Hello, I often use trains, and now my favorite Amtrak train tells the newspaper that they will equip all trains with free public Wi-Fi by the end of summer. I am not an expert on PCs and all these gadgets. I just want to know whether it is safe to use these public hotspots. I need my personal data to be safe. In order to prevent this wifi from leaking your information, you can use a bluetooth jammers to block .
Public Wi-Fi hotspots are dangerous. We have already written a lot about this on the jammer-shop.com personal security blog, and we will explain why. First of all, all the data you exchange with the hotspot is sent via a radio signal with a frequency of 2,4 GHz. As you know, without Wi-Fi signal jammers or Faraday cages, you will not be able to limit the propagation of these signals. As long as the reading of the signal is not restricted, anyone within the Wi-Fi working range will be able to intercept your traffic and obtain some sensitive information.
Second, Wi-Fi is vulnerable to hacker attacks. Therefore, hackers will be able to use Wi-Fi vulnerabilities (such as weak encryption protocols or open SSID broadcasts) to invade the network. For example, if the hotspot uses WEP encryption, it will take at least 10 minutes to crack the network; if it is WPA2, it will take time-hackers only have a chance to crack it when someone is connected to the network.
So, we at jammer-shop.com may tell you that if you don’t plan to read emails or access bank accounts, using those public Wi-Fi hotspots is not dangerous. Otherwise, you may lose some sensitive data. We also recommend that you read our secure mobile banking article. If you are using your mobile phone to access your bank account, these rules will definitely help.
