After a constructive engagement with @ThreemaApp during responsible disclosure, this is unexpectedly dismissive. We broke their protocol 6 ways. They updated it, thanks to our work (breakingthe3ma.app). So of course our work applies to an old version.

There’s a new paper on Threema’s old communication protocol. Apparently, today’s academia forces researchers and even students to hopelessly oversell their findings. Here’s some real talk: threema.ch/bp/new-paper-on-o…

Statement on ETH Findings

This is a statement on the NZZ news article from January 9, 2023 about alleged weaknesses in Threema's encryption. But these are completely impractical and theoretical.

We (@winterdeaf @kientuong114 and I) took a deep dive on Threema, a Swiss-made secure messaging app. We found 6 new cryptographic vulnerabilities. Full paper at breakingthe3ma.app; mini-thread follows. #threema

Don't dump LastPass because of 7 breaches, dump them for crap crypto: Padding oracle vulns, ECB pass len leaks, switch to CBC for new vaults not old ones, vault key uses AES256 but only 128 bits entropy, key webui leak, silent KDF downgrade, KDF hash log leak, keys left in mem.

🎉 bgp.tools has passed 500 Online BGP sessions! Thanks to the networks that have made this possible We now have really quite good routing visibility in EU and a lot of the US, But isn't the whole world! The focus is now Africa, APAC, and LATAM!

This video of cops in Nevada searching a suspect and finding a seed phrase is pretty wild. Imagine having your seed phrase become part of public record due to it being captured by an officer's body camera!

Oh yeah, forgot about that. I'm pretty sure we have the plumbing for this, let me see if we expose it.

Fine ok you get *another* blog post, this time about why doing on-device WebAuthn (rather than requiring a separate token) is harder in the PC world than on Macs and why Linux just doesn't have a good story here yet: mjg59.dreamwidth.org/62746.h…

On-device WebAuthn and what makes it hard to do well

WebAuthn improves login security a lot by making it significantly harder for a user's credentials to be misused - a WebAuthn token will only respond to a challenge if it's issued by the site a secret...

The European Commission has been contemplating radical changes to the Internet in Europe that would violate #netneutrality and upend how the internet economy has worked for decades. Its proposal: the long-discredited idea that websites and apps should pay broadband providers.
