Some very interesting research and practical attacks that build on the "Hot or Not" clock skew paper. The researcher (Ethan White) proposes some effective countermeasures for TAILS and Whonix deployment.
This ticket is for tracking this development.
IMHO this fix should not be optional. We should always deploy safer defaults whenever possible to meet users' expectations that Whonix protects them from advanced attacks.
