France’s Ministry of the Interior has confirmed that its email servers were the target of a cyberattack that impaired internal communications. The ministry said it discovered the incident after irregular activity was detected on its messaging infrastructure. Officials stated that the attack affected some internal email services and prompted immediate defensive measures to contain the activity and assess the impact.
Authorities said the incident did not involve a ransomware demand. Instead, the attackers appear to have gained unauthorised access to components of the email system, leading the ministry to take affected servers offline. The decision to disconnect systems was described as a necessary step to prevent further intrusion and to protect information held within the broader network.
The ministry did not disclose full details about the scope of data accessed or the technique used by the attackers. It said that an investigation is underway with support from national cyber defence agencies. Officials added that the priority is to restore secure communication channels and to determine the extent of any compromise.
The French government emphasised that some operational disruption was expected as a result of the incident. Internal communications using the affected email services were temporarily limited, and alternative systems were used to maintain essential functions. The ministry said it is working to reestablish full service as quickly as possible.
Cybersecurity analysts said that attacks on government messaging infrastructure can have significant implications for administrative continuity. Internal email systems are critical for coordination among departments and agencies, and disruption can slow routine operations. Experts also noted that such attacks often precede broader campaigns targeting sensitive institutional systems.
The ministry reassured the public that no sensitive external systems were affected and that services relied on by citizens, such as public safety communications, continued to operate normally. It said that the incident has not disrupted direct communication with the public or the delivery of core services.
French authorities stated that they are cooperating with specialised national agencies to analyse the attack. The government has a dedicated cyber defence apparatus tasked with responding to significant incidents affecting state institutions and critical infrastructure. Officials said they will apply additional hardening measures to the email environment and review current security protocols in light of the attack.
The incident underscores ongoing challenges faced by public sector organisations in defending messaging and collaboration platforms. Government agencies worldwide have reported similar attacks in recent years, highlighting the need for robust monitoring, timely detection and coordinated response capabilities. Analysts said that rapid containment and transparent communication are key elements of effective incident response when public institutions encounter cyber threats.
The ministry said it will provide updates as the investigation progresses and more information becomes available. Authorities reaffirmed their commitment to maintaining the security and integrity of government networks.
