The top 5 DDoS attacks

As part of our DDoS theme this week on the Hyve blog and social media, we’ve been looking at how DDoS attacks work and how businesses can protect themselves against them.

DDoS attacks can be targeted at anyone, whether your website creates revenue or not. It isn’t always about financial gain, but often about disrupting normal service and operations and making a statement.

DDoS attacks do vary in size, but the larger attacks have been more prevalent in recent years. With the emergence of attacks such as Low Orbit Ion Cannons (LOIC), DDoS attacks can often be coordinated remotely to attack the same target.

What are some of the biggest reported DDoS attacks?

  • GitHub – 1.35 TBPS
    In 2018, Github, the popular developer platform, was hit with a sudden burst of traffic that hit 1.35 terabits per second. It is currently the largest recorded DDoS attack to date. The traffic was said to have been traced back to over a thousand autonomous systems. The DDoS attack caused intermittent outages, but GitHub was prepared on the most part and was able to divert traffic. They have since deployed additional capacity at their facilities.
  • Occupy Central – 500 GBPS
    In 2014 Hong Kong-based political movement, Occupy Central, was hit by a DDoS attack of 500 gigabits per second. They were targeted because of their political affiliations and attackers sent large amounts of traffic to three of their web hosting services and independent sites. The attack hit servers with packets that were disguised as legitimate traffic and was carried out by 5 botnets.
  • Cloudflare – 400 GBPS
    In 2014 Cloudflare was hit by a 400 gigabits per second DDoS attack. It was directed at one Cloudflare customer and was targeting servers in Europe. The attack was launched by taking advantage of a vulnerability in the Network Time Protocol (NTP), which is a networking protocol for computer clock synchronization. The attack affected Cloudflare’s own network, even though it was only directed at one of their customers.
  • Spamhaus – 300 GBPS
    In 2013 Spamhaus was hit by a DDoS attack which took their website offline as well as their email services. The attack hit their servers with 300 gigabits of traffic per second and was traced back to a member of a Dutch company called Cyberbunker.
  • US banks – 60 GBPS
    In 2012 six US banks were targeted in a series of DDoS attacks, including Bank of America, JP Morgan Chase and PNC Bank. The DDoS attack hijacked hundreds of servers and all created peak floods with more than 60 gigabits of traffic per second. The attackers tried multiple methods to execute the attack until they managed to achieve their goal.

With the size and number of DDoS attacks rising, there will undoubtedly be further larger attacks as time goes on. Businesses must prepare themselves and prevent DDoS attacks affecting their business by implementing a strong security system and DDoS Defence.
