Telegram has been blocked temporarily or permanently by some governments including Iran, China, Brazil, and Pakistan. Regarding Telegram, the report cites its lack of end-to-end encryption by default, its Russian origins and third-party open source intelligence as major critical points. In September 2021, a Russian researcher published details about a bug with the self-destruct feature that allowed the user to recover deleted photos from their own device. All issues were patched before the paper’s publication with a security bounty paid out to the researchers. In July 2021, researchers from Royal Holloway, University of London and ETH Zurich published an analysis of the MTProto protocol, concluding that the protocol could provide a “confidential and integrity-protected channel” for communication. The attack relied on people downloading a malware-infected file from any source, at which point it would replace Telegram files on the device and ‘clone’ session data.

In a later blog post, Durov directly stated that the block was a result of pressure from Google and Apple as refusal to comply with their policies would result “in an immediate shutdown of Telegram for millions of users”. The messages were considered vulgar, racist, and homophobic, with members of the chat discussing how they would use the media to target potential political opponents. In July 2024, ESET reported a vulnerability allowed malicious files being sent to users masked in multimedia. It took 11 days for the database to be taken down, but the researchers say the data was accessed by other parties, including a hacker who reported the information to a specialized forum. On 30 March 2020, an Elasticsearch database holding 42 million records containing user IDs and phone numbers of Iranian users was exposed online without a password.

The Telegram team responded that the flaw does not affect message security and that “a future patch would address the concern”. Nevertheless, they said they saw “no reason why Telegram should use a less secure encryption scheme when more secure (and at least as efficient) solutions exist”. In December 2015, two researchers from Aarhus University published a report in which they demonstrated that MTProto 1.0 did not achieve indistinguishability under chosen-ciphertext attack (IND-CCA) or authenticated encryption. The EFF said that the results “should not be read as endorsements of individual tools or guarantees of their security”, and that they were merely indications that the projects were “on the right track”.

App support

• Pavel sold his remaining stake in VK and left Russia after resisting government pressure.
• Users with a Telegram Premium subscription have a number of “boosts” that they can give to channels, which allow the channel to “level up” and unlock features, such as the ability to customize messages or post stories as the channel.
• So, it really boils down to what you value most in a messaging app.
• As of July 2024, Telegram’s headquarters and development team are based in Dubai.
• They can respond to messages or mentions directly or can be invited into groups, and are able to perform tasks, integrate with other programs and host mini apps.
• The table outlines each payment method, typical minimum amounts, and how fast your funds will appear in your casino account.
• A Student Information System (SIS) is a centralized software platform that manages all student-related data and academic processes throughout a student’s lifecycle at a higher education institution.

After learning about Telegram and reading about encryption, you might be wondering if default encryption really matters. Even if you are just curious about how Telegram works, these tools turn it into more than just a place to chat. If you are a developer, Telegram API for apps allows you to tap into Telegram’s robust infrastructure to build your own applications. Imagine being able to program Telegram to perform tasks beyond just sending messages, such as answering inquiries, setting reminders, or even engaging in gameplay. Your priorities will guide which app is the best fit for you. WhatsApp keeps things simple with minimal customization and end-to-end encryption as the standard, focusing on secure, straightforward communication.

Secret Chats use End-to-End Encryption to ensure that a message can only be read by its intended recipient.We keep expanding the boundaries of what you can do with a messaging app. SiS is the campus database used to manage student academic data for admissions, registration, enrollment, billing and financial aid. NOVA’s Student Information System (SIS) is your central source for accessing all your essential student information. Additional features are in development to improve the student experience. Transitioning to a new SIS can present unique hurdles, like data migration and user adoption. By merging student information management with essential financial and HR functions, we can bridge the gaps between data and departments.

In January and February 2018, the company ran a private sale of futures contracts for Grams, raising around $1.7 billion. In late 2020, Durov announced that Telegram will consider adding paid features aimed at enterprise clients. Durov said the bond sale “will further solidify our position as an independent platform that is able to challenge the ‘Goliaths’ of our industry”. According to press reports, prior to the bonds placement, Durov had rejected an investment offer for a 5–10% stake in the company as well as several undisclosed ones, valuing the company in a $30–40 billion range. A day later, the Mubadala Investment Company stated that Russia’s sovereign wealth fund participated in its deal undisclosed through the Russia-UAE joint investment platform to buy convertible bonds. The funding was required to cover the debts amounting to $625.7 million, including $433 million to investors who bought futures for Gram tokens in 2018 and included purchasers such as David Yakobashvili.

In 2017, in an attempt to monetize Telegram without advertising, the company began the development of a blockchain platform dubbed either “The Open Network” or “Telegram Open Network” (TON) and its native cryptocurrency “Gram”. In December 2024, Telegram CEO Pavel Durov announced that Telegram had reached profitability, due to significant growth in Premium subscriptions and Telegram ad sales, assisted by the other monetization features launched throughout 2024. In June 2024, Telegram launched Telegram Stars to facilitate in-app purchases of digital goods and services, in compliance with policies from the App Store and Play Store. In addition, Telegram offers functions for making payments directly within the platform, alongside an external service such as Stripe.
Telegram has various client apps, some developed by Telegram Messenger LLP and some by the community. Telegram Messenger LLP has servers in a number of countries throughout the world to improve the response time of their service. As with most instant messaging protocols, apart from XMPP, Telegram uses centralized servers. However, the service was criticised for being vulnerable to online brute-force attacks. In July 2018, Telegram introduced their online authorization and identity-management system, Telegram Passport, for platforms that require real-life identification. For example, an article titled “Telegraph (blog platform)” published on betzino casino 17 November would receive the URL /Telegraph-blog-platform-11-17.

• This means we may receive a commission if you click through and take action—such as signing up for a service or making a purchase.
• Users can freely join public chats and find them using the in-app search function, while private chats require an invitation.
• In late 2020, Durov announced that the company was working on its own ad platform, and would integrate non-targeted ads in public one-to-many channels, that already were selling and displaying ads in the form of regular messages.
• He focuses on producing content that is both accurate and accessible for diverse audiences.
• Telegram’s CEO then said that the requested data was technologically impossible to obtain.
• Nikolai created the MTProto protocol that is the basis for the messenger, while Pavel provided financial support and infrastructure through his Digital Fortress fund.

They criticized how, unless modified first, the default general security model stores all contacts, messages and media together with their decryption keys on its servers continuously; and that it does not enable end-to-end encryption for messages by default. Telegram’s internal reporting system has an option to report content that contains child abuse, including specific messages in groups and channels. Durov planned to power TON with the existing Telegram user base, and turn it into the largest blockchain and a platform for apps and services akin to a decentralized WeChat, Google Play, and App Store.
The company only partially fulfilled a court request for personal data on two antisemitic Telegram groups, which authorities considered an intentional lack of cooperation. Throughout 2020, the Islamic Revolutionary Guard Corps used groups and channels to dox Iraqi and Iranian citizens, while sharing propagandistic posts on the platform. In 2023, Saudi Arabia’s Global Center for Combating Extremist Ideology (Etidal) reported that in collaboration with Telegram, over 59 million pieces of extremist content had been removed from the platform since 2022. In September 2024, Telegram announced that it would begin to hand over users’ IP addresses and phone numbers to authorities who have search warrants or other valid legal requests. Such content is usually linked to Telegram allowing misinformation on the platform as, according to Pavel Durov, “conspiracy theories only strengthen each time their content is removed by moderators”.
In September 2021, Telegram added interactive emoji, a type of animated emoji which also play a fullscreen effect in the chat. When typing in an emoji, the user is offered to send the respective sticker instead. Stickers are cloud-based, high-resolution images intended to provide more expressive emoji.
Telegram then gained over 70 million new users as a result of an outage which affected Facebook and its affiliates on 5 October 2021. On 8 January 2021, Pavel announced in a blog post that Telegram had reached “about 500 million” monthly active users. On 24 April 2020, Telegram announced that it had reached 400 million monthly active users. According to the US Securities and Exchange Commission, as of October 2019, Telegram had 300 million monthly active users worldwide. By March 2018, that number had doubled, with Telegram reaching 200 million monthly active users.
It received points for having communications encrypted in transit, having its code open to independent review, having the security design properly documented, and having completed a recent independent security audit. Telegram’s default chat function received a score of 4 out of 7 points on the scorecard. It noted that while the message data is encrypted on the device, it could not analyze the transmission due to a lack of source code. Telegram has defended the lack of ubiquitous end-to-end encryption by saying that online-backups that do not use client-side encryption are “the most secure solution currently possible”.
