There are no known security issues with "Siacs OMEMO" / OMEMO v0.3¹ despite of what some very loud Signal fans would like you to believe. It has been audited by a third party² who took a longer look at it than all of the Signal fans combined.
Yes, #OMEMO v0.7+ (or TWOMEMO 😜) is a cleaner spec with more features (most notably Stanza Content Encryption). That’s why we wrote it. I’m a co-author. That doesn’t mean v0.3 is insecure.

@ireneista @contrapunctus @grimalkina @Lunaphied Clicking on the ellipsis at the bottom right of Daniel's post and selecting 'Expand this post' show other replies, but the one from @winfriedtilanus is the most useful.
@adamhotep @snopes rather than using Signal, I suggest self hosting an #XMPP server with accounts for key people. Create a group for sharing MFA keys and keep this sensitive information under your control. If your xmpp server was, say chat.snopes.com, then you can leverage DNS security to have confidential discussions with external people too.

@ireneista @contrapunctus @grimalkina @Lunaphied There is an interesting thread here on Federated Metadata privacy
@thevril @contrapunctus @snikket_im @grimalkina I do like that list too, and use Conversations (via #fdroid and donate via @mastadon.xyz@liberapay). My aim is to inform people that alternatives to monolithic Instant Messengers exist, and encourage more mainstream use.
“The fundamental weakness of Western civilization is empathy, the empathy exploit,” Musk said. “There it’s they’re exploiting a bug in Western civilization, which is the empathy response.”
-Elon Musk, March 6, 2025
“In my work with the defendants (at the Nuremberg Trials 1945-1949) I was searching for the nature of evil and I now think I have come close to defining it. A lack of empathy. It’s the one characteristic that connects all the defendants, a genuine incapacity to feel with their fellow men. Evil, I think, is the absence of empathy.”
-Captain G. M. Gilbert, the Army psychologist assigned to watching the defendants at the Nuremberg trials

@ireneista @contrapunctus @grimalkina @Lunaphied I am concerned about the risks associated with metadata for some time, specifically in the context of Who pays for WhatsApp, but any centralised system, e.g. Signal, or Telegram - even if well intentioned, will be vulnerable to insiders being bribed of coerced. Federation limits the insider information scope.
@bun @GossiTheDog Bring Your Own Device. An acknowledgement by businesses that many people have, for example a personal mobile phone which is more recent than the one they issue, and that it is very inconvenient to operate with two devices. They benefit from the intermingling of work and personal life, with people taking work home, for example, but this introduces complex security issues.
@liv Mythic-Beasts do DNS registration, are technical and customer focussed, and, unlike many companies, understand the fediverse by being here @beasts
The legality (not wisdom) of putting European private data on US clouds hinges on the availability of the US Privacy and Civil Liberties Oversight Board. Trump neutered this board, and the European parliament has taken notice & asked the European Commission what they think:
