Your personal experiment tells you how dangerous it is to get a free wifi from "bush."

On five long vacations, travellers travelling around the country “spread” wifi in order to reduce mobile phone traffic. A survey of public wifi hotspot safety in nine regions and cities around the world, by well-known security software company avis, shows that wifi users in asia are the most vulnerable to cyber attacks。
Is it a "free lunch" or a preset trap? What are the risks of winning? How can free wifi be used safer? Journalists have conducted research and personal experiences in this regard。
Use your tweets to send me messages -- easy
In recent times, some “celebrities” have come out of panic after issuing a controversial tweet, saying, “this is really not my tweet”. Do you believe it or not
But the journalist's own test found that if you get to the unbelievably wifi, it's not hard to get a message from your own microblogging。
It's a safe business in shanghai. The director of the security service lui yeung and the journalist made an experiment: the journalist posted a random tweet after using a tablet of processed black wifi. The technicians are then immediately able to use the journalist's microblogging for any content. Moreover, even if the technicians had posted information on the computer, the microblogging suffix still showed the tablets from journalists。
“for the general user, the most dangerous is this false wifi. If the french elements do not name wifi as an operator such as ccmc, chinnet, chinauicom, or other common names, the user may leak personal information as soon as he or she does not use the internet。
As the main commercial wifi supplier in china, al-maindi has installed over 40,000 commercial wifi throughout the country. With regard to the potential harm of black wifi, the cmo shahua sword tells reporters that the most dangerous situation with the blackwifi connection is that it pre-empts fishing sites, such as disguised payment pages, so that users may enter bank account information, even trade codes, and personal identity information, so that the information is leaked。
Over 99% of netting risks -- these techniques are rare
The “five ones” leave is coming, and the safe passage of wifi is a matter of concern to many. Data from cell phone housekeepers indicate that nearly half of the users are concerned about the safety of wifi。
Journalists consulted with a number of experts on the subject and found that they could avoid more than 99 per cent of the risk by acquiring the necessary skills。
The first thing is to choose wifi, so don't look up there. What kind of wifi is that? As a well-informed cyber-policeman, the shanghai public security bureau told reporters that normally regular wifi would alert you to enter a mobile phone number and text you, so that the internet would be relatively safe; it would be more alert to free wifi, which does not require any password to land directly, which could be a bait set by outlaws to allow users to access the internet free of charge and then re-inform their personal information。
Mjt informed journalists that there are three main types of connection scenes currently in public wifi security: sms authentication, 2d authentication and protocol certification, such as peace wifi, and wifi certification, and miphone protocol certification。
As the country's leading public transportation provider, cmo liu liu, a leading hotspot company, told journalists that connecting wifi through official app would also significantly improve safety, so as to filter out a large number of pseudonyms of wifi. Free wifi for the three main operators and public wifi for many cities have the corresponding apps, such as china's mobile wlan, shanghai's i-shanghai and the 16wifi。
In addition, every effort is made to avoid trading on public wifi. In particular, the experts cautioned that users should not connect to uncertified wifi and that even occasionally, there was no operation involving payment categories。
It's about basic security
While black wifi must be warned, it is clear that excessive fear for wifi's safety is also not scientific。
Many are most concerned not about black wifi, but about the destruction of their home wifi. In response, experts stated that it was more difficult to break through the wifi router, and that the greater risk was that wifi passwords were not too strong to be broken. Therefore, this risk can be effectively reduced by setting up high-intensity encryption and passwords for wifi。
Even black wifi, if it wasn't through a fishing website, it wouldn't be easy to get your personal information. The sword says that the protections for these applications, whether from the payment of treasures, micro-intelligence or online silver, are perfect and that their information is encrypted; it is not easy for the outlaws to find loopholes in these applications, even if they get them through black wifi。
As a result, a number of practitioners told journalists that for the vast majority of information leaks, wifi was a source of external concern, and that most of the security risks could be avoided provided that basic safety precautions were taken. Thus, while there are risks and safety precautions to be taken, it is possible to remain calm。
