Hackers and third parties will only be able to see the IP address of the remote VPN.
When you download and enable a VPN prior to browsing, a VPN can offer online privacy and increased security by helping hide your online identity and encrypting your traffic. Your Internet Service Provider (ISP), the government, and other third parties can track what you search, visit, and download.Įven if you use a private browsing mode, your IP address can still be collected. Whether you’re searching something online or communicating via social media, you’re leaving digital footprints in the form of your browsing history, cookies, and cached data. Although you always run a certain amount of risk when connecting to a public Wi-Fi hotspot, there are certain measures you can take to protect against attackers.A virtual private network (VPN) can hide a user's internal protocol address (IP address) and block their location and browser history, allowing them to share and receive information on public internet networks more privately. Even though technically there is no connection between the public Wi-Fi network and a user’s home network (i.e., different SSIDs and IP addresses), there is still the concern that a hacker can connect to a network hosted on the user’s device and exploit any potential vulnerabilities. Some network operators like Verizon enable users to more securely access hotspots by obtaining credentials via a secure cellular network and then authenticating users to the access point, but this approach is currently limited to cellular network providers and has its own set of security concerns. To ensure secure communication, each user must obtain a unique PSK before connecting to an access point, which is simply too difficult for most public venues to manage.
As such, data can be passively collected from radio waves and then decrypted at a later point. While some venues do print out the PSK on a receipt so only patrons can use their Wi-Fi, it is still a shared key for all patrons. In fact, most venue access points will only display an end-user agreement (EULA) or advertisement before allowing users to connect to the Internet.
