Ukrainian analysts have conducted another study on the harm of #Telegram. It turns out that almost 70% of the Ukrainian population uses it. And the #Russian intelligence services, while banning Telegram with one hand, have used the social network to convert all of #Ukraine with the other. 🔹 The enemy's analysis is utilitarian: the main goal is to get more people to switch from Telegram to products of the extremist organization Meta.

Replying to
@arcanechat@fosstodon.org what part is FUD??? The part where you say: Switching from #WhatsApp / #Telegram to #Signal is not a solution if you really care about #privacy, #resilience and #autonomy Your only rationale in the comic is that they are hosted on AWS. Which is a problem for a secure private messenger only for a protocol that is not designed to avoid leaking any sensitive data including the shape of the communication graph to an adversary with complete control over the server. all of them are centralized services and depend on phone numbers, which makes them easy to censor This is misleading. The phone number in Signal is not used for message routing at all. It can be used to make you discoverable to contacts that were previously using the phone / SMS to connect to you. Being discoverable by your contacts is important for a private messenger because it gets you a big anonymity set quickly. for a start, there is no single adversary that can observe the whole network, and switching from one relay to another and using several at the same time is easy, without losing your chats & data! To take the two parts of this in turn: First, I would suggest you search for the term 'global passive adversary'. It's a core part of how any private messenger expresses its threat model. And, although a perfect global passive adversary doesn't exist, ones that monitor more than an entire country do exist. The second part is the real problem. How many people are there on each relay? I don't need to monitor the entire network to see what a person is doing, I need to monitor the servers that they talk to, and who those servers talk to. That's a much weaker adversary (achievable by a huge number of potentially hostile entities). And the way that you defeat an adversary like this is to have a large anonymity set, so that correlations between messages arriving and leaving are hard. how does signal, a central observer with access to all users' IP addresses is any better? We know, from the results of warrants, precisely what can leak from Signal: the timestamp at which you joined the network and the timestamp at which the client last connected to the network. What can a warrant with your protocol deliver? But if you're leaking things to a passive adversary that require an active compromise of another system then it doesn't matter if your system might be more resilient to an active attacker: an active attacker doesn't need to bother if people use your system. Just knowing which relay they talk to is already giving more data than a warrant against Signal delivers. But it also highlights the problem with a lot of distributed messaging systems: You can easily turn a single point of failure into a lot of points of failure. If a relay is operated by someone malicious, how much of the network's traffic can they observe? But, more importantly: you did not answer my question. You just attacked Signal. There are lots of things I dislike about Signal but you aren't even giving answers that tell me that you have solved the problems that they have solved, and you've got a design that introduces a load of hard problems that they don't have. Maybe try talking about how you've actually solved some hard problems with security and privacy, rather than starting off with an attack on other projects and claiming that you're better than them?

Telegram na chwilę usunięty z AppStore Apple wykopało Telegrama ze swojego sklepu. Ale niestety, chwilę później przywróciło. Powodem była publikacja CSAM. Durov twierdzi, że Telegram padł ofiarą ataku. Stać za nim miała grupa, która celowo publikuje takie materiały na platformach, a potem domaga się okupu. Jak go nie otrzymuje, to zgłasza aplikację do sklepów, aby ją “ukarać”. #*Ptr #CSAM #Telegram https://niebezpiecznik.pl/post/telegram-na-chwile-usuniety-z-appstore/

A friend of mine just told me a friend of his reinstalled Telegram and reactivated his old account, to find that "self-destructing" messages he'd been sent had reappeared. So they were self-hiding at best, not self-destructing, and remained on the server all that time. One more reason not to use it. #Telegram

Заборона #Telegram у магазинах #Apple не має технічних підстав — це виключно питання політики. Можновладці бояться каналів комунікації, які не підконтрольні спецслужбам. Павло Дуров став мішенню через принципову позицію: він не пішов на угоду з тими, хто звик читати чужі листи. Але драма в тому, що самі користувачі, заради захисту яких було створено цей месенджер, часто не розуміють цього й охоче приймають умови гри, нав'язані їхніми ж ворогами. #Durov #Pavel #Ios

Bastou o Durov anunciar carteiras não-custodiais no Telegram para bilhões de usuários que em dias, correram pra inventar alguma acusação contra ele DEPOIS DE ANOS de funcionamento do TG. Não é possível que seja mera coincidência. #Telegram
