Hackers could have full access (!) to everything on the phones of WhatsApp users.

This was possible through a security issue disclosed by WhatsApp itself last week. All a hacker had to do to control your phone was send you a malicious video or start a video call with you on WhatsApp.

You are probably thinking "Yeah, but if I updated WhatsApp to the latest version, I am safe, right"?

Not really.

A WhatsApp security issue exactly like this one was discovered in 2018, then another in 2019 and yet another one in 2020 (tap each year's link to see the corresponding vulnerability). And yes, in 2017 before that. Prior to 2016, WhatsApp didn't have encryption at all.

Every year, we learn about some issue in WhatsApp that puts everything on their users' devices at risk. Which means it's almost certain that a new security flaw already exists there. Such issues are hardly incidental – they are planted backdoors. If one backdoor is discovered and has to be removed, another one is added (read the post "Why WhatsApp will never be secure" to understand why).

It doesn't matter if you are the richest person on earth – if you have WhatsApp installed on your phone, all your data from every app on your device is accessible, as Jeff Bezos found out in 2020. That's why I deleted WhatsApp from my devices years ago. Having it installed creates a door to get into your phone.

I'm not pushing people to switch to Telegram here. With 700M+ active users and 2M+ daily signups, Telegram doesn't need additional promotion. You can use any messaging app you like, but do stay away from WhatsApp – it has now been a surveillance tool for 13 years.

As promised, we've launched the ability to buy Telegram usernames on a dedicated platform – Fragment. Auctions for the most valuable usernames are already live, so make sure to check it out. In a few days, we will also introduce the ability for users to sell their existing usernames on Fragment.

For the first time in the history of social media, a fair, transparent market for usernames is established. Finally people will have ownership over their social media addresses, secured in the immutable ledger of a decentralized blockchain network.

This is just the beginning, and yet an important milestone – the power has started to shift into users' hands.

Some content creators started using third-party payment bots to sell access to individual posts in their Telegram channels. This way, content creators could receive close to 100% of whatever their subscribers paid, which was great.

Unfortunately, we received word from Apple that they were not happy with content creators monetizing their efforts without paying a 30% tax to Apple. Since Apple has complete control over its ecosystem, we had no alternative but to disable such paid posts on iOS devices.

This is just another example of how a trillion-dollar monopoly abuses its market dominance at the expense of millions of users who are trying to monetize their own content. I hope that the regulators in the EU, India and elsewhere start taking action before Apple destroys more dreams and crushes more entrepreneurs with a tax that is higher than any government-levied VAT.

In the meantime, we at Telegram shall work to offer creators powerful and easy-to-use tools to monetize their content – outside of Apple's restrictive ecosystem.

I feel particularly excited about today’s Telegram update. It adds topics to large groups, transforming these linear chats into slick mobile-friendly versions of good old Internet Forums.

Ironically, the very first popular internet service I built around 20 years ago was also an Internet Forum – a message board for students of my university, which eventually grew into the biggest student portal in the region.

16 years ago I again incorporated forums into the Communities section of VK, a social network I founded. Since VK was the most popular communication platform in Russia, Ukraine, Kazakhstan and other countries, tens of millions of people used the forum feature there.

I feel nostalgic about those times: I had yet to learn the skill of hiring engineers and designers back then, so I programmed and designed everything on my own, working 20 hours per day.

Today I am fortunate to have the best coding team in the world to recreate the forum experience for hundreds of millions across all platforms in a more modern, fast and accessible form. Telegram will now support organized conversations where thousands of people can concurrently discuss different subjects in the same group.

Topics today come packed with lots of features – including the ability to close and pin topics, flexible notification options and lots of fun animated emoji to be used as topic icons. But this is just the start. Taking advantage of the two-week delay caused by Apple’s review, we have begun to expand these new threaded groups into something even more powerful.
