Convenient for life but exposed privacy, smart home, safer

A few clicks on the phone screen can turn on the TV, sweep the floor, wash the dishes... The emergence of the Internet of Things makes smart homes bring convenience to life. However, more and more news about smart homes leaking privacy and hacking has made people look at the hidden dangers of smart homes. What harm will users bring about neglecting security? How do we protect privacy and avoid these risks when we use it?

Camera screen is uploaded

Sweeping robot was invaded

In November last year, Cui Zihao, the owner of Qujiang Rose Garden, installed a Xiaomi smart camera in the living room. "The child is more than one year old, and my mother and I are returning to work. Usually, the babysitter is wearing the baby during the day, we bought it. A camera." The camera's picture can be seen on the mobile phone through the Xiaomi APP. The original intention of Cui Zihao is to view the situation of the children at home. Who knows that last year's news made him tremble.

"After 360 drops live uploading user video, it really feels scared." Originally it was a convenient smart device for users, but it became a means of obtaining illegal benefits. Cui Zihao said that if criminals use their own cameras to check the situation at home. After that, theft was carried out at no time in the family, and the consequences were unimaginable.

In fact, Cui Zihao’s concern is not worrying. Lu Ting, a citizen working in the joint venture, also likes to try new things. He has purchased a lot of smart home equipment at home. “Curtains, TVs, air conditioners, sweeping robots, all of which can be operated by mobile phones.” At first, Lu Ting enjoyed such a convenient new technology. However, not long ago, Lu Ting suddenly discovered that the sweeping robot often opened automatically, so that the friends who learned the programming came to see it. The other party said that the background was hacked, although they did not know the purpose of the other party. However, such an invasion is enough for the other party to obtain Lu Ting's personal information on the APP. In the end, Lu Ting had to cancel the registration through the brand customer service and re-install the registration.

Post-invasion privacy leaks into industry

Crack difficulty, low profit

For many people, the technological innovation and lifestyle changes brought by smart homes are far more important than the dangers behind them, which is why users ignore the safety of smart homes.

Wang Ruijun, an embedded engineer of Zhijiang Technology Co., Ltd., told reporters that smart homes such as sweeping robots, smart TVs and TV boxes that are widely used today are likely to cause user privacy leaks if hacked, if the user’s control terminal is also bound Bank cards, payment accounts, etc., will become the targets of criminals. The smart camera is also one of the targets of criminals. Wang Ruijun said that such incidents are not uncommon. The background structure of smart cameras is very difficult to crack, and the user usage is high. The information obtained is rich and it is easy to become the first choice for hacking. . "And this use of intrusion into the background to gain user privacy has become an industry chain."

There are also users asking questions, why are these smart home safety factors entering the home so low? The reporter asked Xu Huan, a software engineer of Xi'an Junde Technology, who had previously worked on smart home research and development. He said that the smart homes on the market today are based on the network control of the home and home appliances. The program setting is not complicated. To achieve a high level of security, you need to encrypt the key of the product, which requires a lot of labor and time costs for the manufacturer. Xu Huan said that in fact, many smart home security problems are not troublesome to solve, but manufacturers have grasped the psychology that consumers only pay attention to innovation and convenience, so the escalation of security threats of smart products has become the norm. Moreover, the upgrade and patch maintenance of many smart home products are lagging behind. The means of hacking the Internet of Things is no different from attacking the Internet. However, due to the weak defense system, the intrusion of Internet of Things is often simpler than the Internet.

Choose big brand products

Improve security with settings

As the development trend of smart life in the future, the wide application of smart home is only a matter of time. How to use these smart products safely? Xu Huan said that we must first choose the products of regular manufacturers and big brands.

“Now the brands of smart home products such as Midea, Haier and Xiaomi have their own measures in terms of safety.” Xu Huan introduced that the Internet of Things security system currently used by Haier is independently developed and has the same security mechanism as the Internet. It also ensures the security of CPU, after-sales, information exchange, and keys. In addition, some manufacturers have adopted a number of dynamic key encryption technologies, and the commands issued by users are encrypted and protected, which increases the difficulty of cracking.

In addition to the source of the manufacturer, users should also know relevant knowledge and reduce risks when using it. Wang Ruijun reminded that the use of smart home appliances requires the basic support of the router, and the router is also one of the channels for hackers to start. Therefore, users must pay attention to the use of the most advanced wireless encryption when setting up the router, while hiding the SSID and not broadcasting. . In addition, the firewall is enabled to periodically check the client list for other users. To prevent other devices from accessing, MAC address filtering can be enabled. For users with universal keys and other software on the mobile phone, wireless network is not allowed. At the same time, you can't take it lightly when using the product, such as computer, camera, etc., you must turn off the power when you don't need it, and don't install it in the bedroom, bathroom, etc. At the same time, it is best to find an object coordinate in a fixed viewing angle and check regularly. Angled offset to avoid privacy leaks. Wang Ruijun also suggested that users should not be too simple when setting the password of smart home. It is best to change the default port to an unused port and upgrade the firmware in time to improve Acrylic Anti Blue Light Filter, Blue Light Screen Protectors, Blue Light Filter For Pc, Anti Blue Light Filter
