Cyber Attack Disrupts Porto de Santos Digital Systems

Overview

• The Autoridade Portuária de Santos said its website and internal platforms were taken offline after a power outage on Friday and that a cyber incident is under investigation.
• The Polícia Federal opened an inquérito and Serpro plus external vendors are conducting forensic analysis to define the scope of the intrusion and whether any data were accessed.
• Basic services such as internet and telephony were restored on Monday while the APS continues to recover systems from backups and run administrative tasks through the federal Porto Sem Papel system.
• Cesportos‑SP raised the port protection level to 2, port security teams increased inspections and biometric access and some administrative processes moved to manual controls, causing delays for users and truckers.
• Security officials say a hacker group calling itself N0n claimed responsibility but that the claim is unverified, and the case highlights a broader rise in cyberattacks on critical infrastructure in 2026.
