Brazil temporarily disabled its national emergency alert system following a suspected cyberattack that sent false “Extreme Alert” messages to citizens overnight. The unsolicited notifications disrupted residents and prompted an immediate investigation by the Civil Defense agency and Federal Police. Authorities believe the alerts were remotely triggered by an unauthorized party, indicating a security breach. The system will remain offline until security vulnerabilities are addressed and preventative measures are implemented. The incident raises concerns about the vulnerability of critical infrastructure to cyber threats. Officials have not yet identified the source of the attack or the extent of compromised data, if any. The focus is currently on restoring a secure and reliable alert system for public safety.
