Introduction: wi-fi is an essential communication tool in our lives. Asking about the wi-fi password has now become the first thing for most users to go to a new location, but most do not have a relevant awareness of wi-fi security. According to statistics, we now have close to 600 million mobile phone users and, with the soundness and rapid growth of mobile networks, mobile terminals, such as mobile phones, have become the first option for most internet users to access wi-fi, while connecting wi-fi to the network at any time and anywhere, thus saving users the trouble caused by mobile phone traffic. But people tend to ignore wi-fiCybersecurityThe importance of the wi-fi network, which is automatically connected on a daily basis, can also be an export for personal privacy。

This year's 3. 15th party mentioned the safety of the wi-fi network, while the false free-of-charge public wi-fi hotspot was targeted, pushed to the tip of the air, and the security of the local area network closed-off alerted users, individualsPrivacy protectionThe time has come. However, the same problems and safety risks arise when it comes to free wi-fi products。
I. Security risks to the exposure of free wi-fi products
In recent days, the viewing of the live news has exposed cases such as wi-fi's universal key, a free-of-charge wi-fi “wi-wi-wi-wi-fi” device, which leaks the privacy of wi-fi users。
Lbe security master, safety engineer, details
There are currently many similar “wi-fi filters” in the market for application, and the wi-fi universal key is one of the more famous products that can help users connect to nearby wi-fi hotspots without knowing the password for the purpose of doing so. According to fong jin-woo, a technical expert in lbe security, the principle that products such as wi-fi's canal key can achieve nettling is suspected of leaking, as such applications share user passwords silently and in their use they are not detected at all. The use of free wi-fi products (wi-fi appliances) is therefore fraught with security risks and risks of personal privacy leakage。
Users found no reason to be rinsed at home
Ms. Sang in beijing was confronted with such problems, and it was confusing for a monk to find her family's network particularly slow, after various obstacles, because her home wi-fi had been sprawled, although her password was difficult, she had not used free wi-fi products, and her home wi-fi had been razed by others. Just in the middle of the day, the technicians asked sang-sang to think about whether she had friends who had installed such products and connected her house to wi-fi, which reminds her of the wi-fi key she had installed when she helped her aunt cook at home。
This also means that as long as a product like wi-fi is installed, it will automatically share your password as you connect wi-fi. More worryingly, if hackers use such products to connect to users wi-fi, they can randomly monitor, attack and intercept users' bank card information, posing a great threat to their privacy。
Go to the inside of the enterprise and view the files
Moreover, if hackers attack the enterprise wi-fi, they pose a serious threat to the business privacy of the enterprise and cause huge economic losses to the enterprise. Fan jin-woo, a technical expert in lbe security, demonstrated on site how to access enterprise privacy files using wi-fi's universal key and simple tools to access the enterprise's internal local area network。
Although products such as wi-fi's altruistic key have recently been subjected to pressure from public opinion to modify some of the tort set-up and functions, such applications, due to their long-term build-up, have a large user community and cannot avoid security problems。
Ii. Detailed information on the wi-fi leak
In response to the security risks and privacy leaks associated with the false free public wi-fi and wi-fi's products, the lbe security master ceo zhang yong was specially connected。
In response, zhang yong said that wi-fi, as an entry point to the mobile network, has three problems for users:
1. Information security issues at the user level (impacting users: false free public wi-fi hot spots, free wi-fi products)
As described during the 315th evening, the false and free public wi-fi hotspots pose a significant threat to the privacy and security of users and can randomly intercept messages sent by users. The same is true for free wi-fi products, where hackers can still intercept user information。
Lan security at the wi-fi owner level (impact users: free wi-fi products)
The password is the gateway to the closed ring of the home-based wi-fi network, and today there are not a few users using the home-based nas and home-based smart hardware, and more users will use the local area network (lan) sharing function, but most users have little idea of lan security. Hackers, after acquiring their home wi-fi passwords, are free to connect and attack the wi-fi network, which is often invisible to the wi-fi owner at first sight, posing a serious threat to personal privacy security and to lan users。
3. Business safety at the enterprise level (impact users: free wi-fi products)
Businesses usually have their own wi-fi, as well as their own user wi-fi, while many enterprises have a significant number of shared documents available on the lan for their employees or visitors. When visitors or employees use a free wi-fi product, the enterprise's wi-fi password is leaked, which poses a threat to the enterprise's information security and, more importantly, to its business privacy security。
In cases such as false free wi-fi hotspots, users can prevent privacy leaks if they do not do so undisclosedly. In the case of free wi-fi products, such as the wi-fi master key, care must be taken to avoid unnecessary influence on friends or companies around them for the sake of network users. For wi-fi owners, password security is ensured, passwords are regularly modified, and users of some network knowledge can be reduced by adding wireless filters and concealing wireless networks。
If a user is concerned that the wi-fi password has been leaked, the latest version of the lbe security master can be used to conduct a wi-fi password security check to check if there has been a leak of his wi-fi password, and, if the wi-fi password has been leaked, the user is advised to change the password immediately or to remind the wi-fi owner to change the password in order to avoid possible privacy problems。
