The victim, an administrative entity encompassing the cities of Marseille, Martigues, and the Aix-Marseille-Provence metropolis, was hit by a ransomware attack. This region, significant for its public services and infrastructure, faced a cyber incident that targeted interconnected information systems across multiple municipalities, including the Grand Port Maritime de Marseille.
According to sources, over the course of a weekend, the public sector's digital infrastructure was compromised by ransomware identified as Mespinoza/Pysa.
As a consequence, networks had to be isolated. The presence of backup and recovery systems have mitigated the damage, averting the worst outcomes. No proven impact was detected on the port’s OT systems.
