Until now, if you lost or broke your phone, your Signal message history was *gone,* a real challenge for everyone whose most important conversations happen in Signal. So, with careful design and development, we’re rolling out opt-in secure backups. signal.org/blog/introducing-secure-backups

This battle will keep playing out over and over again until they achieve something that their own citizens have made it clear they don’t want. www.techradar.com/vpn/vpn-priv...

Well, this horrible idea refuses to die so we should refuse to let it pass and start organizing again. ec.europa.eu/commission/p...

If any Iron Maiden fans are in the Birmingham area tomorrow (the 21st), I have a couple of Premier Lounge tickets that I unfortunately can't use due to the current situation. #IronMaiden #RunForYourLivesWorldTour #IronMaiden50 @ironmaiden.bsky.social

New blog post on our (with @rikkebjerg.bsky.social and @mikaelabrough.bsky.social) USENIX'25 paper "On the Virtues of Information Security in the UK Climate Movement" where I end up reflecting on writing this, for me, unusual work. martinralbrecht.wordpress.com/2025/06/14/o...

After a long debate about whether this small typo was worth resubmitting the PDF or not, @IEEESSP 's server stopped responding one minute before the deadline and solved it for us.

All papers should publish their code. Help realize this by becoming an artifact reviewer at NDSS'26, apply here: docs.google.com/forms/d/e/1F... You'll review artifacts of accepted papers. We especially encourage junior/senior PhD students & PostDocs to help. Distinguished reviews will get awards!

uASC 2026 will take place on February 3, 2026, in Leuven, Belgium, hosted by KU Leuven. We can't wait to see you next year! Cycle 1 Paper Submission Deadline is July 15, 2025! 👉 uasc.cc #uasc26

New version of the IEEE 802.11 standard that underpins Wi-Fi was has been released. A total of 5969 pages! The number of pages clearly keeps increasing. That includes more features to defend networks, but also more features to potentially abuse 👀

Congratulations to the legendary Adi Shamir on his Levchin Prize win! Dr. Shamir donated the $10K prize money to students sponsorships.

Now we have Adi Shamir's invited talk on 'How to Securely Implement Cryptography in Deep Neural Networks' eprint.iacr.org/2025/288.pdf #realworldcrypto

In 25 years of covering national security, I’ve never seen a story like this: Senior Trump officials discussed planning for the U.S. attack on Yemen in a Signal group--and inadvertently added the editor-in-chief of The Atlantic. www.theatlantic.com/politics/arc...

It’s finally out - our 107-page analysis of key exchange in Telegram in which we proved (after massive effort) that the bespoke protocol is ok, if you’re willing to make some uncomfy assumptions on the home-grown KDF. With @malb.bsky.social, @eyalr0.bsky.social, Lenka Mareková and Igors Stepanovs.

The tentative program for Real World Crypto 2025 is live! rwc.iacr.org/2025/program... A huge thanks to my co-chair @malb.bsky.social and all the amazing program committee members for helping put this together. I'm looking forward to seeing everyone in Sofia! #realworldcrypto

Because of new tariffs, submissions to crypto with a non US author have a 20% reduction to their page limit.

The list of accepted talk at @rwc.iacr.org is now available: rwc.iacr.org/2025/accepte... Early registration ends 26 February. CC: programme co-chair @nicksullivan.org

After an embargo of 8 months, we are glad to finally share our USENIX Security '25 paper! We found more than 4 MILLION vulnerable tunneling servers by scanning the Internet. These vulnerable servers can be abused as proxies to launch DDoS attacks and possibly to access internal networks.

Excited to announce a funded PhD position analysing the Social Foundations of Cryptography here at King's College London with me and @malb.bsky.social . Applications open now, feel free to reach out for a chat. social-foundations-of-cryptography.gitlab.io Link in next post!

CFP for uASC 25 is still open. We have rolling reviews, and 1 submission is already accepted. If you have interesting results on microarchitecture security (incl. weak threat models or reproducing prior work), check out the CFP at uasc.cc The CFP closes **Jan 28**
