French authorities said on Tuesday that more than 140 cyberattacks were reported during the Paris Olympics, but none of them disrupted the competitions. In the run-up to and during the Olympic Games, the French cybersecurity agency was on high alert for attacks that could disrupt the organizing committee, ticketing or transport. Between July 26 and August 11, the government cybersecurity agency Anssi recorded 119 reports corresponding to low-impact “security events” and 22 incidents in which “a malicious actor” successfully targeted a victim’s information system. The attacks mainly targeted government entities, as well as sports, transport and telecommunications infrastructure, the agency said.
According to Anssi, a third of these were downtime incidents, half of which were due to denial-of-service attacks designed to overload servers.
The other cyber incidents were related to attempted or actual compromise and disclosure of data, among others.
“All cyber events that occurred during this period were generally characterized by their low impact,” said Anssi.
The Grand Palais, which hosted Olympic events in Paris, and around 40 other museums in France were victims of a ransomware attack in early August, but it did not affect any of the information systems involved in the games, according to Anssi.
Ransomware exploits security flaws to encrypt and lock computer systems, demanding a ransom from a user or organization to unlock them.
During the pandemic-postponed Tokyo Olympics held in 2021, organizers reported 450 million such operations, double that of the 2012 London Olympics.
Ahead of the Paris Olympics, Marie-Rose Bruno, director of technology and information systems for the Paris Games, said she expected “eight to 10 times more” cyberattacks than those seen at the Tokyo Games.
