In recent years, a growing number of individuals and websites have taken it upon themselves to track and report data breaches, often alerting the public to potential leaks before official announcements. Sebastien, known online as Seblatombe, regularly posts on X about suspected data thefts and has amassed nearly 20,000 followers. In August, he warned about a significant data leak from the tax office before the Ministry of Economy officially announced it. Similar efforts are being made by others, such as Thomas Lazzaroni, who runs cyberattaque.org and monitors alerts on platforms like Facebook. Christophe Boutry, the creator of Fuitesinfo.fr, has a notable background as a former police officer from the DGSI. However, he was sentenced to seven years in prison in 2025 for corruption after selling information on the darknet. Aeris, a data privacy activist and creator of bonjourlafuite.eu.org, also aims to raise public awareness about data leaks. These individuals and websites claim to inform the public about data breaches, but their methods have raised concerns. Vincent Strubel, director general of the National Agency for Information System Security (Anssi), noted that more than half of the alerts received by the institution in 2025 were unverified. Sebastien and others claim to verify their claims by consulting extracts of databases published by hackers and contacting Anssi and targeted organizations. However, some organizations have indicated that initial reports were inaccurate, later corrected on the FrenchBreaches website. The issue of engaging with hackers is also debated. Sebastien discusses with hackers to "request certain information" and has published interviews with some of these individuals. Thomas Lazzaroni, however, claims to speak to hackers "very little." Aeris refuses to highlight the crimes of hackers who contact him directly. Christophe Boutry criticizes the rush to publish information quickly, arguing that this can come at the expense of accuracy and quality. Despite the controversy, these individuals and websites play a significant role in keeping the public informed about data breaches. However, the challenge remains in balancing the need for transparency with the responsibility to ensure the accuracy of the information shared. As the debate continues, it is clear that the landscape of data security and public awareness is evolving rapidly.
