Telegram Traces Cyber-attack To The Mainland

Encrypted messaging service Telegram suffered a major cyber-attack that originated from China, the company's CEO said on Thursday, linking it to the ongoing political unrest in Hong Kong.

Many protesters in the city have used Telegram to evade electronic surveillance and coordinate their demonstrations against a controversial Beijing-backed plan that would allow extraditions from the semi-autonomous territory to the mainland.

Demonstrations descended into violence Wednesday as police used tear gas and rubber bullets to disperse protesters outside Legco.

Telegram announced on Wednesday that it was suffering a "powerful" Distributed Denial of Service (DDoS) attack, which involves a hacker overwhelming a target's servers by making a massive number of junk requests.

It warned that users in many regions may face connection issues.

Pavel Durov, Telegram's CEO, said the junk requests came mostly from China.

Telegram later announced on Twitter that its service had stabilised. It also posted a series of tweets explaining the nature of the attack.

"Imagine that an army of lemmings just jumped the queue at McDonald's in front of you – and each is ordering a whopper," it said, referring to the flagship product of Burger King.

"The server is busy telling the whopper lemmings they came to the wrong place – but there are so many of them that the server can't even see you to try and take your order."

When asked about Durov's claim the attack originated from China, foreign ministry spokesman Geng Shuang said he was not aware of the incident.

"What I can tell you here is that China has always opposed any form of cyber-attacks. China is also a victim of cyber-attacks," Geng said at a regular press briefing in Beijing. (AFP)
