Telegram App Targeted in DDoS Cyberattack

Telegram App Targeted in DDoS Cyberattack

An DDoS attack aimed at slowing connectivity for the Telegram app took place this week. The cyberattack coincided with large protests in Hong Kong, and with most of the IP addresses coming from China, it is speculated that they were involved in the attack.

The Telegram messaging app was overloaded by a DDoS cyberattack this week. The attack was performed in order to flood the app with so much traffic that it slowed users’ connectivity – it was not an attempt to steal users’ data.

The attack coincided with large protests in Hong Kong over an extradition bill with China. Many of the protesters were said to have been communicating over the Telegram app, as there are ways to encrypt messages end-to-end to ensure privacy. Because of this strenuous encryption, the app has been used in terrorist attacks as communication previously, and was the subject of an Iranian government controversy last year.

Pavel Durov, the founder of Telegram, said in a tweet that the IP addresses mostly came from China and consisted of 200-400 Gb/s of clutter.

“Historically, all state actor-sized (attacks) we experienced coincided in time with protests in Hong Kong,” Durov said. “This case was not an exception.”

The attack did not only affect Asia though, but any country that was using the app. The company said in a tweet that the Americas and some users from other countries may experience connection issues.

Paul Bischoff, a privacy advocate at Comparitech.com, said that Durov has good reason to suspect China is the reason for this DDoS attack.

“Telegram CEO Pavel Durov isn’t crazy for suspecting the Chinese government is targeting Telegram,” Bischoff said. “It wouldn’t be the first time that China has weaponized botnets – a group of computers that can be controlled from a single command and control point – to target websites with DDoS attacks.”

Bischoff said in 2015, the largest DDoS attack in history up to that point was attributed to China. The attack was aimed at two censorship circumvention tools hosted on the Github site.

    As the 30th anniversary of the IP camera approaches in 2026, it is worth reflecting on how far we have come. The first network camera, launched in 1996, delivered one frame every 17 seconds—not impressive by today’s standards, but groundbreaking at the time. It did something that no analog system could: transmit video over a standard IP network. Read Now

  • From Surveillance to Intelligence

    Years ago, it would have been significantly more expensive to run an analytic like that — requiring a custom-built solution with burdensome infrastructure demands — but modern edge devices have made it accessible to everyone. It also saves time, which is a critical factor if a missing child is involved. Video compression technology has played a critical role as well. Over the years, significant advancements have been made in video coding standards — including H.263, MPEG formats, and H.264—alongside compression optimization technologies developed by IP video manufacturers to improve efficiency without sacrificing quality. The open-source AV1 codec developed by the Alliance for Open Media—a consortium including Google, Netflix, Microsoft, Amazon and others — is already the preferred decoder for cloud-based applications, and is quickly becoming the standard for video compression of all types.
