Macaé Municipality

Profile narrative

Macaé Municipality is the local government authority for the city of Macaé, located in the state of Rio de Janeiro, Brazil. As a municipal administration, it is responsible for managing public affairs and delivering services to the resident population. The organization operates from its headquarters in Macaé and performs the functions assigned to municipal administrations under Brazilian law. While the specific portfolio of services is not detailed in the source, the municipality is known to have maintained COVID‑19 vaccination operations, indicating a role in public health initiatives. Its activities are guided by municipal legislation and it interacts with state and federal agencies as part of Brazil’s federative system.

In June 2023, the municipality experienced a ransomware attack that targeted its internal network, compromising file servers, systems, and databases through suspected local vectors such as USB drives or VPN connections. The infection rendered most internal systems inoperable, although public‑facing services continued to function without interruption. Responding to the incident, Macaé Municipality isolated the affected equipment, launched a forensic analysis, and filed a police cybercrime report while also pursuing legal action against the perpetrators. The attack corrupted data, notably affecting tax exemption protocol records, which required the municipality to reach out directly to impacted taxpayers for re‑submission of information. Despite the disruption, the organization continued its COVID‑19 vaccination efforts and announced plans to modernize its IT infrastructure, including the adoption of enhanced security measures. No dedicated leak site published details of the breach, and the municipality has since focused on strengthening its cyber resilience as part of its ongoing IT modernization program.
