Tor Browser 10.0.18

Tor is one of the biggest open-source software, its networks have virtual tunnels that generally enable people and different groups to enhance their privacy and security on the Internet.

Recently Tor has released its Tor Browser 10.0.18, and the main motive of this release is to fix all the countless bugs, which also include a vulnerability that enables different websites to keep track of their users by fingerprinting the installed application.

We all know that Tor administers Internet traffic with the help of an overlay network that is free worldwide.

But, this network consists of nearly seven thousand relays, that help in concealing a user’s location as well as usage from people who are conducting network surveillance or traffic examination.


Scheme Flooding vulnerability

Scheme flooding is a vulnerability, that uses different custom URL schemes as an attack vector. According to the experts, this vulnerability generally enables the actors to identify that which applications have been installed by the users.

Once the experts identified the application successfully, then they use all the data and information of the installed app on the user’s computer. 

And the main motive of doing this is that they want to assign a permanent unique identifier in the user’s computer so that they can use the system even if the users switch browsers just by using incognito mode or a VPN.

Not only this but scheme flooding also allows third-party tracking in a different browser. However, this exploit generally helps the hackers to track down the usage of users’ browsers like Google Chrome, Safari, even the Tor browser as well.
