On March 25, 2025, the official website of the Brazilian Navy was taken offline, marking another cyberattack by the hacker Azael. The attack disrupted access to key public services, official publications, and transparency content, raising concerns about vulnerabilities in critical state systems. Azael, who previously targeted entities like Petrobras and the Superior Federal Court (STJ), claimed responsibility for the breach on online forums and social media. While the exact cause of the outage remains unclear, reports of system instabilities align with previous claims made by the hacker.
This cyberattack on the Brazilian Navy’s website is part of a broader wave of attacks targeting Brazil’s strategic institutions, including the Air Force (FAB) and Petrobras.
The hacker’s actions raise serious concerns about systemic flaws in the nation’s digital security infrastructure. Although the Navy’s website has been down indefinitely, there is still no confirmation on whether sensitive data was leaked or internal systems compromised. This attack highlights a growing pattern of directed assaults on critical national infrastructures, threatening both public and private sector security.
The Brazilian authorities have not yet issued an official statement regarding the attack, but cybersecurity agencies, including the Army’s Cyber Defense Center (CDCiber) and the Federal Police, are investigating. Experts fear that these incidents may expose deeper, structural vulnerabilities in Brazil’s governmental systems, particularly within Defense, Justice, and critical infrastructure sectors. Such cyberattacks not only damage public trust but could also serve as entry points for more extensive breaches of internal networks, posing greater risks to national security.
The incident underscores the urgent need for a unified cybersecurity strategy in Brazil, an area that has long been neglected.
Without a comprehensive, binding national policy on cybersecurity, Brazil remains vulnerable to both external and internal cyber threats. Experts argue that a lack of proper investment, outdated systems, and fragmented security measures put the country at a significant disadvantage in the digital age. The increasing frequency and severity of attacks emphasize the necessity for a coordinated, strategic response to safeguard national sovereignty in the cyber domain.
