@mray @cwebber would love to know as well.

For people not in the know, @librecast is a R&D initiative that's innovating the internet stack with support of @NGIZero and @nlnet

First, to enable #multicast on the unicast internet an overlay network is planned, based on #WebRTC. See:

librecast.net/librecast-strate

#Librecast LIVE will bring all the technology together, to demonstrate and be a reference implementation. With #ActivityPub support being planned. See:

librecast.net/live.html

#Meta opracowała system "localhost tracking", który omija zabezpieczenia #Androida, śledząc użytkowników nawet w trybie incognito, z włączonym #VPN i usuniętymi ciasteczkami.
#Aplikacja działa w tle, nasłuchując na portach lokalnych.
Na stronach internetowych przesyła identyfikator _fbp do aplikacji przez #WebRTC.
#Dane (m.in. odwiedzane strony, zakupy) są łączone z kontem użytkownika, nawet jeśli nie logował się w przeglądarce.
Kogo dotyczy problem?

Continued thread

Both #Yandex and #Meta used obfuscation techniques to hide that the traffic occured and/or that the apps were listening to these requests:

➡️ Meta traffic was using #WebRTC, which does not show up in the browser's developer tools
➡️ Yandex traffic looked non-local
➡️ Yandex apps started listening only after several days

BTW: Apparently, Meta stopped doing this yesterday. But they probably still have the mapping DB.
All the details by the researchers here.

Staggering how far #Meta will go to de-anonymise users.

I was actually surprised it took so long because this is not a new loophole. We discussed this issue almost 10 years ago in a different context: #WebRTC allows to circumvent the secure origin policy.

I made a PoC back then

lgrahl.de/examples/dc/webrtc-c

which still works to this day. It is also hard to prevent because the PoC doesn't do anything that is forbidden. It leverages a currently essential part of the STUN protocol.

Don't get me wrong, I'm all in for making an effort to remove all user-controllable input, but now we might see shortcuts being taken to get things fixed quickly, potentially destroying a bunch of nice and niche use cases along the way.

Ars Technica · Meta and Yandex are de-anonymizing Android users’ web browsing identifiersBy Dan Goodin

I wanted to play around with #WebRTC. But then I realised my #webserver I rent at Hetzner, is just a simple one. That means no #Websockets for me, as a signaling service. So there were two options: rent something more expensive or find another way for signaling.
Guess what I chose ...
Well thankfully I quickly discovered this:
github.com/htho/php-webrtc-sig
And building on that, I've now got a simple text connection working now - after about 2,5 hours.
Also I got frustrated with chrome - I guess I just won't support that in my projects anyway, so it's fine if my #JS doesn't run there ...
