Any way to hide CPU info from Whonix?

Hello. Usage of Whonix does hide the GPU name but doesn’t hide the CPU name and vendor. Is it possible to hide hardware from Whonix in order to make it more secure and decrease fingerprinting?

Yeah you can run it under QEMU full emulation mode if you can put up with the slow perf. No official support however:


Thanks, I will try it. But in practice, can destination website see the hardware information using remote JavaScript code or hardware info leak is only possible when Whonix Workstation is compromised?

Prerequisite reading, partially already answered on same link https://www.whonix.org/wiki/Security-misc#Restrict_Hardware_Information_to_Root.

CPUID is a mess and I don’t think there is any method to curb it.

Then then I found this cpuid x86 in JavaScript. but didn’t look into further.

Speculation: even if using https://www.whonix.org/wiki/Security-misc#Restrict_Hardware_Information_to_Root (or maybe even QEMU) it might still be possible to benchmark the browser to guess what hardware is being used and/or to fingerprint the browser. Using JavaScript. Or perhaps even without. For Tor Browser specific questions, I recommend, there is likely better information from Tor Project as per https://www.whonix.org/wiki/Free_Support_Principle.


They can perhaps get some idea by benchmarking your CPU with JS.
