Brazil’s Healthcare Sector Faces Alarming Cyber Threats: Health-ISAC Calls for Enhanced Information Sharing Solutions

Health-ISAC has raised an urgent alarm about the rising cyberattacks in Brazil’s healthcare sector. They emphasize the need for better information sharing to protect patient data and essential infrastructures. This limited exchange leaves the system vulnerable to various threats, as highlighted in their report focusing on global patient care resilience. Members from over 140 countries are coming together to share vital information that can help regions facing pressing cyber risks.

The recent report, titled ‘Brazilian Critical Infrastructure Threat Landscape and Implications for Healthcare Organizations’, digs into the complex relationship between geopolitical factors and healthcare security. It notes that fragmented care systems and increased data centralization create ripe conditions for cyberattacks, specifically from both cybercriminals and state-sponsored groups.

“Ransomware attacks are disrupting hospital operations and sensitive medical data is at risk,” said Errol Weiss, Health-ISAC’s chief security officer. “This report provides crucial guidance to help healthcare entities navigate these evolving threats.”

Diego Mariano, security lead at Hospital Israelita Albert Einstein, echoed this sentiment, noting that the cybersecurity landscape is becoming increasingly complex. “The growing threats outpace our preparedness. We need to act together,” he said. These insights are especially valuable for Brazilian healthcare organizations that lack access to critical knowledge.

Denise Anderson, president and CEO of Health-ISAC, emphasized that sharing intelligence is key to safeguarding healthcare systems. “We must strengthen our connections globally to enhance our resilience,” she said.

To further this mission, Health-ISAC is hosting a workshop on September 9th in São Paulo, aimed at building relationships and sharing best practices among health security leaders.

Brazil’s healthcare system faces unique challenges. There’s a stark divide between rural and urban areas, leading to increased violence against healthcare workers. With data centralized in large stores, these systems are prime targets for cybercriminals. Financially motivated actors often focus on healthcare because disruptions can have serious impacts on patient care.

Additionally, petty crime, like copper theft, disrupts essential services, while political unrest is likely to rise ahead of Brazil’s 2026 elections. Protests and strikes are expected to escalate, creating further risks for ongoing healthcare operations.

Despite a low risk of terrorism, isolated threats do linger. Police have interrupted several plots in recent years, showing that while major incidents are rare, the potential still exists.

The report also points to climate change as a growing threat, with severe weather affecting transportation and utilities. Droughts and heavy rains can cause significant disruptions and damage infrastructure.

Brazil has become a hotspot for cybercrime. Health-ISAC points out that the country’s weak enforcement against cybercriminals has allowed various domestic syndicates to flourish. “These groups exploit weak cybersecurity measures for financial gain,” the report notes. Ransomware attacks have been particularly damaging, affecting both public and private sectors.

A recent trend on social media highlights growing concerns about health data security. Users are more aware of the risks, leading to discussions about better protection measures. This awareness is crucial, as organizations face mounting pressure to safeguard sensitive information.

Reports from Health-ISAC indicate that the number of cyber incidents in healthcare has surged over the past year. While ransomware attacks dipped briefly in late 2024, they have since surged again, underlining a persistent threat to the sector.

In response, Health-ISAC has issued over 220 alerts to members regarding vulnerabilities that could be exploited. This proactive approach aims to help security teams fix issues before they lead to attacks.

As Brazil’s healthcare sector grapples with these challenges, the emphasis on cybersecurity is more vital than ever. Safeguarding patient data and systems is essential for ensuring that healthcare can continue to operate effectively in the face of evolving threats.
