The day before, Wi-Fi manneungyulsoi released "Wi-Fi" China public security report 2017. The report shows that in the number of Wi-Fi, there are more than three or four line cities in the city of first and second line. Among them, Chengdu, Shenzhen, Beijing, Guangzhou and Shanghai are listed as the hotspots of Wi-Fi hot spots in Chinese cities TOP 5.
However, from the proportion of risk Wi-Fi, the proportion of the first and second line risk Wi-Fi is far below the three line cities. Therefore, both in quantity and in security, the advantages of the second line cities are obvious.
Among the provinces in China, Guangdong province has the largest number of hot spots, followed by Zhejiang and Sichuan provinces. It is worth noting that the number of Wi-Fi hot spots in Guangdong is also the highest in the total amount of hot spots in the country.
According to the Wi-Fi universal key safety data statistics, the number of hot spots in the country in 2017 accounted for 0.8295% of the total hot spots.
According to different safety indicators, the report defines the risk hotspots as three different levels of high school low. Most of the risk hotspots are low risk hot spots which do not cause significant harm to users, accounting for 0.8185%, while the median risk hotspots are only 0.0019%, and the proportion of high-risk high-risk hot spots is 0.0091%.
When users are inadvertently exposed to the risk of middle risk, the behavior of the Internet will be disturbed. For example, a user enters a Taobao page, but it may be directed to other sites or not to open a Taobao. However, as long as users pay more attention and improve their awareness of prevention, the hot risk of middle risk can not cause serious loss.
In the past, there was a general concern about the security of online payment behavior after connecting to Wi-Fi. Some users believe that once the payment software is used in the risk Wi-Fi environment, personal account information will fall into the hacker's hands, and even account for property theft such as account theft, credit card theft and so on. Security experts say this is not the case, which is a misunderstanding that users do not know enough about the banking system.
The law, all the bank's online payment software and compliance of third party payment platform in the core data exchange must adopt bidirectional encryption communication, such as App, Alipay, WeChat, bank payment and other payment platforms have been strictly enforced, this means that even if the encrypted communications traffic was hijacked, the attacker is almost impossible to encrypt data for the interpretation or tampering.
Therefore, users pay regular payment software, the attacker only by Wi-Fi single channel, steal user account password are rare. Most of the cases of user bank card being stolen are mostly due to the fact that users have entered the phishing website without being aware of it, and have entered personal account information on fishing pages, or mobile phones and computers themselves have been poisoned.
Of the 0.8295% risk hotspots, the food and beverage food scene has the highest proportion of risk hot spots, accounting for 35% of all risk hot spots. The food was assailed.
By contrast, the number of risk hotspots from Gaestgiveriet Hotel is only 11% of all risk hotspots, so we can see that the safety of the whole Wi-Fi is high.
In addition, the proportion of the risk hot spots in the scene of leisure and entertainment and life service is 12%, and the users should pay attention to it.
Security experts suggest:
1, use big brand, big manufacturer's router, avoid brushes third party firmware at random;
2, do not Root Android mobile phone as far as possible, the apple mobile phone do not escape from prison;
3. It is more secure to use professional networking software to connect the public Wi-Fi.
4, screening whether it is a hot spot of the mountain village, select the hot spot with the official certification mechanism to connect;
5, try to use the official App for online shopping or payment.
6, close the Wi-Fi automatic connection function of the mobile phone, and avoid the risk hot spot without the password.
