Can the master key really unlock all WiFi passwords?

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

These wifi are not secure, but they can indeed be linked through a master key. Many people mistakenly think that they have cracked the password. Actually wool has nothing to do with wool. These passwords were obtained illegally.

Not to mention, the Internet, where everyone can access the Internet, 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 browsing other people's networks. In fact, they have leaked all the wifi passwords stored in the mobile phone (yours, or your little uncle, aunt or girlfriend's) without the user's knowledge, and uploaded them to the server of the wifi master key, including the hotspot name (or the mac address of the device) and the 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 match is successful (congratulations, become a living Lei Feng. . . ) can also be used by surfers.

3. In case the server can't find a matching password, try a simple method to crack it, and apply very simple passwords such as 12345678, 666666 and 888888. 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. .

This series of operations are bullying white people who don't know anything. As an internet company, it can really be a dog. .

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

Although the application of "WiFi master key" allows users to access the WiFi network that they can't connect without knowing the password, thus saving the traffic of their mobile network. But 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 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 * * *" is not only that the player has used this "WiFi * *" application, but also that you told the guests who came to your home and then enjoyed it by the "WiFi***" application on the other party's mobile phone. It is also possible that your WiFi password is too simple and can't be enjoyed by others.

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

The WiFi master key cannot unlock all WiFi. At present, most WiFi passwords are combinations of numbers, English and even more than 8 characters. If you rely on exhaustive methods to crack passwords, it may take decades to crack a complex set of 8-bit passwords. Therefore, it is almost impossible for normal passwords to be cracked by violence.

So how does the WiFi master key crack the password of Lao Wang's house next door? This kind of software actually has the following basic cracking schemes:

First, cloud data * * *

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

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

However, when guests are guests at home, it is inevitable that they will use the master key to connect to your WiFi, thus revealing the password. At this time, you need a router that can set the password of "temporary guest", which is generally available in intelligent routers. The role of "temporary visitors" is to separate the passwords used by the host from those used by the guests. When guests come home to connect to the internet, they only use the guest password. After the guests leave, the guest function is turned off in the background of the router. In this way, the master password will not be revealed, and even if the guest password is collected by the master key software, it is useless.

Second, the dictionary was cracked by violence.

Although the normal 8-bit WiFi password cannot be cracked by exhaustive methods, some users are too lazy to set too simple passwords, which gives this kind of software an opportunity. Master key software generally has a "password dictionary" built in, which contains many simple passwords that people often use, such as:

password

12345678

a 1234567

abcdefgh

Wait, this password is very simple. If the master key software cannot find the password of the corresponding router in the server, it will try these common weak passwords in the password dictionary first.

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

In addition, a slightly smarter router also has the function of "multiple password errors, 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.

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:

First, pure digital passwords are the weakest! Usually it can be cracked in 5 minutes. The more regular the number combination, the faster the decoding speed. For example, 12345678, 8888888 and other weak passwords are all in front of the password dictionary and can be broken in seconds.

Secondly, lowercase letters are combined, and most of them can be completed in 10 minutes. The best combination of lowercase letters to crack is also a common weak password, such as password, iloveyou or qwertyui (you can't understand it by looking down at the keyboard), and you can even run out of the password dictionary faster than some digital passwords;

Third, it is relatively difficult to crack mixed passwords such as "lowercase letters+numbers" and "uppercase and lowercase letters". If you encounter common passwords such as asd 123456, abcd 1234, you can get them in one hour. If it is a strange and unusual combination, it may take several hours;

Fourth, the most difficult to crack is the combination of "uppercase and lowercase letters+numbers+special symbols". In general, if it can't be cracked within a few hours, the hacker may give up. (Excerpted from Netease Digital)

Want to use the net? Wait for an hour first!

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

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

The first is the sharing of hotspot owners.

The second is self-built network (buying the traffic of operators).

Third, cooperation with merchants (mainly to avoid unnecessary troubles for users)

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

First of all, let's talk about the principle of master key. The master key will first find out whether there is this WIFI on the server, and conduct data search according to the name and IP address of WIFI. If you find it, congratulations on getting the password. This is the quickest way. This method is common in some public places, such as WIFI in hotels or shopping malls. 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 database can't find the password of this WIFI, then the master key will crash into 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 (for example, 18 bits, 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 basically think it is impossible to crack it. Of course, some routers have restrictions on the number of connections. If the device is connected incorrectly for many times in a row, you are not allowed to log in again.

Therefore, the more complex our security password is, the longer it is, the higher the security factor will be and the lower the probability of being cracked. 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.

No matter what software is used to crack the wifi password, it is impossible to crack it 100%. The master key can crack the password, as long as it is a number, it is easy to crack. The neighbor's wifi password consists of two mobile phone numbers (22 digits), which was also cracked. Secondly, the password is preceded by several English letters, followed by several numbers. It may have been shared by others, but it was also cracked with a master key. In addition, the neighbor's wifi password 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 obvious disadvantages in cracking wifi passwords. If the other person is good at it, he can steal the software with the deposit account on your mobile phone. There is deposit software on the mobile phone, so try to use other people's wifi as little as possible, and don't use it often for a long time!

Is the WiFi master key really omnipotent? Of course not. But how omnipotent can it be?

First of all, we must understand what mechanisms these wifi master key apps are.

Apart from some open wifi, how does the WiFi master key let you connect to those WiFi with passwords?

This is the method.

The wifi you are connected to is not cracked by this App (it is illegal to crack someone else's password privately), but shared by others when using this App.

When the App similar to the WiFi master key first appeared, there was a stupid way to "crack" one password at a time, which was characterized by simple numbers being easy to crack, while letters and numbers being mixed together were difficult to crack. This method is basically prohibited because it does not conform to the legal norms.

At present, the method of using wifi master key is not "cracking", but "* * * sharing". As long as the user clicks to share as public WiFi when using the WiFi master key to connect to WiFi, the password and location information of this WiFi will be uploaded to the cloud by the WiFi master key App for all users who use the WiFi master key.

In other words, the WiFi you can use with the WiFi master key is shared and uploaded by others or yourself.

If you use the WiFi master key to connect to an unshared WiFi and you don't click Share, the WiFi will not be automatically connected by other WiFi master key users.

After all, there are great legal risks in stealing and revealing user information without consent, and it is still easy to be found. An App that wants to operate normally does not dare to disclose your information casually. As long as the relevant departments strictly monitor, we don't have to worry. However, in case of malicious disclosure, we must also do a good job in safeguarding rights.

Compared with * * * enjoying a bicycle, this way is closer to the real concept of * * enjoying the economy, which is also explained by the government in the fiery public welfare sharing plan.

As a platform for storing public WiFi information, the WiFi master key is uploaded by users, benefiting more users. However, it is impossible to identify that users share public WiFi and private home WiFi, so when your friends use the WiFi master key to connect to your home wireless network, just click * * * to enjoy it, and your home WiFi information will be "cracked" into public WiFi. If you find that the WiFi at home can be connected with the WiFi master key at will, it is recommended to change your name and password immediately.

For public WiFi, the WiFi master key is still of great benefit. When you sit in cafes, restaurants and other places, you can connect automatically by opening the App. If no one has shared it, you can ask for a password before sharing it. Not only themselves, but also all WiFi master key users can automatically connect when needed, which is beneficial to others and very convenient.

Therefore, the WiFi master key is actually a WiFi*** key, not a panacea.

Finally, you may ask whether the WiFi master key is legal. Is it really safe? Of course it is legal and safe. WiFi master key is a member of the security agency under the Ministry of Industry and Information Technology.

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 to share hot spots. In short, users share their passwords to the cloud through the master key, and then if others meet the hot spots you share, they can connect with the master key. 2. The master key can only unlock the pure digital password. As mentioned above, the shared password can only be unlocked. Because the shared password can be arbitrary and varied. No matter numbers, symbols, English, case. As long as you have shared it and have a blue key after one-click query, you can unlock it. 3, connected to wifi, you can definitely surf the Internet. Not necessarily. Not every hot spot can go online. Some hotspots, such as CMCC, need mobile phone authentication to surf the Internet normally, some are connected with routers, but the owner is not connected with the network cable, or the network is busy.

4, the updated version can't understand the hot spots, and downloading the old version can solve it! What I want to tell you is that no matter which version of the master key is used, the cloud database is the same. If the version you are using can't be solved, then other versions can't be solved. So don't spend traffic downloading various versions. Because the master key database changes every day, new hotspots are shared every day, and naturally there are some invalid hotspots. Or the owner of wifi canceled the sharing of hotspots. Therefore, it is recommended that you back up the hotspots, either in your own mobile phone with the wifi connection manager or in the cloud with the master key, just in case!

Cracking is a technical activity, which requires a lot of resources and time. Basically, it usually takes more than 2 or 3 hours to crack. Imagine that so many hot spots can be cracked. In addition, it is illegal to crack the wifi password. It is impossible for an enterprise to do such a thing.

The sources of wifi hotspots of wifi master key are basically hotspots shared by hotspot owners, hotspots cooperated with merchants and wifi hotspots built by wifi master key itself. This mode is actually that everyone is for me, and I am for everyone, going out to use the wifi shared by others. Similarly, if my network bandwidth is sufficient, I can share it. I feel that many people swear that their network has been shared while using the network shared by others through the wifi master key. You can choose to "share" or "cancel hotspot sharing" in the background. The wifi master key provides you with an optional channel to connect to wifi.

Can't! First of all, we must understand the principle of master key cracking: master key cracking means that a large number of users use this software, and then get the permission of the mobile phone. The WIFI password entered by the user will enter the password library. After there are a large number of passwords in the password library, when you encounter a new WIFI, try to use the passwords in the library one by one! The process is so simple! So once there is a password that no one has used, or no user has uploaded it, that is to say, this password can't be found in the password database, so there is no way to crack it!

At present, the most commonly used master key on the market is the following.

This software has a large number of users and a larger natural password library, so it is easy to crack WIFI. This is not an advertisement, but the strength of others is there.

I hope my answer can help you. Thank you.
