In particular, by encrypting your data and hiding your IP address from the public, a VPN protects and secures your internet connection. To achieve this, a VPN server has a process to follow, such as:● using a connection protocol to securely connect a device to a server and an encryption cipher to encrypt the data traveling to it
● decrypting the data when it arrives at the VPN server and connecting it to the website on the user's behalf
● gathering the requested information from the website, encrypting it and sending it back to the user's device
● decrypting the information to allow the website to be displayed on the user's browser.A hacker can break into a VPN service by compromising any one of these processes by means of a brute force attack. It is easy to try this on a free VPN server, but a premium VPN service will have stronger security features and may be difficult to compromise.
Other ways to hack into a VPN service include:● vulnerabilities in the VPN protocols, if it fails to establish a secure connection between your device and the VPN server
● a cryptographic attack if it's not updated to the latest advances in computing. Older hash functions, such as SHA-1, and encryption ciphers, such as Blowfish, can be easily hacked
● by misconfiguring the VPN server if it is not secured with a stronger password
● by stealing the encryption keys used to secure the user's data.Before subscribing to a VPN service, every VPN user is advised to review the terms and conditions of the VPN provider and its security features.
