Overview
- The Superior Tribunal Militar detected an outage compatible with a cybersecurity incident on Thursday, July 2, and immediately took the public portal offline to protect systems.
- STM technical teams isolated affected systems, blocked external access as a preventive step, and began detailed analysis and recovery procedures under internal security protocols.
- The court reported the incident to police and intelligence agencies and those authorities have opened investigations into the cause and origin of the disruption.
- STM says there are so far no signs that institutional or procedural data were leaked, but officials have given no timeline for a full service restoration and will update the public only after technical confirmation.
- The outage follows a wider series of cyberattacks on Brazilian public bodies in 2025–2026, including past DDoS operations that led to police actions, and the prolonged portal downtime could hinder public access to military-justice information and services.
