パリ五輪中のサイバー攻撃は１４０件以上、仏当局が発表

【パリＡＦＰ＝時事】フランスのサイバーセキュリティ当局は１３日、パリ五輪期間中に１４０件以上のサイバー攻撃が報告されたが、大会に大きく影響したものは一つもなかったと発表した。（写真は資料写真）
　大会前から大会中を通じて、フランスの国家情報通信システム安全庁（ＡＮＳＳＩ）は組織委員会やチケット発行、交通に悪影響を与え得る攻撃を強く警戒。しかし「この期間中に発生したサイバー事象はすべて、おおむね低影響度と特徴づけられるものだった」と明かした。
　７月２６日から８月１１日にかけて、ＡＮＳＳＩでは影響度の低い「セキュリティ事象」に該当する報告１１９件と、「悪意ある攻撃者」が被害者の情報システムを標的とすることに成功した事件２２件を記録した。攻撃は主に政府の事業者と、スポーツ、交通、通信インフラを標的としたものだったという。
　またパリ五輪の競技会場ともなったグランパレをはじめ、国内約４０の美術館が８月上旬にランサムウェア攻撃の被害に遭ったが、大会関連の情報システムに影響はなかった。
　ランサムウェア攻撃はセキュリティの隙を突いてコンピュータシステムを暗号化してアクセスを阻害し、解除のためのランサム（身代金）を要求する。【翻訳編集ＡＦＰＢＢＮｅｗｓ】

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 runup and throughout the Olympic Games, France's cyber security agency had been on high alert for attacks that had the potential to disrupt the organising committee, ticketing or transport.
Between July 26 and August 11, government cyber security 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 telecoms infrastructure, the agency said.
According to Anssi, a third of those were downtime incidents, half of which were due to denial-of-service attacks designed to overwhelm servers.
The other cyber incidents were related to attempted or actual compromises and data disclosure, among others.
All the cyber events that occurred during this period were generally characterised 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 this did not affect any of the information systems involved in the games, according to Anssi.
Ransomware exploits security flaws to encrypt and block computer systems, demanding a ransom from a user or an organisation to unlock them.
During the pandemic-delayed Tokyo Olympics held in 2021, organisers reported 450 million such operations, twice as many as during the 2012 London Olympics.
Ahead of the Paris Olympics, Marie-Rose Bruno, director of technology and information systems for the Paris Games, had said he expected eight to 10 times more cyber attacks than those seen at the Games in Tokyo.
