A public interest group called Cybermalveillance is focusing on personal data breaches this year during "Cybermois," a cybersecurity awareness campaign held every October for 14 years. According to the group’s third barometer on the French perception of cyber issues, conducted with Ipsos Digital, nearly half of the French population has now experienced a personal data breach. In 2025, only 30% of people were aware of such a breach, but this number has risen to 45% in 2026. Cybermalveillance plays a key role in helping victims, preventing risks, and monitoring digital threats to anticipate future challenges. The scale of the issue remains unclear, but the increase in reported data breaches to the CNIL (France's data protection authority) suggests the problem is growing. Some companies have released rankings that highlight France's vulnerability to cyber threats, but these rankings are not universally agreed upon. The CNIL had already warned about large-scale data breaches in 2024, and more recently, the ANSSI (National Cybersecurity Agency of France) noted a "major change" in the nature of cyber threats and has reallocated its resources to address these new challenges. Cybermalveillance expects the number of affected individuals to continue rising in the coming months. To address this, the group is launching a new practical guide titled "Personal data breaches, what to do in 3 key steps." The guide, which will be available to the public starting October 1st, provides a step-by-step list of actions to take from the moment of a breach to 30 days later. It includes advice on protecting oneself and strengthening daily cybersecurity practices, aiming to help people both respond to and prevent future incidents. According to the survey conducted by Cybermalveillance, many people have already taken steps to improve their security, such as being more cautious about suspicious communications, changing passwords, and closely monitoring their bank accounts. However, the group emphasizes that more work is needed to ensure that all citizens adopt these good practices and are better prepared for the ongoing threat of data breaches.
