Around 450 million cyberattacks blocked during the Tokyo Games


The Tokyo Olympics and Paralympics saw around 450 million cyberattacks when held this summer, but Games disruption was avoided as all attempts were blocked, organizers said on Tuesday.

Despite fears that the global sporting event might be an easy target for hackers, the scale of the attacks at the Tokyo Games was less than that of the London 2012 Games and the Pyeongchang 2018 Winter Olympics.

Trend Micro Inc., a large internet security firm, said the low number of cyberattacks was likely due to the Tokyo Olympics going without spectators amid the coronavirus pandemic, which meant tickets and other information for visitors could not be used maliciously.

“We were able to prevent cyber attacks without causing damage. This is the result of information sharing and countermeasures taken by all parties concerned, ”said the Tokyo Games Organizing Committee.

From the opening of the Olympics on July 23 to the closing of the Paralympics on September 5, around 450 million cyber attacks targeting the official website and the organizing committee system were blocked, according to organizers and other sources.

Although details of cyber attacks are unknown, the majority are believed to have been distributed denial of service attacks or DDoS attacks, in which hackers overwhelm networks by sending floods of data from multiple sources over a short period of time. of time.

The London Olympics saw the most confirmed cyberattacks on record, with the official site alone targeted around 200 million times, and attacks on all associated organizations totaling around 2.3 billion.

During the Pyeongchang Olympics, around 600 million cyberattacks were attempted. Tokyo faced an even greater threat than the London Olympics, but only saw around 20%.

The government’s National Incident Preparedness and Cyber ​​Security Strategy Center said that while there were also several unauthorized sites posing as video feeds for the opening ceremony and competitions, and posts on the networks social calls for cyber attacks, the functioning of the Games was not affected.
