VPN:

At a general level, a VPN operates by intentionally changing a user’s IP address to create the impression that they are situated in another country. This action reroutes the user’s data and traffic through the VPN rather than directly from the website to their device. Furthermore, numerous VPN services allow users to select their preferred VPN location, whether it be within their own country or in a completely different one. Also read how to detect VPN IP

USES OF VPN:

People utilize VPNs for a variety of reasons, with some of the most prevalent motivations centered around enhancing data privacy and security. This includes safeguarding personal information when connecting to unsecured public WiFi networks, shielding privacy from apps and websites seeking to track user activities, and providing reassurance for remote work scenarios, whether as an employee or employer.

MISUSES BY USING VPN

VPNs are frequently employed by online users to enhance their privacy and safeguard their data when surfing the internet for different reasons. Nevertheless, while VPNs offer increased privacy and security, they have also made it easier for cyber criminals to engage in unlawful and deceitful activities.

Database Validation:

A strategy to detect VPN usage in web browsers involves using IP address databases, which hold information about IP addresses and their connections to known VPN or proxy services. By comparing a user’s IP address with entries in these databases, it’s possible to determine if they are using a VPN or proxy service.While services like MaxMind, Udger, and IPinfo are widely used for their accuracy and extensive databases, this approach may not be suitable for detecting private self-hosted or corporate VPNs. Moreover, privacy concerns arise as users may be uncomfortable with their IP addresses being queried against these databases without explicit consent, and there’s a risk of data disclosure or misuse.

Time Zone Mismatch:

Time zone mismatch detection is another technique for identifying VPN use, leveraging the web browser API to display the local time zone based on device location or system settings. When a user connects to a VPN server in a different geographic region, a discrepancy may arise between the browser’s displayed time zone and the IP address’s geographic area. However, this method can be circumvented by simply adjusting the time zone in system settings. Implementing logic to detect impossible travel, where IP addresses change between distant regions in a short period, can enhance the accuracy of time zone mismatch detection.

Transmission Control Protocol (TCP)/IP Detection:

Analyzing TCP and IP packets is a longstanding yet effective method for VPN detection. By examining connection attributes across network layers, it’s possible to infer device properties such as operating system type and version, network configuration, and more. Utilities are available to aid in implementing these techniques effectively.

VPN detection helps businesses identify visitors, enhancing security by verifying identities and mitigating fraud and unauthorized access.
