Public bug-reporting pad:

https://pad.riseup.net/p/tor-anti-censorship-bugs-keep <-- we have anonymous tickets handling now. Let's see which anti-censorship repos to include.

== Announcements ==

The Cure53 security audit of Turbo Tunnel is over.

https://gitlab.torproject.org/tpo/anti-censorship/pluggable-transports/snowf... is a resource leak found by the audit.

David is waiting on an upstream disclosure before publishing the report, but there is nothing much to worry about regarding Snowflake.

== Discussion ==

Snowflake in Tor Browser 10.5 stable (mid June)?

Conclusion: yes, we're going to plan to ship Snowflake enabled in Tor Browser 10.5. There are a list of things we should make sure we're in a good position to monitor so we can know how it's going. And we might shoot for a 'soft launch', i.e. put it in but ask the comms team to not make such a big deal out of it quite yet.

== Actions ==

== Interesting links ==

https://gitlab.torproject.org/cohosh/censorship-analysis/-/blob/belarus/bela...

== Reading group ==

We will discuss "Domain Shadowing: Leveraging Content Delivery Networks for Robust Blocking-Resistant Communications" on April 29th

https://www.usenix.org/system/files/sec21fall-wei.pdf

Questions to ask and goals to have:

What aspects of the paper are questionable?

Are there immediate actions we can take based on this work?

Are there long-term actions we can take based on this work?

Is there future work that we want to call out, in hopes that others will pick it up?
