[tor-talk] Tor Browser Custom Intro Page Fingerprintability

[bancfc at openmailbox.org]

AFAIK for trademark reasons TPO recommends that distros built around Tor 
Browser show a custom intro page upon Tor Browser start up to users 
(which we do in Whonix).

Is this custom page detectable by websites a user visits (with a 
malicious JS script for example)?

If successful this attack has the effect of partitioning Whonix TBB 
users and everyone else.
