Description

On January 10, 2022, the Municipality of Trezzano sul Naviglio experienced a confirmed cyberattack targeting its information systems. The attack compromised servers and machines, necessitating extensive data and document recovery efforts. Municipal officials promptly reported the incident to Italy’s Postal Police and notified the Data Protection Authority (Garante per la protezione dei dati personali) in compliance with regulatory obligations. While the attack caused technical damage to infrastructure, the administration confirmed no data exfiltration or permanent loss of documents occurred. Mayor Fabio Bottero attributed this resilience to prior investments in cloud-based storage solutions, which housed most municipal data externally and allowed services to remain operational despite disruptions. Minor delays in administrative functions were acknowledged, though critical citizen-facing services avoided full interruption. Restoration work involved recovering affected systems over an unspecified period following the attack, with no evidence suggesting ongoing adversary presence post-containment.

The incident underscored the municipality’s reliance on cloud infrastructure investments initiated during Bottero’s previous administration term, which minimized operational downtime and data loss risks. These preemptive measures aligned with the Italian Digital Agency (AGID) guidelines for public administration security standards. In response to the attack, Trezzano sul Naviglio announced additional investments to further secure technical office operations, emphasizing agility and data protection enhancements. The administration reiterated its commitment to cloud-based service qualification and infrastructure hardening, framing the attack as part of a broader trend targeting governmental entities. No specific threat actor, attack vector, or financial impact details were disclosed publicly. Post-recovery operations focused on restoring full system functionality without revising the previously established cloud migration strategy.
