We are grateful for all the suggested fixes to TVM and FunC. Most of those have been implemented, and the TON TestNet has been restarted today.

We will announce Stage 2 of the blockchain competition in the next few weeks. Please note that the TON security bug bounty program is extended – we will be accepting and rewarding security bug reports even though this stage of the contest has ended.

🆕 Trasferimento a testnet2

Sul sito ufficiale test.ton.org sono state pubblicate informazioni sugli aggiornamenti della rete di test:
ecco le novità:
• IMPORTANTE: Si noti che la rete di test è stata rilanciata il 15.11.2019. Per connettersi alla nuova rete di test ("testnet2"), è necessario ricompilare il software da fonti aggiornate e scaricare il file di configurazione aggiornato da questo sito. Tutti gli account creati in precedenza e i contratti intelligenti non esistono più.
• 15.11.2019: la dimensione massima del trasferimento ext_message è stata aumentata a 16 KiB, quindi ora i contratti intelligenti più grandi possono essere distribuiti da qualsiasi nodo completo (aggiornato).
• 15.11.2019:Il tasso minimo di convalida è stato ridotto a 10.001 GRAM di prova.

⚡️ API: Autorizzazione utente
Nella pagina ufficiale https://core.telegram.org/api/auth sono apparse indicazioni sul come registrare il telefono di un utente per iniziare a utilizzare l'API per emulare un'applicazione di un utente associato ad un particolare DC.
In pratica, per risolvere errori di flood dovuti a troppi tentativi di accesso durante i test, sono presenti dei prefissi di numeri di telefono riservati per verificare la correttezza dei reindirizzamenti di gestione dell'applicazione tra DCs, iscrizioni, accessi e flussi 2FA. Questi numeri sono disponibili solo su DCs di test...

The results of the themes contest have finally arrived. We carefully inspected each of the 341 themes submitted by the 277 designers and selected the ones we considered best. While none of the themes submitted are perfect, here’s how we identified the winners:

1. Themes that supported more than 2 platforms were slightly prioritized.
2. Themes that could be built within a few minutes using the Telegram UI were discarded.
3. Themes that we deemed unusable (e.g. those with low contrast / dissonant color palettes) were likewise discarded.

Thank you for taking part in this competitive process. We hope you had fun!

The Telegram Data Clustering Contest starts now.

Based on the input data we provide, you are expected to develop an algorithm that:

1. Identifies content in English and Russian and discards the rest.
2. Identifies news articles from the result of (1) and discards the rest.
3. Classifies each news piece from the result of (2) into one of these 7 categories: Society, Economy, Technology, Entertainment, Science, Sports and Other.
4. Identifies news pieces about the same event and groups them together into news threads.
5. Sorts news threads based on perceived importance.

Below is the sample input data. We will be publishing more sample data sets as the contest progresses. Check out the detailed denoscription of the contest task here (and here in Russian).

Participants have two weeks until December, 2 (the deadline is 23:50 Dubai time) to come up with a solution and upload it to @jobs_bot.

The authors of the best solution will share a prize fund of $100,000 and will be able to take part in the second stage of the contest, getting a chance to claim another $100,000 in prizes.

🔥Che cosa succede quando uno stato decide di chiudere internet?

Stando ai dati offerti da TGStat.com, in seguito alla scelta di chiudere internet da parte del Consiglio Supremo della sicurezza nazionale dell'Iran, il numero totale delle visualizzazioni all'interno dei dei canali Telegram iraniani è diminuito di quasi 9 volte: passando da 1.3 miliardi visualizzazioni al giorno a 150 milioni al giorno.

È calato anche il numero totale di pubblicazioni in questi giorni "senza Internet". Si è passati da 350 mila pubblicazioni al giorno a sole 75 mila pubblicazioni.

In May, I predicted that backdoors in WhatsApp would keep getting discovered, and one serious security issue would follow another, as it did in the past [1]. This week a new backdoor was quietly found in WhatsApp [2]. Just like the previous WhatsApp backdoor and the one before it, this new backdoor made all data on your phone vulnerable to hackers and government agencies. All a hacker had to do was send you a video – and all your data was at the attacker’s mercy [3].

WhatsApp doesn’t only fail to protect your WhatsApp messages – this app is being consistently used as a Trojan horse to spy on your non-WhatsApp photos and messages. Why would they do it? Facebook has been part of surveillance programs long before it acquired WhatsApp [4][5]. It is naive to think the company would change its policies after the acquisition, which has been made even more obvious by the WhatsApp founder’s admission regarding the sale of WhatsApp to Facebook: “I sold my users’ privacy” [6].

Following the discovery of this week’s backdoor, Facebook tried to confuse the public by claiming they had no evidence that the backdoor had been exploited by hackers [7]. Of course, they have no such evidence – in order to obtain it, they would need to be able to analyze videos shared by WhatsApp users, and WhatsApp doesn’t permanently store video files on its servers (instead, it sends unencrypted messages and media of the vast majority of their users straight to Google’s and Apple’s servers [8]). So – nothing to analyze – “no evidence”. Convenient.

But rest assured, a security vulnerability of this magnitude is bound to have been exploited – just like the previous WhatsApp backdoor had been used against human rights activists and journalists naive enough to be WhatsApp users [9][10]. It was reported in September that the data obtained as a result of the exploitation of such WhatsApp backdoors will now be shared with other countries by US agencies [11][12].

Despite of this ever-increasing evidence of WhatsApp being a honeypot for people that still trust Facebook in 2019, it might also be the case that WhatsApp just accidentally implements critical security vulnerabilities across all their apps every few months. I doubt that – Telegram, a similar app in its complexity, hasn’t had any issues of WhatsApp-level severity in the six years since its launch. It’s very unlikely that anyone can accidentally commit major security errors, conveniently suitable for surveillance, on a regular basis.

Regardless of the underlying intentions of WhatsApp’s parent company, the advice for their end-users is the same: unless you are cool with all your photos and messages becoming public one day, you should delete WhatsApp from your phone.

[1] – Why WhatsApp will never be secure

[2] – WhatsApp users urged to update app immediately over spying fears

[3] – WhatsApp Android and iOS users are now at risk from malicious video files

[4] – Everything you need to know about PRISM

[5] – NSA taps data from 9 major Net firms

[6] – WhatsApp co-founder Brian Acton: 'I sold my users' privacy'

[7] – Hackers can use a WhatsApp flaw in the way it handles video to take control of your phone

[8] – WhatsApp is storing unencrypted backup data on Google Drive

[9] – WhatsApp hack led to targeting of 100 journalists and dissidents

[10] – Exclusive: Government officials around the globe targeted for hacking through WhatsApp - sources

[11] – Police can access suspects’ Facebook and WhatsApp messages in deal with US

[12] – Facebook, WhatsApp Will Have to Share Messages With U.K.

Telegram keeps growing at a rate of ~50% annually in DAU. This extraordinary growth, unfortunately, still comes with certain growing pains.

Yesterday from 1PM to 2PM GMT about 15% of users who were online at that time experienced connection issues on Telegram. This disruption mainly affected users from Germany, Iraq, Uzbekistan, Russia, Ukraine, Kazakhstan and Belarus.

We apologize for each of the messages we failed to deliver during that hour. We are striving to make our platform as reliable as possible. We are proud that, even despite some attempts to disrupt its availability (like the DDoS from China in June), every year Telegram becomes less prone to such issues.
