Yes, the Tor Project is working on a sandboxed version of the Tor Browser that would isolate the Tor Browser from other processes of the operating scheme together with boundary its might to interact or question low-level APIs that tin Pb to the exposure of existent IP addresses, MAC addresses, figurer name, together with more.
Sandboxing is a safety machinery for separating running programs. When an application is sandboxed, its procedure runs inward a dissever surroundings from the underlying operating system, then that errors or safety issues inward that application tin non move leveraged to acquit upon other parts of the OS.
Sandbox applications are enabled inward their ain sequestered surface area together with memory, where they tin move worked on without posing whatsoever threat to other applications or the operating system.
Major modern browsers, including Chrome, Firefox, together with Edge, purpose sandboxed environments to dissever themselves from the operating system.
However, the Tor Browser, which itself is based on the open-source Mozilla Firefox browser, did non purpose the sandboxing surroundings that left the browser somewhat insecure fifty-fifty afterward then many privacy protection features.
Just rewind the FBI's 2015 investigation into tyke pornography site Playpen, inward which the way hacked into some 8,700 computers across 120 unlike countries.
The FBI used Tor exploits to position together with grab visitors of PlayPen hiding their existent identity using Tor. Such exploits targeting the Tor Browser tin likewise move used to unmask the identity of journalists, political dissidents, together with others.
Keeping this inward mind, the Tor Project started working on a Sandboxed version of the Tor Browser inward September this year.
The sentiment behind the motion is that exploits together with vulnerabilities targeting Tor Browser are trapped within the sandbox surroundings together with tin non become out together with acquit upon the residual of the figurer or unmask anyone.
Tor developers convey released the offset version of its novel together with improved Tor Browser, though the version is nevertheless real much an alpha; then i tin aspect bugs, some potentially major ones.
One of the developers working on the projection describes the browser features as:
- A Gtk+3 based UI for downloading/installing/updating Tor Browser, configuring tor, together with launching the sandboxed browser. Think `tor-browser-launcher`, that happens to run Tor Browser inward a bunch of containers.
- Linux seccomp-bpf + namespace based containers for Tor Browser, that attempts to prevent/mitigate exploits together with bring down the sum of personally identifiable data to a minimum, centered some bubblewrap (runtime dependency).
If y'all are to a greater extent than privacy conscious, y'all should purpose a Virtual Private Network (VPN) amongst Tor.
As I previously recommended, Privatoria VPN provides a number of bang-up features, including VPN, VPN Tor, Proxy, Proxy Tor, together with Anonymous Emails, which makes it i of the reliable VPN services available inward the market.
