Description
On the early week of July 2025, the official website of the Prefeitura de Dourados in Mato Grosso do Sul became inaccessible due to a cyber incident that disrupted citizen access to the municipal network domains. The municipality confirmed the incident in a note sent to Security Report on July 1, 2025, stating that the portal had been taken offline at the beginning of the week. According to the communiqué, residents were initially unable to consult the Diário Oficial, the Sistema Cidadão that manages public services, the previdenciary system, and the distance education platforms operated by the Secretaria de Assistência Social and the Instituto do Meio Ambiente. The note indicated that the Prefecture expected the portal to resume operations also on that Tuesday.
By the time of the statement, some of the affected systems had already been restored to allow access, although portions of the site continued to display a security warning when users attempted to reach the domain. The message accompanying the warning did not specify the nature or motivation of the cyber incident, nor did it clarify whether citizen data had been preserved or if any authorities had been contacted. Engineers and technicians from the Prefecture’s Department of Information Technology were reported to be evaluating the extent of the damage caused by the invasion of the portal and working to reestablish the connection with the address www.dourados.ms.gov.br. No further technical details about the attack vector or mitigation steps were provided in the released information.
The Prefecture emphasized that no prejudice would be inflicted on citizens as a result of the disruption and that any deadlines for submitting documents or providing information in ongoing administrative processes would be extended accordingly. It reiterated its expectation that the portal would be fully recovered during the course of that Tuesday. The communication concluded with a reminder that the municipal IT team remained engaged in restoring services and monitoring the situation.
