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…

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.

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.

I blogged about using #ACME to automatically, securely, and reliably protect all your workload connections with #mTLS and achieve authenticated End to End Encryption #E2EE: blog.daknob.net/workload-mtl…

I blogged about how I’m using #ACME to issue #mTLS and #SSH certificates for my personal infrastructure: blog.daknob.net/acme-end-use… My end goal is to make sure the devices I’m using don’t have access to my stuff for most of the time. I also move to 100% hardware-backed keys!
