🔐 Discord introduces end-to-end encryption with Messaging Layer Security (MLS) 🔐 Im really happy to see another large scale MLS deployment. It shows the technology is fit for purpose, demonstrably so. discord.com/blog/meet-dave…
Today I learned about pax.dev and I was briefly hopeful that we might be able to replace Flutter with something rustier. But no, Flutter remains the most comprehensive UI framework besides the native options. I wonder when we’ll have a Rust UI framework that good.
📣 New release of OpenMLS 📣
We are happy to announce the release of OpenMLS v0.6, a significant update to our open-source MLS implementation. This version includes several new features and improvements. Read all details on the blog: blog.openmls.tech/posts/2024-09-…
We are hiring two Rust engineers!
We #hiring a full-time and a freelance Senior Rust Engineer to help us build the next generation of private & secure messaging. If you’re interested in joining our team, please apply today! For friends of secure messaging 🥷, please share our post. join.com/companies/phoe…
Will 2024 be the year the public realizes Telegram is not a private & encrypted messenger?
I propose an alternative slogan for @FastlaneTools: "Just one more lane. That'll fix it."
In 2024, what are good European cloud providers? They must offer managed databases (postgres, redis) and possibly managed kubernetes.
I think the kitchen appliances from @SharkNinja are great, but the French translation of their recipes are really next level. I secretly hope they are handcrafted and a testament to how Americans view the French.
Great and nuanced thread about secure messaging:
Some folks are discussing what it means to be a “secure encrypted messaging app.” I think a lot of this discussion is shallow and in bad faith, but let’s talk about it a bit. Here’s a thread. 1/
Privacy leak in @wire: Sending read receipts is switched off on my end but I can still see read receipts from other people.
This is possibly the biggest downside of the Signal protocol. It is not new and it’s been an accepted risk since the beginning. With MLS we have a way to significantly improve the situation: the server can make sure everyone receives the same message without impacting privacy.
1/ An integrity issue with #WhatsApp and Signal Protocol 🧵 medium.com/@TalBeerySec/h… Users expect their chats’ history to be the same across all devices. However, we show that a rogue client can send different messages to the same user’s different devices
We attended the Real World Crypto Symposium in Toronto where @raphaelrobert talked about how far MLS has come since RWC 2019. Highlights: - Post-quantum resistance and how easy it is to upgrade from current schemes - Deployment in existing products like Webex and Discord (🧵1/2)
WhatsApp shared first details on how they will comply with the DMA. We are critical of the Signal protocol, as there has never been a complete specification that allows secure implementation of the protocol. This was one of the main reasons to develop MLS. netzpolitik.org/2024/interoper…
This is one of the reasons we are working on the virtual client extension for MLS: hiding how many devices users have and which one does a key rotation
So the overall point here, that E2E services leak a ton of metadata through key updates, is a good one. Same thing goes for Apple: you can more or less enumerate all devices if you reverse the Apple Directory Service APIs.
We ended 2023 with a talk at #37C3. @raphaelrobert and Konrad presented Messaging Layer Security (MLS). The room was packed and some people couldn't attend – luckily the talk is now online. 🍿 media.ccc.de/v/37c3-12064-r… #securemessaging #encryption #e2ee #messaginglayersecurity
📣 Today at #37c3, 3:45pm, Konrad and I will give a talk in hall Zuse about Messaging Layer Security (MLS). They call it RFC 9420, we say MLS: A new IETF standard for end-to-end encryption, bringing improvements in performance and security. 👉 fahrplan.events.ccc.de/congress/2023/…
We are very excited to be at #37c3 in Hamburg after a long pandemic break. On day 3 (29.12., 3:45pm), @raphaelrobert and Konrad will give a talk on “RFC 9420 – or how to scale end-to-end encryption with Messaging Layer Security (MLS)” 👉 fahrplan.events.ccc.de/congress/2023/…
Check out our blog post where we examine the push notification problem and address misconceptions! In the wake of recent reports on #surveillance via push notifications, many people have been confused how it affects their #privacy when using messengers. blog.phnx.im/privacy-of-pus…
