Distributed Denial of Service attack on Telegram causes service outages

  • The attack caused services outages primarily in South and North America.
  • However, users in the United Kingdom, the Netherlands, Germany, Ukraine, Russia, Australia, and China also faced connection issues and network disruptions.

A Distributed Denial of Service (DDoS) attack on Telegram messenger caused service outages and connection problems for users at certain parts of the world.

Which countries were impacted?

The attack caused services outages primarily in South and North America. However, users in the United Kingdom, the Netherlands, Germany, Ukraine, Russia, Australia, and China also faced connection issues and network disruptions.

“We’re currently experiencing a powerful DDoS attack, Telegram users in the Americas and some users from other countries may experience connection issues,” Telegram tweeted.

What happened?

A network of compromised computers targeted Telegram servers with a DDoS attack. A botnet formed of compromised computers sent huge traffic to Telegram servers which resulted in unstable connections as the messenger could not handle all the requests.

What is a DDoS attack?

In a Distributed Denial of Service (DDoS) attack, multiple compromised systems are used to target a server with a huge volume of traffic. DDoS attack aims at bringing services down by bombarding them with so much traffic that their services and infrastructure are unable to handle it.

On February 28, 2018, GitHub suffered world’s largest DDoS attack that took the service offline from 17:21 to 17:26 UTC and intermittently unavailable from 17:26 to 17:30 UTC.

Source of the attack

Pavel Durov, Founder and CEO of Telegram noted that the DDoS attack has been originated from China.

“IP addresses coming mostly from China. Historically, all state actor-sized DDoS (200-400 Gb/s of junk) we experienced coincided in time with protests in Hong Kong (coordinated on @telegram). This case was not an exception,” Durov tweeted.

Connection problem resolved

Telegram confirmed users that their data are safe. “There’s a bright side: All of these lemmings are there just to overload the servers with extra work – they can’t take away your BigMac and coke. Your data is safe,” Telegram tweeted.

As of now, the connection issues have been resolved and users will be able to use Telegram messenger without any disruptions.

What is Firewall? A Firewall is a network security device that monitors and filters incoming and outgoing network traffic based on an organization's previously established security policies. At its most basic, a firewall is essentially the barrier that sits between a private internal network and the public Internet.

 

Secure your network at the gateway against threats such as intrusions, Viruses, Spyware, Worms, Trojans, Adware, Keyloggers, Malicious Mobile Code (MMC), and other dangerous applications for total protection in a convenient, affordable subscription-based service. Modern threats like web-based malware attacks, targeted attacks, application-layer attacks, and more have had a significantly negative effect on the threat landscape. In fact, more than 80% of all new malware and intrusion attempts are exploiting weaknesses in applications, as opposed to weaknesses in networking components and services. Stateful firewalls with simple packet filtering capabilities were efficient blocking unwanted applications as most applications met the port-protocol expectations. Administrators could promptly prevent an unsafe application from being accessed by users by blocking the associated ports and protocols.
