The use of wireless WiFi networks has now become very common. Many users think about the security of their networks and computers, sometimes they have questions, how to hack WiFi, how real is this threat?

In this article, I propose to ordinary users, perhaps far from the security audit questions of wireless WiFi networks, to look at their WiFi network through the eyes of a hacker, and even to wonder how to hack WiFi ?
Although the material is further described as simple as possible, we cannot do without concepts specific to the WiFi audit.

How to crack wifi password using brute force

Overview of brute force

1. The exhaustive method is a method of deciphering a password. This method is very similar to the mathematical “complete induction” and has been widely used in cryptanalysis. Simply put, the password is calculated one by one until the real password is found. For example, a four-digit and all numbers consist of a total of 10,000 combinations of passwords, which means that we will try up to 9999 times to find the real password. Using this method, we can use the computer to calculate one by one, which means that it is only a matter of time to crack any password.
2. Of course, if you decipher a password that has 8 digits and may have uppercase and lowercase letters, numbers, and symbols, you may use a few months or more to calculate a common home computer. The combination may be several trillions. Combination. Such a long time is obviously unacceptable. The solution is to use a dictionary. The so-called “dictionary” is to lock a certain range of passwords, such as English words and birthday numbers. All English words are only about 100,000, which can greatly reduce the password range, which is greatly shortened. Deciphering time
