Along with the continuous development of technology, Wi-Fi has become an indispensable tool in our lives - home, office, places of recreation and entertainment are also inseparable from it. But Wi-Fi technology is a double-edged sword: in addition to convenience, various security issues require our attention.
In 2022, many applications were introduced in China purporting to get "free Wi-Fi", security experts have installed - these applications pose a threat of leakage or theft of your data. Among such applications, "WiFi hacking master", "Radar WiFi" and "Yuebao WiFi Assistant" were mainly criticized.
Chinese free Wi-Fi software testers found that pop-ups with the words "Confirm" and "Open" that were clicked while connecting were advertising links in disguise.
After the user clicks the button without any prompts, the app in the sponsored link will be automatically installed on the phone. In the end, the free Wi-Fi that users wanted turned out to be useless, and the phone had a bunch of inexplicable apps.
To make matters worse, the engineers did more testing and found that this type of free WiFi app was still collecting a lot of user information in the background.
For example, an app called "WiFi Radar" collects the location information of test mobile phones 67,899 times in one day! what does it mean?
That is, users are constantly positioned from morning to night, including sleep, and the user's life trajectory, location, and even occupation and preferences will be exposed.
And after these applications are added, the phone will turn on periodically and various advertisements will automatically pop up.
In addition to stealing personal privacy, what hurts users more is that these “free Wi-Fi” apps can also use privacy leaks and background loopholes to steal money directly from mobile phone payment options.
Users in China may have the experience of simply browsing some websites on their mobile phones without leaving a phone number, only to receive harassing calls from related industries.
China Information Security Lab 3.15 found that after installing different apps on different versions of children's smartwatches, they can revoke various sensitive permissions such as positioning, address book, microphone, camera, etc. without user authorization. This means that they can easily obtain private information such as location, face images, recordings, etc. and may present security risks.
Since the "Personal Information Protection Law" came into force last November, it means that the protection of personal information in China has entered a new historical period. If users find that personal information has been leaked, they should immediately contact the party that provided the information to stop the breach, and if they find that their information has been illegally stolen or sold, they should also report it to the public security authorities
