Ransomware Becomes a Weapon of National Disruption
Ransomware has evolved from a corporate nuisance into a full-scale national security threat. According to KELA’s National Cybersecurity Report: Ransomware, attacks surged 34% year-over-year between January and September 2025. Nearly half of these attacks targeted critical infrastructure sectors, including manufacturing, healthcare, energy, transportation, and finance. Lin Levi, Threat Intelligence Team Lead at KELA, said, “Ransomware operations should be understood not solely as financially motivated attacks but also as tactical instruments capable of disrupting victim operations.”
U.S. Hit Hardest by Global Ransomware Wave
The United States accounted for 21% of all ransomware incidents worldwide, facing roughly 1,000 attacks. Canada, Germany, the U.K., and Italy followed as major targets. KELA noted that attackers seek both financial gain and strategic leverage, targeting wealthy, digitally dependent nations.
“These attacks test the resilience of industries central to U.S. national security and global supply chains,” the report stated. The geographic concentration underscores ransomware’s dual purpose: economic exploitation and strategic disruption.
Manufacturing Under Siege
Manufacturing experienced the sharpest escalation, with attacks soaring 61% year-over-year, from 520 to 838 incidents. The report cited the global shutdown of Jaguar Land Rover and Bridgestone’s production disruptions as examples of how ransomware can paralyze operations and ripple through economies.
The manufacturing sector’s dependence on interconnected systems and legacy technology makes it a prime target for cyberattacks. KELA’s analysis aligns with IBM’s X-Force 2025 Threat Intelligence Index, which also names manufacturing the top-targeted industry for four consecutive years.
Few Groups, Major Impact
Just five ransomware groups — Qilin, Clop, Akira, Play, and SafePay — accounted for nearly 25% of all attacks in 2025. Together, they executed 938 incidents out of a total of 4,701 recorded globally. These groups use Ransomware-as-a-Service models and double-extortion tactics to scale operations across borders.
KELA emphasized that this concentration demonstrates the professionalization of cybercrime. The report stated, “Organized cybercrime groups now operate with the reach, resources, and coordination once attributed primarily to nation-state adversaries.”
Critical Sectors Bear the Brunt
Half of all global ransomware incidents targeted critical sectors that underpin modern societies. Healthcare, technology, energy, and transportation systems all experienced increasing attacks. The report referred to these industries as “the backbone of national resilience.”
The consequences extend beyond economics. Disruptions in healthcare threaten patient safety, while attacks on transportation cause cascading effects across logistics and supply chains. Financial sector breaches shake public trust and market stability.
Economic and Strategic Fallout
Ransomware now undermines national economies and public confidence. KELA’s findings describe how attacks on manufacturing and finance “cripple production lines, disrupt trade, and erode market confidence.” This erosion of trust challenges governments’ ability to protect citizens and maintain operational continuity.
The report noted that ransomware has become a strategic weapon—a tool to destabilize nations as much as to extract ransom payments. It concluded, “Repeated successful attacks erode trust in government and the private sector’s ability to protect critical infrastructure.”

Cyber Resilience: A National Imperative
KELA’s report calls for public–private collaboration to strengthen cyber resilience. It urges:
- Real-time intelligence sharing to detect and disrupt ransomware campaigns.
- Sector-specific resilience standards for healthcare, energy, and transportation.
- Investment in incident response and recovery capabilities to reduce downtime.
- International cooperation to dismantle cross-border cybercrime infrastructure.
“With 50% of all ransomware attacks in 2025 targeting critical infrastructure, the message is clear,” KELA warned. “Cyber resilience is now a matter of national defense.”
The Growing Professionalization of Cybercrime
KELA identified 103 active ransomware groups in 2025. Most are small-scale operators, but a few dominate global activity. These organizations resemble corporate entities, complete with customer service channels, affiliate programs, and marketing arms. The Cyber Insurance News Podcast recently delved into this topic; you can find it here.
Their business model thrives on scale. Phishing-as-a-Service and ransomware marketplaces lower the barrier to entry. The result is a global ransomware economy that operates with industrial precision.

A Borderless Threat
While the U.S. remains the top target, ransomware’s reach is global. Over 70% of incidents occurred outside major economies. The attacks affected sectors from agriculture to aerospace, highlighting how ransomware exploits digital interdependence worldwide.
KELA observed that ransomware is “borderless, opportunistic, and adaptive.” Even smaller economies are facing the fallout, as digital supply chains now link every sector and nation.
Analogy: Ransomware as a Digital Wildfire
Ransomware today resembles a digital wildfire that’s sparked by small embers but spreading rapidly through connected systems. Each compromised endpoint is dry brush waiting to ignite. Once the fire catches, it spreads through global supply chains, scorching economies and eroding trust. Just as communities invest in fire prevention, nations must invest in cyber resilience.
