Ransomware Threatens South Asia's Critical Infrastructure

Executive Summary

In early 2026, South Asia has witnessed a significant escalation in ransomware attacks targeting critical infrastructure sectors, including power grids, water systems, industrial control systems (ICS), healthcare, and the financial sector. These attacks have been primarily attributed to sophisticated ransomware groups such as Qilin and Royal (also known as BlackSuit), which have demonstrated advanced tactics and a strategic focus on high-impact targets.

Ransomware Groups Targeting Critical Infrastructure

Qilin, a cybercriminal organization, has been active since January 2025, deploying Linux-based ransomware binaries on Windows hosts by exploiting legitimate remote management and file transfer tools. This group has affected over 700 victims across 62 countries, with a significant concentration in developed markets and high-value industries, including manufacturing, technology, financial services, and healthcare.

Royal, also known as BlackSuit, has been active since 2022 and has targeted a wide range of industries, including healthcare, finance, and critical infrastructure. The group employs aggressive tactics, including double extortion, where compromised data is both encrypted and exfiltrated. Ransom demands typically range from $1 million to $10 million in Bitcoin.

Impact on South Asia's Critical Infrastructure

The surge in ransomware attacks has had a profound impact on South Asia's critical infrastructure:

• Power Grids and Water Systems: Attacks on industrial control systems have disrupted operations, leading to power outages and water supply interruptions. The reliance on legacy SCADA protocols, which were designed decades ago, has exposed vulnerabilities that are being actively exploited by threat actors. (theboard.world)

• Healthcare Sector: Healthcare organizations have been prime targets, with ransomware attacks leading to data breaches and operational disruptions. The All India Institute of Medical Sciences in New Delhi experienced a significant cyber attack in 2023, resulting in the loss of outpatient and research data. (stimson.org)

• Financial Sector: Financial institutions have faced increased ransomware threats, with attacks leading to data exfiltration and operational disruptions. The rise in ransomware attacks targeting critical industries globally has been noted, with a 34% year-over-year increase in such attacks between January and September 2025. (mbtmag.com)

Recommendations for Mitigation

To address the escalating ransomware threat to critical infrastructure in South Asia, the following measures are recommended:

1. Enhanced Cyber Hygiene: Organizations should implement robust cybersecurity practices, including regular software updates, strong access controls, and comprehensive employee training to recognize phishing attempts.

2. Incident Response Planning: Develop and regularly update incident response plans to ensure a swift and coordinated response to ransomware incidents.

3. Collaboration and Information Sharing: Engage in information sharing with industry peers and government agencies to stay informed about emerging threats and effective mitigation strategies.

4. Investment in Security Infrastructure: Allocate resources to strengthen security measures, including network segmentation, intrusion detection systems, and regular security audits.

Conclusion

The rise in ransomware attacks targeting critical infrastructure in South Asia underscores the need for a proactive and coordinated approach to cybersecurity. By implementing comprehensive security measures and fostering collaboration, organizations can enhance their resilience against these evolving threats.
