Telegram, the encrypted instant messaging tool, experienced powerful cyber attacks yesterday (June 12) that caused disruptions for users on the the same day that tens of thousands of young people took to the streets of Hong Kong to protest against a controversial extradition bill.

One of the tools that organizers have turned to is the encrypted messaging service, Telegram, and other secure messaging technologies as they look to bypass surveillance measures by government officials.

The messaging platform Telegram which was founded in 2013 by two Russian brothers, Nikolai and Pavel Durov, and has often been used by activists and others seeking to avoid the monitoring of their communications.
This isn’t the first time that someone has tried to take down Telegram at a time when China was experiencing significant unrest. Four years ago, a similar attack struck the company’s service, just as China was initiating a crackdown on human rights lawyers in the country.
