The Securityish Brief
On December 19, 2025, La Poste, the National Postal Service of France, fell victim to a large-scale Distributed Denial of Service (DDoS) attack. This cyberattack severely disrupted postal and parcel delivery services, which are critical during the busy Christmas holiday season. The attack also impacted La Banque Postale, leading to significant online banking service disruptions for many customers.
Preliminary investigations indicate that the attack may have been executed by state-sponsored hackers, with suspicions pointing towards Russian-linked cybercriminals or individuals from China. The timing of the attack is particularly concerning, as cybercriminals often exploit the holiday season when many organizations operate with reduced staff, making it harder for IT security teams to respond effectively.
In a separate incident, Romania’s National Water Agency reported a ransomware attack that compromised over 1,000 systems, including critical infrastructure for monitoring drinking water supplies. This attack, executed using BitLocker encryption software, has severely impacted the agency’s operations, raising concerns about public health and safety.
The Romanian National Cyber Security Directorate (DNSC) has indicated that the ransomware attack is sophisticated, and there are fears that sensitive data may have been stolen. The targeting of an agency responsible for national infrastructure underscores the severity of the situation and the potential for widespread disruption.
These incidents reflect a broader trend of increasing cyberattacks on critical infrastructure worldwide.
