As soon as the G7 summit in Évian-les-Bains began, the region became the target of a coordinated cyberattack. Several websites of municipalities and public institutions in Haute-Savoie were temporarily accessible in a limited way or were even offline at times on June 15. Among those affected are Annecy, Thonon-les-Bains, Évian-les-Bains, and Saint-Gingolph. These incidents once again illustrate that international meetings are no longer played out only on diplomatic and security levels, but also in the digital space.
The attack was claimed by the pro-Russian hacker group NoName057(16), which, since the beginning of the Russian aggression war against Ukraine, has repeatedly distinguished itself by attacks against state institutions and public infrastructures in Western countries. The group primarily uses so-called DDoS attacks. In this context, servers are overloaded with an enormous number of requests, making websites or online services inaccessible. Unlike conventional attacks aimed at data theft, the goal here is to disrupt the availability of digital offerings.
According to available information, the consequences in Haute-Savoie have remained limited. There is currently no indication of data leaks, manipulations, or intrusions into internal information systems. The attack apparently had primarily a symbolic character. The attackers used the international attention focused on the G7 summit to demonstrate their capability and generate media coverage.
The fact that the region around Lake Geneva was targeted hardly surprises security experts. Major political events have long been considered prime targets for cyberattacks. This type of action often causes limited technical damage but produces a strong political and media impact. They aim to create a climate of insecurity, mobilize security authorities, and give the impression that public institutions are vulnerable.
This development reflects a fundamental change in modern geopolitical conflicts. Digital attacks are now an integral part of international power projection. Previously, protests or demonstrations marked the public perception of summits, but virtual attacks are increasingly taking center stage. Hacktivist groups often act at the intersection of political messaging and technical sabotage.
The incident in Haute-Savoie will therefore be remembered less for its immediate consequences and more as a new example of the growing interconnection between global politics and cyberspace. International summits will now need to be protected not only by police forces and intelligence services but also by digital security specialists capable of repelling invisible attacks against critical infrastructure.
