@kuketzblog da widerspreche ich vehement.

Es gibt #proprietär|e #Silos welche qua #SingleVendor & #SingleProvider-Aufbau als #InformationBlackhole agieren (u.a. #WhatsApp, #Signal, #Threema, #Session, #Telegram, #discord, …)

und es gibt #OffeneStandards die #Wahlfreiheit zwischen #Clients, #Plattformen, #Servern und #Providern ermöglichen (u.a. #IRC, #Zulip, #RocketChat, ...) und echte #E2EE mit #SelfCustody aller Schlüssel ermöglichen (u.a. #XMPP+#OMEMO & #PGP/MIME)...

Natürlich steht es Menschen frei irgendeinen großen, zentralisierten Anbieter zu nutzen, nur wird dieser am ehesten zur #Enshittification neigen und mit #PII wie #Telefonnummern entsprechende Begierlichkeiten wecken!

@my_millennium @dbrgn @monocles @gajim Ist trotzdem #zentralisiert (#SingleVendor & #SingleProvider) und damit #proprietär und untauglich, weil gegen #KeckhoffsPrinzip und grundlegende #InfoSec & #ComSec verstoßend!

@stormii @debby okay.

Still a #centralized, #SingleVendor & #SingleProvider service that snitches on users if it ain't yet another #Honeypot like #ANØM...

@debby #Mumble, #IRC, #XMPP (+OMEMO = @gajim / #monoclesChat) & #Linphone (#SIP / #VoIP) are the better options. #NextcloudTalk also exist and @monocles as well as @Stuxhost offer that.

OfC #JitsiMeet and #WebCall are also great!

@adisonverlice I think that's dangerous disinfo as @torproject actively works against attempts to fingerprint and track #Tor users.

  • I do consider Tor more private than any #VPN simply becaise they can neither ban users nor identify them.

In fact, Tor has been designed with the explicit goal to circumvent #Firewalls and #InternetCensorship methods like #DeepApcketInspection.

As a matter of principle I'd never vouch for any #centralized, #SingleVendor and/or #SingleProvider solution of any kind, including #Session.

  • Tor is sufficiently decentralized in that it is not only completely #OpenSource but has proven to not have SPOFs in the form of maintainers and is able to yeet proplematic folks (unlike #WikiLeaks!)…

@adisonverlice it's not just re: #Governments (tho #Project2025 explicitly endorses unsactioned comms to twart attempts at #FIOA or any #accountability for that matter), but individuals or any organization:

And if #EncroChat got pwned, who's gonna guarantee @signalapp won't if it's actually secure or isn't an #InsideJob like #ANØM.

After all, both #Signal's Organization and key people like @Mer__edith are known to the authorities by more than just their legal name.

  • What's gonna prevent #Trump from doing a "bag&drag" on her or getting his goons to put a gun on,the developers' heads and force them to,#d0x all users and #backdoor everything (if they didn't already got forced to have some "#LafwulInterception" gear in a closet like #Room641A...

After all, Signal can't pull the 5th and refuse to comply!

@bob_zim yeah. Seen it. in the writeup by @micahflee ...

I just hope to find any that ain't #NetLock'd / #SimLock'd to #Verizon and that these support more than #US-#LTE bands...

  • Not shure if it needs a valid #SIM or just an #ICCID + #Ki on a #SIM to get going (cuz in #Germany it's hard [imported #SIM] to illegal [domestic SIMs] to get an anonymous SIM since 07/2017.

I just wish @eff wouldn't expect everyone to use #centralized, #SingleVendor & #SingleProvider services like @signalapp in the age of #CloudAct, cuz neither I nor anyone I'd trust would submit #PII to them like a #PhoneNumer as a matter of principle!

@menel @patrick and #Signal despite their #FUD and #MarketingLies is a very #cebtralized, #SingleVendor & #SingleProvieer system relying on #GAFAMs and their #API|s as well as neither allowing #SelfCustody nor #SelfHosting.

  • Given the risks if being bound to #US law (incl. #CloudAct) it's just not an option.

Not to mention it's toxic followers that avt like cultists!

Kevin Karhan :verified:kkarhan@infosec.space

@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!

@dzwiedziu @fj @signalapp not really, as the #Metadata #FUD cited by #Signal is mitigateable with proper measures.

  • You can't even run Signal over @torproject and even if that point is moot when you're forced to quasi-#KYC by virtue of a #PhoneNumber aka. #PII they have neither legitimate interest nor technical reason to demand in the first place!

Every claim that things like #ITsec, #InfoSec, #OpSec & #ComSec can be solved with "Just use Signal!" is "#TechPopulism" at best if not being a "#UsefulIdiot"!

@signalapp It's not #disinfo when one points out that you demand #PII aka. #PhoneNumbers from Users and that is literally a architectural vulnerability, alongside your #proprietary & #Centralized #Infrastructure.

Not to mention the lack of @torproject / #Tor support with an #OnionService or the willingness to fulfill #cyberfacist "Embargoes" or shilling a #Shitcoin #Scam named #MobileCoin!

  • #KYC is the illicit activity!!!

And don't get me started on the #cyberfacism that is #CloudAct.

  • If you were secure, criminals would've used your platform so hard, it would've been shutdown like #EncroChat and #SkyECC.

I may nit have allvthe.evidence yet, but #Signal stenches like #ANØM: #Honeypot-esque!

@signalapp I disagree because your platform is #proprietary, #SingleVendor, #SingleProvider and doesn't allow for #SelfHosting, #SelfCustody of all the Keys and you demand #PII in the form of a #PhoneNumber which can be used.to track users down!

@ueeu I think crucial parts is looking at it's components, dependencies, size and for apps permissions.

#ReproduceableBuilds for example are important, so the actually released source code is what people actually get served as basis.

Plus in terms of #security, choose *real #E2EE with #SelfCustody of all the #Keys!

@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!

@licho @osman provide evidence the code @signalapp released is actually being deployed.

Not to mention pushing a #Shitcoin-#Scam (#MobileCoin) disqualifies #Signal per very design!
youtube.com/watch?v=tJoO2uWrX1M

  • Given the collection of #PII like #PhoneNumbers, the ability to restrict functionality based off those and the fact that #Signal is subject to #CloudAct make it inherently not trustworthy.

And don't even get me started on the fact.it's not sustainable to run it as a #VCmoneyBurningParty!

Same as identifying users: They already got a #PhoneNumber which in many juristictions one can't even obtain without #ID legally, thus making it super easy to i.e. find and locate a user. Even tze cheapest LEAs can force their local M(V)NOs to #SS7 a specific number...

  • All these are unnecessary risks, that could've been avoided, but explicitly don't even get remediated retroactively!

Again: Signal has a #Honeypot stench, and you better learn proper #E2EE, #SelfCustody and #TechLiteracy because corporations can't pull the 5th [Amendment] on your behalf!

@osman, no because @signalapp is a #proprietary, #centealized, #SingleVendor & #SingleProvider solution that demands #PII like #PhoneNumbers for no valid reason, is subject to #CloudAct and only continues to exist because it's convenient as a means to fo #BulkSurveillance and mark it's users as #PeopleOfInterest.

@encthenet granted, I'd be wary given the fact that @signalapp is a #proprietary, #centralized, #SingleVendor & #SingleProvider solution.

@Catwoman69y2k @dragonfriend most importantly:

Only with #SelfCustody of all the keys, #SelfHosting of the entire infrastructure and everything being #OpenSource, one can assure (and [let it be] audit[ed] independently) that the #advertised #promises are in fact true.

Cuz not expecting @Mer__edith to break is the same level of "#TrustMeBro!" assurances as #ANØM, #EncroChat, #SkyECC, #WhatsApp etc. do in their #advetising #lies!

  • Remember: Corporations/Foundations/non-profits/... don't have a right to be silent , only individuals, and even then there are certain juristictions that have #KeyEscrow laws (i.e. #France, #Russia, #KSA, #China, #India, #UK , ...) in the books!

@ckrypto if@signalapp@mastodon.world wasn't complying with #CloudAct, @Mer__edith would be in jail.

Not to mention even if Signal keeps their "#OpenSource" code updated - which is doubtful, NOONE can actually #verify that it's the code you actually use - regardless if #backend / #Server or #client / #App!

  • #Signal is as secure as #ANØM, otherwise it would've been shutdown ages ago.

Also if Signal was designed for #security, it would've been #decentralized as #XMPP+#OMEMO and not demand #PII like #PhoneNumbers which oftentimes cannot be obtained anonymously in many juristictions at all!

By comparison, @delta doesn't require any PII, only an #eMail account, and @monocles isn't a #VCmoneyBurningParty but sustainable due to #subscription and they don't even require any personal details for #payment: #CashByMail and #Monero are accepted.

Again: It's Signal alone who have to evidence they are trustworthy, and all I get are "#TrustMeBro!" replies, which means they are not to be trusted.

  • Not to mention, it's just not sustainable to run a #service without #revenue, even if it's run entirely by unpaid volunteers and gets all it's #hosting and #costs donated, someone has to pay for expenses due to #abuse of a service (which is an inevitability come mass adoption)...

Whereas with #XMPP I can completely setup my own server and client, even build my own if I don't trust anyone else and pay someone to audit the code.

Whereas with XMPP & PGP/MIME #eMail I can layer @torproject / #Tor over it, make it an #OnionService and keep that thing under my bed with a literal killswitch...
