While Brazil and the world are still struggling to contain the Coronavirus contagion, a new epidemic is spreading across the planet and has already reached the country:\u00a0that of hacker attacks on city halls<\/strong>. Since the end of last year,\u00a0systems of more than 30<\/strong>\u00a0municipalities, for example, Campos dos Goytacazes (RJ), Tabo\u00e3o da Serra (SP), Belo Horizonte (MG), Campinas (SP) and others (listed below) were invaded, compromising and paralyzing online and in-person services. Victims include cities of all sizes, demonstrating the automated nature of the software that coordinates these actions.<\/p>\n

Attacks on city halls are mostly of the type ransomware<\/strong>, which is a type of extortion in which cybercriminals hijack and encrypt data from systems and charge a ransom to re-establish access and not disclose the information on the internet. Other hackers target financial systems, which guarantees a better chance of success than a ransom demand.<\/p>\n

According to a Trend Micro survey, the most affected segments, worldwide, in 2019 and 2020, were manufacturing, government<\/strong>, education and health, in that order, and these four sectors were responsible for more than more than\u00a01 million, 463 thousand detections, last year alone<\/strong>.<\/p>\n

In Brazil, the\u00a0government is the main target of cybercriminals<\/strong>, and the sector leads the ranking in the last two years, with 40% of attacks, in 2019, and 35.3% of threats blocked in 2020, with more than triple the detections compared to the second place.<\/p>\n

Brazil has 5,500 municipalities, many with very poor IT management. According to Renato Tocaxelli, Trend Micro's Government Account Manager, with Covid, investments in security were repressed to pay attention to other priorities. \u201cThe accelerated migration to the cloud, aiming at the expansion of online services for citizens, and the remote work of public employees, took place without due attention to the rules of access control and restriction. Cloud computing has basic configurations that generate vulnerabilities and easy attacks\u201d, analyzes Tocaxelli.<\/p>\n

For hackers, city halls are easier and faster sources of income, because the interruption of services quickly creates popular dissatisfaction, pressure against the manager, who often sees no alternative but to pay the ransom.<\/p>\n

Among the vulnerabilities that make city halls a target are:<\/strong><\/p>\n
