracked the passwords, but in fact, they have nothing to do with the wool. These passwords are illegally obtained.

Not to mention, the internet that everyone can surf is not safe at all. It's disgusting just to get the password!

The general process is as follows:

1. When users use the master key, they think they are surfing other people's networks, but in fact, they have leaked all the wifi passwords stored in their mobile phones (your family's, or your little uncle's, aunt's, girlfriend's) and uploaded them to the wifi master key server without the user's knowledge, including the hotspot name (or the mac address of the device) and password.

2. When someone wants to visit your home network one day, the system will match the relevant hotspot names and passwords in the massive database. If the matching is successful (Congratulations, become a living Lei Feng. . . ) can be returned to the surfer for use.

3. In case the server can't find a matching password, try a simple cracking method, and apply very simple passwords such as 12345678, 6666666, 8888888, etc. If all fails, I will tell you that there is no wifi available in the attachment. . . It won't give you an exhaustive method to crack it violently. .

All these operations are bullying those little whites who don't know anything. As an Internet company, it can be said that it is really a dog. .

However, the terrible thing is that we don't care at all about our privacy and personal information being leaked. . Inexplicable sales calls and spam messages seem to be numb!

Although it is said that the application of "WiFi Master Key" allows users to access the WiFi network that they did not know the password and could not connect, thus saving the traffic of their own mobile network. However, if you have never used the App, others can't connect to your WiFi through the "WiFi Master Key"; Even if you have downloaded the App, others still can't connect to your WiFi through the "WiFi Master Key" until you perform the operation of "* * * Enjoy WiFi".

WiFi information is leaked

In fact, "WiFi is enjoyed by * * *" is not only that the player has used this kind of "* * * WiFi" application, or it may be that you told the guests who visited your home the WiFi password, and then it was shared by the "WiFi***" application on the other party's mobile phone, or it may be that your WiFi password is too simple.

at present, in addition to the "WiFi master key", we can also find many apps with functions and even interfaces that are very close to the "WiFi master key" in the mobile phone application market, and many of them will upload users' WiFi information and enjoy it, which makes many users who use such applications reveal their WiFi passwords. Of course, it is accompanied by all kinds of internet surfing.

the WiFi master key cannot unlock all wifi. At present, most WiFi passwords are combinations of numbers, English and even characters with more than 8 digits. If we rely on exhaustive methods to crack passwords, it may take decades to crack a complex set of 8-digit passwords. Therefore, it is almost impossible for a normal password to be violently cracked.

so how does the WiFi master key crack the password of Lao Wang's house next door? In fact, this kind of software has the following basic cracking schemes:

1. Cloud data * * * Enjoy

If someone in Lao Wang's house next door has used software such as WiFi master key, his family's WiFi password and router Mac address will be automatically saved in the cloud server of master key. When another person opens the master key and selects the WiFi name of Lao Wang's family, the master key will automatically find the WiFi password saved in the server through the Mac address of Lao Wang's router, so that even if it is not Lao Wang's family, you can connect to Lao Wang's family's network through the master key software.

The way to prevent your router WiFi password from being collected is also very simple, just uninstall the software such as the master key.

However, it is inevitable that guests will connect to your home WiFi with a master key when they are at home, thus revealing their passwords. At this time, you need a router that can set the password of "temporary guest", which is generally available in intelligent routers. The function of "temporary visitor" is to separate the password used by the host from the password used by the guest. When a guest comes to the home for networking, he only uses the guest password, and after the guest leaves, the guest function is turned off in the background of the router. In this way, the master password will not be leaked, and even if the visitor password is collected by the master key software, it is of little use.

Second, dictionary brute force cracking

Although it is impossible to crack the normal 8-digit WiFi password through exhaustive methods, some users are lazy to set too simple passwords, which gives this kind of software an opportunity. Generally, master-key software has a password dictionary built in, which contains many simple passwords that are often used by people, such as:

password

12345678

a1234567

abcdefgh

and so on. This kind of password is very simple. If master-key software can't find the password of the corresponding router in the server, it will try it first.

The way to deal with this cracking method is also very simple. Just set the password a little more complicated, such as setting it to your pinyin initials +12345678, which is not only easy to remember, but also impossible for ordinary people to crack at all.

In addition, a slightly smarter router has the function of "multiple password errors and refusing to connect". When the other party tries to crack the WiFi password with the master key for many times, once the number of errors exceeds a certain number, the router will disconnect the device and refuse to join again, which can also prevent the master key from using the "password dictionary" to crack the password at home.

can the master key really unlock all WiFi passwords? This is impossible. I don't know others'. Let's talk about this universal WiFi I downloaded now. Sometimes it can be cracked, sometimes it can't be cracked. If others' password settings are simple, they can't be cracked. I found that I can connect to public places as long as I use WiFi, but I don't even connect to WiFi if I have to pay for it.

crack? Nani?

The speed at which hackers crack WiFi passwords is directly related to the complexity of passwords, the "password dictionary" used by hackers, the computing power of computers and other factors. According to the current mainstream WPA/WPA2 encryption, the actual test results show that: < P > First, pure digital passwords are the weakest! Generally, it can be cracked within 5 minutes. The more regular the combination of numbers is, the faster the cracking speed will be. For example, weak passwords such as 12345678 and 8888888 are all in front of the password dictionary and can be basically broken in seconds.

second, the combination of lowercase letters is the second, and most of them can be done within 1 minutes. The best combination of lowercase letters to crack is also a common weak password, such as password, iloveyou or qwertyui (looking down at the keyboard without understanding), which can even run out of the password dictionary faster than some digital passwords;

third, it is relatively difficult to crack the mixed passwords such as "lowercase letters+numbers" and "uppercase and lowercase letters". If you encounter common passwords such as asd123456 and abcd1234, you can solve them within one hour. If it is a strange and uncommon combination, it may take several hours;

fourth, the most difficult to crack is the combination of "uppercase and lowercase letters+numbers+special symbols". Under normal circumstances, if you can't crack it within a few hours, the hacker may give up. (Excerpted from Netease Digital)

Want to use the Internet? Wait an hour first!

in addition, have you considered the legal risks faced by enterprises?

the wifi master key has three main channels to obtain wifi hotspots:

first, the sharing of hotspot owners

second, the self-built network (buying traffic from operators)

third, the cooperation with merchants (mainly to save users unnecessary troubles)

The answer is: theoretically possible! It is impossible in reality.

first of all, let's talk about the principle of the master key. The master key will first look up whether there is this WIFI on the server, and search the data according to the name and IP address of the WIFI. If it is found, congratulations on getting the password. This is the fastest way. This method is more common in some public places, such as the WIFI in a hotel or shopping mall. As long as someone has opened it with a master key, the password will be saved in the server. You can get the password directly in the future. Convenient and quick.

if the password of this WIFI is not found in the database, then the master key will collide with the database, for example, he will use 12345678, abcdefgh and so on to compare one by one according to his algorithm until the password is correct. So when our password is not only numbers and letters, but also other special symbols, and then the number of password bits is set very long (such as 18 bits and 32 bits), then the probability of cracking is very low. It may take years, decades, or even hundreds of years to crack a password, and we will basically think that it is impossible to crack it. Of course, some routers have a limit on the number of connections. If a device is wrongly connected for many times in a row, then you will not be allowed to log in again.

So for our security password to be complex and as long as possible, the security factor will be high and the probability of cracking will be lower and lower. Even if it can be cracked, it will be decades later, so the master key can't really unlock all WIFI passwords, only most relatively simple passwords.

In fact, there have been many related reports and articles on this issue, and I have done experiments myself, which prove that this master key can't unlock all WiFi passwords, but at most it can crack some simple passwords, and its main function is to share the passwords of the WiFi you have connected.

if you use this master key to connect to your home WiFi for the first time (of course, the premise is to enter the password), after connecting, it will automatically upload your home WiFi password to the cloud and share it with everyone, so that other people can automatically connect to your home WiFi near your home with this software, as simple as that. But it is for this reason that people love and hate this master key.

People who like this software are of course those who love surfing the Internet. You can use the master key to get free online anytime and anywhere. People who hate this software think it is a bit evil, and unconsciously let the WiFi password at home leak out, which is hard to prevent, directly causing the network card to be slow and seriously affecting the experience.

tell me something you have encountered. In the past, people often came to work to ask for the WiFi password, so we told him, but in fact, I found that someone used the master key software to connect, so of course, people nearby could surf the Internet for free. One day, the boss said that WiFi was too stuck, so he changed a very complicated password, but it didn't work soon. I said, it's no use, unless you ask others not to connect to this WiFi with a master key, but can they all understand this truth? Can you prevent others from using it secretly? It's really difficult.

My mobile phone has a lot of traffic. If someone wants me to turn on a hot spot sometimes, I will turn it on for him. But you even use the master key, and you tell him that he doesn't understand. That's great, everyone can use the hot spots, and they don't know how the traffic is consumed. So as long as I suspect that someone connected my hotspot with a master key, I will change my password immediately after I use it. Well, that's all for today about this master key.

no matter what software is used to crack the wifi password, it can't be cracked completely. The master key can crack the password, as long as it is digital, it is easy to crack. The wifi password in the neighbor's home is composed of two mobile phone numbers (22 digits), which is also cracked. Secondly, there are several English letters in front of the password, several numbers in the middle, and English letters behind it. Maybe someone else shared it, and it was also cracked with the master key. In addition, the wifi password in the neighbor's home must be a little more complicated, and it is a failure to crack it with the master key countless times. Download other password cracking software again, but it still can't be cracked. The master key has an obvious disadvantage in cracking the wifi password. If the other party is good at it, he can steal the software with a deposit account on your mobile phone. There is deposit software on your mobile phone, so use other people's wifi for as little time as possible, and don't use it often for a long time!

the master key can't unlock all the passwords of W I F I!

However, many mobile phone users actually downloaded this App!

it should be said that many times, in different places, users do get a lot of free networks!

but I also downloaded this App! But I just don't know how to use it!

during use, it's ok!

At present, I think "Connect to the Internet" is also very useful among the settings that come with the mobile phone.

When we usually connect to the free network, we are required to enter a simple number when entering the network password. Such as-123456789

can often connect to the free network.

The passwords of these free networks are just like the passwords of bank passbooks.

use simple numbers as passwords.

such as

666' 6666

88888888

method! Try again and again!

people often have some misunderstandings when using the master key. Let me list them one by one.

1. the wifi master key is the software to crack wifi. This statement is all wet. The master key is just a software for sharing hotspots. In short, users share their passwords to the cloud through the master key, and then if others meet the hotspots you share, they can connect with the master key.
