Speaking of this WiFi master key, many people must be familiar with it, and they may have used it or are using it. The official introduction uses a bunch of new concepts:
"World Wide Web * * * enjoys the platform, based on the mode of * * * enjoying the economy, through cloud computing and big data technology, using idle WiFi resources shared by hotspot owners to provide users with free, stable and safe Internet access services."
In fact, it is a tool that allows you to connect various WiFi hotspots without knowing the password. To put it bluntly, it is "for surfing the Internet".
How powerful is the so-called "master key"? In the "Economic Half-hour" broadcast on the 28th, the reporter made an attempt. With a mobile phone with a WiFi master key, he went to residential areas, shopping malls and restaurants, successfully connected hot spots without pressure, and even entered the routing background of a family.
You said that residents and businesses may not have a strong sense of safety, so let's challenge the difficult ones again. The reporter came to a branch of Bank of China, and boy, it was successfully connected again. Note that it is not the WiFi that the bank business hall is open to customers, but the network of other office departments within the bank.
The insurance company's WiFi network has not been spared. The reporter stood at the entrance of China People's Property Insurance Co., Ltd. Beijing Branch, and the software showed that there were at least six connection hotspots. In Lujiazui, Shanghai CBD, the encrypted WiFi of financial institutions, including Bank of East Asia and Hai Yin Finance, has become a free network that can be connected at will in the WiFi master key.
What's more, the WiFi master key didn't even let go of the network of the Ministry of Foreign Affairs, and the reporter got on the WiFi of the Ministry of Foreign Affairs at home without any trouble. The Shanghai Municipal People's Government, China Inspection and Quarantine Department and other government agencies were also attacked by hackers ... This master key is indeed "universal".
Together with the WiFi master key, there is also an application called "Wi-Fi Key", which is more powerful. In addition to cracking the WiFi login password, you can also view the plaintext password directly with root permission on your mobile phone.
There is no free lunch in the world, and the WiFi master key provides users with various Internet access passwords for free. Obviously not for charity, then how do they make money?
I have to admit that although surfing the Internet is disgraceful, it is indeed a universal demand. WiFi master key captures people's psychology and attracts a large number of users by providing internet access function. Officials claim that the number of users has exceeded 900 million. With traffic, the simplest way to realize it is advertising.
In the program, the reporter contacted the advertising agent of the WiFi master key. The other party can accept any advertisement: gambling or pornography, and the money is in place. There are no advertisements that cannot appear on the WiFi master key.
After the program was broadcast, the WiFi master key quickly came out to clarify, mainly for three points:
We are not "stealing passwords", but providing users with convenient internet access through "sharing resources";
The "Wi-Fi key" appearing in the program is actually a cottage. In recent years, the WiFi master key has become famous, and there are too many popular apps.
Intensify efforts to investigate and deal with non-WiFi hotspot owners sharing. By the way, sharing hotspots pays off, and we have provided WiFi owners with returns worth more than 65.438 billion yuan.
However, this explanation is not convincing. First of all, if the app does not actively prompt the user to log in, it is regarded as agreeing to the user agreement, and the hotspot will be automatically shared to the network; Secondly, the statement said that we should investigate and deal with the sharing of non-hot owners, but what is the basis for judging whether it is a hot owner? Enter the password of the router background account? Or upload SSID and MAC address?
When it comes to uploading SSID and MAC address, it is necessary to submit information when canceling hotspot sharing operation. The previous version will upload photos of the appearance of the back of the router, but it is obviously not safe to give such important information to a third party. Even WiFi passwords can be shared without the owner's consent. How can we ensure that router information will not be used for other purposes?
By the way, we tested the WiFi master key of the iOS version, and I don't know if it is because of the system permissions that the connection failed all the time, and there is no entrance to cancel hotspot sharing like the Android version.
In the Android version, when you apply to cancel hotspot sharing, the page will also prompt you to suggest changing your password to prevent others from accessing it. But the problem is that after the password is changed, once the WiFi master key is installed on the mobile phone using the network, the new password will still be uploaded to the server. Is there a difference between changing and not changing?
Having said that, what is this WiFi master key? Official website shows that its owner is "Shanghai Lianshang Network", which belongs to the startup company of Zhangmen Technology Group, and its CEO is Chen Danian. Of course, he is better known as Chen Tianqiao's younger brother and one of the founders of Shanda Network.
