A recent cyber breach has given hackers control over the anti-flood pumps in Venice's San Marco system, allowing them to potentially disable defenses and inundate coastal areas. This incident highlights the vulnerability of operational technology (OT) systems, which are crucial for managing critical infrastructure such as flood defenses, energy grids, and water systems. The attack on Venice's flood system demonstrates that OT systems are no longer just responsible for maintaining physical operations, but also for withstanding cyber threats. The failure to secure these systems can have devastating consequences, including disruption of essential services and damage to property and infrastructure1. This incident serves as a reminder that staying informed about security developments is crucial in mitigating potential threats, and that practitioners must prioritize the security of OT systems to prevent such breaches.
