Free WiFi is everywhere these days, but to save data, you need to be careful when connecting to WiFi. If you connect to "phishing WiFi", your personal information such as bank cards, network account passwords, etc. may be stolen. In order to prevent these situations from happening, wifi jammer is also created.
An introductory video about "hackers hiding five-star hotel WiFi" once went viral. According to the video, when you're on vacation in a hotel, you'll see various WiFi settings with very similar names that you can connect to the internet at any time. And there's a hidden "phishing WiFi" in there.
These so-called "fake WiFi," or what we often call "fishing WiFi," are most often found in hotels, airports, tourist attractions, shopping malls, and buses, with hotels topping the list.
By building a fake WiFi network, once someone connects, hackers can monitor your online activity in real-time and steal personal information such as email account passwords, bank card payment passwords, and more. This is rarely noticed.
Mr. Huang from Guangdong said that when he was staying in a hotel in Quanzhou earlier, after searching, he found two WiFi networks with similar names, one with a password and one without. He chose the one with the strongest signal and no password. Connect your phone and computer. As a result, he was woken up in the middle of the night by a text message on his phone. Someone has logged into your Alipay and has already transferred hundreds of dollars to your bank card. Later I learned that the WiFi I connected to was not the hotel WiFi, but the fishing WiFi.
Another netizen, Cheng Yufei, said that he used free WiFi to buy takeout at the hotel, but later found that the money in Tenpay had been transferred twice. A similar situation was exposed earlier on CCTV's 315 gala. At the time, engineers from CCTV and a cybersecurity firm exposed some of the tricky aspects of WiFi phishing. The test subjects' mobile devices only need to be connected to WiFi phishing and privacy photos, bank card passwords and social software. Password and email password hackers on your phone can gain access to the data.
After using the wifi signal jammer, it can quickly and effectively help you avoid mobile phones, computers, and other electronic devices from automatically connecting to some fraudulent wifi.
