France Assesses Major Cyberattack on National Tax Administration Amid Opposition Claims of Historic Severity

On Monday, French Prime Minister Sébastien Lecornu chaired an interministerial crisis cell to assess a large-scale cyberattack targeting the national tax administration (fisc). The opposition has described the incident as 'the most serious in the country's history.' A Senate inquiry commission may be established to investigate the breach. No specific technical details, such as attack vectors, compromised systems, or data impacts, were disclosed in the report. The government has not confirmed the opposition’s characterization of the attack’s severity.
