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.

@signalapp no it's not.
Being a #centralized, #SingleVendor & #SingleProvider solution subject to #CloudAct makes you inherently vulnerable by your own choice and thus trivial to shutdown compared to real #E2EE with #SelfCustody of all the keys and true #decentralization as well as #SelfHosting (i.e. #PGP/MIME [see @delta / #deltaChat et. al.] and #XMPP+#OMEMO [see @monocles / #monoclesChat et. al.]!)
And don't even get me started on you collecting #PII (espechally #PhoneNumbers) for no valid reason, (thus violating #GDPR & #BDSG)...
But yeah, I'll be patient to shout "#ToldYaSo" to your annoying cult of fanboys!
"Nutzt Signal!"
Außer, wenn man kein Google Android/Apple iOS hat/haben will.
Außer, wenn man nicht Amazon AWS nutzen/finanzieren will oder befürchtet, DJT könnte jederzeit den Zugang sperren.
Außer, wenn man seine Telefonnummer nicht als Chat-Id verwenden will.
Email vs. Signal ist eine falsche Dichotomie. Es gibt freie, föderierte Alternativen mit Clients für die meisten Betriebssysteme und ohne Telefonnummernzwang.
It’s time for real interoperability. Let’s make it happen.
The #DMA targets walled gardens and messaging interoperability. Meta, the designated gatekeeper, offers an solution that falls short of its goals.
The XMPP Standards Foundation (@xmpp) publishes an Open Letter to Meta, to advocate for adoption of #XMPP for messaging interoperability.

@janet_catcus #XMPP+#PGP may be a good option if you don't want to deal with half a dozen #OMEMO keys...
@Andromxda @mollyim no it's not bs and fanboying @signalapp isn't going to change that.
If #Signal was secure it would be the #1 comms tool of organized crime...
Real professionals use #SelfHosting capable, fully #FLOSS'd solutions like #PGP/MIME & #XMPP+#OMEMO.
It's just me reading the room: Cuz #ComSec isn't done woth "JuSt UsE sIgNaL!" and everyone who claims so without pointing out #OpSec, #InfoSec & #ITsec is BSing hard.
Fortunatelty, @thunderbird and @tails_live / @tails / #Tails and many other tools make that easier than ever before.
@crazy_pony when @signalapp isn't being run as a #VCMoneyBurningParty and they take #InfoSec, #OpSec, #ComSec & #ITsec serious and stop shilling the #Shitcoin #Scams that is #MobileCoin!
For everyone else, there's #XMPP+#OMEMO (see @monocles / #monoclesChat) & #PGO/MIME (see @delta / #deltaChat)…
@walkinglampshade @jrredho @fj It's basic #InfoSec, really:
Thus #Signal fails at protevting #Journalists and theor sources because they do have that data and can be #subopena'd for it if they don't already provide #BulkSurveillance & #LawfulInterception #API|s to comply with #CloudAct. (Or are you guys so naive and believe @Mer__edith will risk dying of old age in jail for non-paying users?)
And if you believe "this won't ne used/abused me because I'm from 'Murica!" and point at #ANØM as an example, then you really ignored all tze #Cyberfacism since 9/11…
@froge @fj I'm not replacing @signalapp with "random tools" but good options.
Like @delta & @thunderbird as well as @monocles / #monoclesChat & @gajim which work flawlessly over @torproject / #Tor using @tails / @tails_live / #Tails and @guardianproject / #Orbot respectably.
Considering the costs of even acquiring and upkeeping an #anonymous #SIM, I'd rather pay €2 p.m. for #XMPP+#OMEMO and #PGP/MIME-supported #eMail with the option of self-custody than $2,50+ p.m. just to keep a phone number.
Or is anyone here expecting @Mer__edith to risk jail for life amd not comply with #CloudAct?
It stenches like #ANØM, because NOTHING IS FOR FREE and running a #VCmoneyBurningParty is expensive...
I just delved into XMPP & OMEMO, despite limited experience. This old but intriguing article caught my attention: https://soatok.blog/2024/08/04/against-xmppomemo/ Worth a read?
#XMPP #OMEMO #PrivacyMatters
@fj I still think @signalapp has fundamental flaws like demanding #PII (#PhoneNumbers can't be obtained anonymously around the globe and are trivial to track down to devices and thus users), being subject to #CloudAct as an unnecessary & 100% avoidable risk as well as #Shitcoin-#Scam shilling (#MobileCoin) and it's #proprietary, #SingleVendor & #SingleProvider nature that makes it inferior to real #E2EE with #SelfCustody like #PGP/MIME & #XMPP+#OMEMO!
Reminder to people who work in the #military, #healthSector or any other institution with #clearance levels:
Please use #InstantMessaging systems, that reflect them, for #classified information.
E.g. there is "XEP-0258: #Security Labels in #XMPP" https://xmpp.org/extensions/xep-0258.html
@700Sachen @Bingenberger @groso dann doch lieber auf #XMPP+#OMEMO über #Tor migrieren, weil da funzen Sprachnachrichten nicht statt #NSAbook mit extea #Stimmdaten zu füttern.die dank #CloudAct US-Regierungseigentum werden und/oder dann für #Deepfakes genutzt werden können.
