Interactive check - Language (locale settings) - how it can be leaked

 

On our website http://ipleak.com you can check whether the information about your locale settings — the list of active languages, browser language preferences, and some others — can be leaking.

 

How locale settings leaks may occur?

Information leaks can occur through the browser HTTP headers, JavaScript, and plug-ins like Java or Flash, as well as through certain techniques of TCP/IP stack packet analysis like p0f. (A data packet, IP packet, or simply “packet” is a small, individual piece of data sent over the network between a browser and a server.)

 

You can check for information leaks on our website:

  1. HTTP headers — see the HTTP headers your browser sends.

  2. JavaScript — see what data about your system may be accessed through JavaScript.

  3. Java — see the data sent through your Java plug-in.

  4. Adobe Flash — see the data your Flash plug-in sends.

  5. Proxy / VPN Detection (MTU/MSS/p0f) — check what passive packet listening may reveal about your system.

 

How to get protected:

  • The HTTP headers your browser send can be edited using special extensions.

  • Disable JavaScript or use a browser extension to configure a list of trusted websites where running JavaScript is allowed.

  • Disable or remove Java and Flash plugins.

  • Your network interface settings can be modified to protect against fingerprinting techniques related to passive packet listening (p0f).
