There are three main ways to connect to someone's home wifi:

1, legging it to ask for the password.

2, use a Wi-Fi password cracking tool such as EWSA Pro to crack the Wi-Fi password.

3, use an app like Wi-Fi Master Key to get Wi-Fi passwords in your neighborhood.

Wait a minute? It's only been half a minute and we're done with Wi-Fi? Not yet. There are more benefits to come.

Let's analyze the pros and cons of the three ways.

1, legged to ask, if you do not have a high face value may be rejected oh.

2, the cracking time is long, it is likely to get cracked password before the Wi-Fi owner has changed the new password.

3, use an app like "Wi-Fi Master Key" to get the password of a nearby Wi-Fi.

The first thing to understand is why there are tons of Wi-Fi passwords available in "Wi-Fi Master Key" tools.

The Wi-Fi password software itself is a tool to get Wi-Fi passwords.

Getting the passwords of the WiFi that the user who installed the software has connected to is the first problem that WiFi Master Key needs to overcome, and after that, it can dig out 1-10 Wi-Fi IDs and Wi-Fi passwords from one user.

Many of the saved passwords are in plaintext or have only undergone a simple encryption operation, and the software can access them at will if the user has rooted his or her phone.

Apparently, WiFi Master Key has a cloud of its own that stores a lot of Wi-Fi information grabbed from users' phones.

Because of the public's extreme desire for fast Internet access, they happened to hear or see that there was such a magic tool, and downloaded it to their cell phones on the spot, and in the intervening two years, the software's user base has reached as many as 500 million.

When you open the software for the first time, you should have seen that it will ask you for a request to 'get location information' for two purposes, the first is to get the approximate location of your area.

Then it will cache all the WiFi information near the location to your client, which can greatly reduce the pressure on the server, and secondly, at present, WiFi Master Key will also do the promotion of some commodities/merchants, so it is convenient to get the location information for personalized placement.

1. Password Matching

Previously, cell phones didn't provide permission for it to get the Wi-Fi list, so the software would guide the user to take a screenshot of the WiFi list interface, and then get the WiFi name through picture analysis. And nowadays, iOS devices not only provide permission to get the neighboring WiFi list.

Initially, the software could only match by WiFi name, but now it can match using other information of WiFi such as (MAC address), which is a better match and avoid the password mismatch caused by the problem of Wi-Fi name duplication.

2. Crash database analysis

After having hundreds of millions of data, which can be regarded as really big data, it is natural to count and analyze the data, and get some commonly used weak passwords, such as eight 8s, four 123s, and eight 0s.

The people who understand the routing settings and WiFi settings were not many, and many door-to-door service masters usually just set the passwords as simple and memorable, which also greatly improves the success rate of bumping the bank.

For WiFi where you can't get the password, the software will undoubtedly make this attempt, which is low cost and still has a high success rate.

The dangers of crashing and being crashed.

If your home network is dinged by a white user, it's just a little slower when everyone's online at the same time, but if your home network is dinged by someone with hacker qualities, it's probably time to pay attention.

If you have WiFi at home, you must have a router, and the router's password is still the initial guest/admin, or you set it to six 8s.

If I were the attacker, I would think of all kinds of ways to get the password for your router, and if I got lucky enough to get in, my next step would be to set my router to my own computer's gateway. gateway set to my own computer, and then all sorts of interceptions and injections.

If you don't have a takedown router, you can also take advantage of the condition of being on a LAN, and lull white users into falling for it through various deceptive means such as *** enjoyment and webcasting, and there are always plenty of ways to do it.

As long as you open an opening, basically your cell phone/computer is controlled, poisoning, cheating, luring, etc., will be used as much as you can.

You don't have a Wi-Fi master key installed on your phone, and you don't tell the password to the next neighbor or passerby, and you find that your network is still being rubbed out. Why? It turns out that your relative came over last month, and then he had this software on his phone.

The best way to keep from getting caught in the crossfire is to not tell anyone your password, even if it's a relative. Today's routers can be set up with two Wi-Fi by default, and you can put a traffic limit on the sub-Wi-Fi.

Of course, some WiFi is done in a more sophisticated way, where you can monitor connected devices from your own phone and then set up whitelists and blacklists. But I don't think many people will use this kind of WiFi, and general Wi-Fi also supports controlling Internet-accessible devices from a web interface.

Another way is to change the SSID broadcast of the wireless settings to 'hidden' in the router, and there's no way for peripheral devices to find your home WiFi network.

If you really want to dabble, we suggest you use Wi-Fi password acquisition software to get the password on a device that doesn't have a saved Wi-Fi password, or use an EWSA Pro-type tool to get the password on your own, and don't try to install Wi-Fi password acquisition software on a device you use every day.
