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.

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.

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!

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…

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.
