Ransomware Attack on The Steamship Authority

CRITICAL-92
STE319092125
In June 2021, The Steamship Authority suffered a ransomware attack that encrypted critical network files, rendering systems inoperable. The attack disrupted core operations, including the inability to process or modify reservations (vehicle, passenger, or ticketing) both online and via phone. Customers faced significant delays, and transactions were limited to cash due to compromised credit card systems. While vessel safety remained unaffected—radar and GPS functions stayed operational—the operational paralysis caused financial strain, reputational damage, and logistical chaos. The attack forced reliance on manual processes, severely degrading service efficiency and customer trust. No explicit mention of data exfiltration was reported, but the systemic outage directly threatened the organization’s revenue streams and public perception.
