The real reason why WiFi was smashed
Many people think that my home WiFi is always easily cracked by others, and it is because of router problems.
Here, route jun wants to say:
Give a chestnut
If the router's encryption mode is WPA-PSK/WPA2-PSK, the WiFi password is set to digital plus letters, and the length is more than 8 bits, as long as it is not too fool's 12345678, others are using a computer to crack your WiFi. The password must be cracked at least one day!
If you set the password longer and more complicated, the computer used to crack the WiFi password has crashed without estimating...
The most important thing is that you want to know that most of the people near your home have the same hacking level as you. Not many really know how to crack the WiFi password!!!
Most of the time, you are actually telling the Internet users what they are doing by "passing" their WiFi passwords!
A lot of people's maps are easy to install so-called WiFi master key / WiFi crack app, think it features Niubi, a minute to break the WiFi password Oh, wherever I go there can be WiFi!
As just said, it takes at least one day for someone else to use a computer to crack your WiFi password at least! How can a WiFi master key break such a complex password in less than a minute!
Xiao Bian just wanted to say: Out of the network, sooner or later are to be back!!!
There is no free lunch in the world. It is because you have smashed someone else's WiFi, which leads to the WiFi of your own home.
With everyone to popularize the work principle of WiFi master key:
The master key is not a crack password, but a shared password.
If your mobile phone has a WiFi master key installed, then the WiFi password you have previously stored in your phone will be secretly uploaded to a cloud database (this is equivalent to that you have already informed the world of the WiFi password), when someone nearby uses WiFi Master key to connect your home WiFi, it will go to this database to search for your home wifi name corresponding password, and use the password to connect your home WiFi, so your home's WiFi is so silently smashed !
Even if you haven't installed this APP, but happened to be at home last week to play WiFi connected to your home, it is more clever that his cell phone installed WiFi master key, and then your home Wi-Fi password to share out Now.
â€
Some people may say that the default sharing function of the Wi-Fi master key can be unchecked, and if not checked, the WiFi password will not be shared.
Even if it says that it hasn't been shared, how can ordinary people who cannot see source code at all know that it has shared it?
Knowing that there was a big god holding the same suspicion, he decompiled the Wi-Fi master key installation package. Some people said that there was no evidence that people stealing or invading privacy was defamatory and dirty, but the source code was not. Lying. Do you know why the Wi-Fi master key requires mobile root privileges? Because Android's mobile phone wireless account data is stored in a file, it is /data/misc/wifi/wpa_supplicant.conf. This is a system file. The file is inaccessible because of insufficient permissions. This file is extremely important. The file, or the ability to see the contents of this file, means that you can get all Wi-Fi hotspots that this phone has logged in with, as well as their clear text passwords!
After knowing that the god decompiled the Wi-Fi master key and released the source code, he wrote it in line 1051 of the source code:
Const-string v3, "cat/data/misc/wifi/wpa_supplicant.conf/data/data/com.snda.wifilocating/wifi.conf"
You can see that it not only accessed the wpa_supplicant.conf file but also copied it to its own cache directory.
In simple terms, even if you do not check "Auto Share", it will actively collect relevant data from the mobile phone with this app installed and upload it to the cloud database. Therefore, your home WiFi is doomed to be embarrassed.
The WiFi at home was crippled, causing a lot of major security risks in addition to the slow speed of the Internet.
If you are an individual user and someone else takes a Wifi password, your privacy may be exposed.
If it is a corporate user, someone else has taken the Wifi password, and the company secret may be exposed again.
Now that the Internet is getting stricter and stricter, people are using your home network to do something bad. When you check it out, it's your IP. You jump into the Yellow River and you can't clean it.
This year, lost a U disk, repair a computer, it is easy to become famous, was known that the WiFi password may also be famous!!!
OK, everyone is ready to take the big move (applause should be here).
Flood prevention network has a coup:
1. To change the password regularly, the password is preferably in the form of "case + English + number + special character". The more complex the better, (for fear of forgetting the best, take paper and pen to copy).
2. Can try to set the MAC address binding on the router, and now many high-end routers have black/white list and other security settings, such as AC15, AC9 has a blacklist function;
3. Hide the router's SSID so that others cannot find your home WiFi signal;
4. The most important thing is, please silently uninstall the so-called WiFi cracking software on your mobile phone.
5. If you have a friend who comes to your home and needs a WiFi connection, if you have such an APP, please uninstall it first.
6. Advise others not to install a cracked WiFi app.
