Brazil has temporarily suspended its **Civil Defense Alert** system after a suspected cyberattack triggered a series of false emergency warnings across multiple states. The incident, which occurred early Saturday, saw at least a dozen unauthorized alerts disseminated through the platform, which is typically used to notify residents about critical threats like floods and landslides. According to a statement from Brazil’s **National Protection and Civil Defense Secretariat**, the rogue alerts included the word "misanthropy" and were issued at the system's highest emergency level. This caused mobile phones to emit loud alarm sounds, even when set to silent mode. ### Widespread Impact and Investigation The unauthorized messages were reported in various regions, including São Paulo, Rio de Janeiro, Paraná, Mato Grosso do Sul, and the Federal District. Authorities are currently unable to determine the exact number of devices that received these messages, as the alerts were activated outside official protocols. In response, officials have temporarily halted the alert platform and blocked external access to its **Public Alert Dissemination Interface**, the mechanism responsible for distributing emergency notifications. Brazil's **Ministry of Integration and Regional Development** stated that there is no evidence of "structural damage" to the core Civil Defense Alert infrastructure. The **Federal Police** have launched an investigation into the unauthorized access, which officials believe was "responsible for the deliberate sending of messages with inappropriate content unrelated to real events." ### Attack Vector and Future Plans Preliminary findings indicate that attackers issued 10 unauthorized alerts. Nine of these were sent using the cell broadcast technology inherent to the Civil Defense Alert system, while a tenth was distributed via SMS. Authorities have not yet identified a suspect but confirm that the alerts were remotely triggered by an individual not affiliated with the national civil defense network. A timeline for the system's restoration has not been provided. **Wolnei Wolff**, National Secretary of Protection and Civil Defense, confirmed that a more secure version of the platform is already under development and will be activated as soon as possible. "We are handling the case with the utmost technical rigor. Our commitment is to ensure that the alert systems function with complete reliability, guaranteeing the protection of the Brazilian population," Wolff stated. The **Civil Defense Alert** system is designed to provide critical, real-time warnings for severe storms, floods, and landslides. It delivers text and audio notifications directly to compatible mobile phones without requiring prior registration and can override silent mode during life-threatening emergencies.
