System outage disrupts operations at Brazil's Port of Santos

Freshplaza • November 11, 2026

An information system outage at Brazil's Port of Santos, which began on November 6, has disrupted port procedures and prompted increased security measures. Authorities are investigating a possible cyberattack and extortion attempt.

According to A Tribuna, the disruption followed a power fluctuation and affected identification systems, access controls, and digital tools used in port operations. Suspected hackers reportedly demanded payment to restore services, although authorities have not confirmed a cyberattack or unauthorized data access.

The outage caused delays in vessel, truck, and train movements, with several automated procedures transferred to manual processing. Approximately 80 per cent of administrative employees were reportedly working remotely.

On November 8, Cesportos-SP raised port security to Level 2, allowing increased police presence and additional security measures.

The Santos Port Authority (APS) confirmed that its website, internal systems, and customer services had been affected. However, vessel arrivals and departures, as well as landside access, remain operational.

APS has introduced contingency procedures and reinforced Port Guard teams. Specialists from Brazil's Federal Data Processing Service (Serpro) are assisting with system restoration and forensic investigations.

The authority acknowledged that delays could occur but stated that no services had been suspended.
