Hacktivist Attacks on Critical Infrastructure in Latin America: A Rising Threat

Introduction

In recent years, Latin America has witnessed a surge in cyberattacks targeting critical infrastructure, with hacktivist groups at the forefront of these operations. These attacks have disrupted essential services, highlighting vulnerabilities in sectors such as energy, water, healthcare, and finance.

Recent Incidents

• Costa Rica (April 2022): The Conti ransomware group initiated a series of attacks against nearly 30 government institutions, including the Ministry of Finance and the Costa Rican Social Security Fund (CCSS). The CCSS experienced significant disruptions, with hospitals reporting system anomalies and the need to shut down critical systems. (en.wikipedia.org)

• Colombia (September 2023): A significant ransomware attack impacted 20 public entities, with 78 additional public entities and 762 private companies affected across Latin America. This attack disrupted vital services, underscoring the region's cybersecurity vulnerabilities. (batuta.com)

Hacktivist Groups Involved

Hacktivist groups, motivated by political or social causes, have been identified as primary perpetrators:

• Guacamaya: An international group operating mainly in Central and Latin America, Guacamaya has targeted major corporations and governments in countries such as Chile, Colombia, El Salvador, Guatemala, Mexico, and Peru. Their operations often involve leaking sensitive information to the public. (en.wikipedia.org)

• CyberArmyofRussia_Reborn (CARR): In January 2024, CARR claimed responsibility for manipulating water storage tanks in Texas, USA, and water utilities in Poland, demonstrating the group's capability to target critical infrastructure. (trustwave.com)

Tools and Techniques

Hacktivist groups employ various tools and techniques to execute their attacks:

• Ransomware: Malware that encrypts data, demanding payment for decryption keys. The Conti group, for instance, used ransomware to disrupt Costa Rican government systems. (en.wikipedia.org)

• Distributed Denial-of-Service (DDoS) Attacks: Overwhelming systems with traffic to render them inoperable. The group NoName057(16) has executed DDoS attacks against critical infrastructure in Europe. (eurojust.europa.eu)

• Exploitation of Vulnerabilities: Targeting unpatched systems to gain unauthorized access. CARR's manipulation of water storage tanks in Texas involved exploiting vulnerabilities in human-machine interfaces. (trustwave.com)

Impact on Critical Infrastructure

The consequences of these attacks are profound:

• Energy Sector: Disruptions can lead to power outages, affecting millions and causing economic losses.

• Water Systems: Manipulation of water treatment processes can compromise water quality, posing public health risks.

• Healthcare: Attacks on healthcare systems can delay medical procedures, endanger patient lives, and erode public trust.

• Financial Sector: Disruptions can lead to financial losses, erode consumer confidence, and destabilize markets.

Regional Cybersecurity Landscape

Latin America's cybersecurity infrastructure faces significant challenges:

• Lack of Preparedness: Only seven of the 32 Latin American countries have plans to protect their critical infrastructure from cyberattacks, and only 20 have Computer Security Incident Response Teams (CSIRTs). (batuta.com)

• High Attack Volumes: In December 2025, organizations in Latin America experienced an average of 3,065 cyberattacks per week, a 26% increase year-over-year. (blog.checkpoint.com)

Recommendations

To mitigate the risks posed by hacktivist attacks on critical infrastructure, the following measures are recommended:

• Strengthen Cybersecurity Frameworks: Develop and implement comprehensive cybersecurity strategies at national and organizational levels.

• Enhance Incident Response Capabilities: Establish and regularly update incident response plans to ensure swift and effective reactions to cyber incidents.

• Promote Public-Private Collaboration: Encourage information sharing and collaboration between government agencies and private sector entities to bolster collective defense mechanisms.

• Invest in Cybersecurity Education: Provide training and resources to develop a skilled cybersecurity workforce capable of addressing emerging threats.

Conclusion

Hacktivist groups pose a growing threat to critical infrastructure in Latin America. Proactive measures, including strengthening cybersecurity frameworks, enhancing incident response capabilities, and fostering collaboration, are essential to safeguard vital services and maintain public trust.
