Ransomware Attacks on Critical Infrastructure Surge 34% in 2025: Is Your Houston Business at Risk?

The threat level for American businesses has reached unprecedented heights. According to KELA’s recent report “Escalating Ransomware Threats to National Infrastructure,” security researchers documented 4,701 ransomware incidents worldwide between January and September 2025, marking a staggering 34% increase compared to the same period in 2024. What’s more alarming is that half of these attacks specifically targeted critical infrastructure sectors that keep our economy running.

For Houston-area businesses, this isn’t just a distant threat. The manufacturing sector, which forms a significant part of our local economy, experienced the steepest growth with attacks surging 61% from 520 incidents to 838 incidents year-over-year, according to KELA’s analysis. High-profile victims like Jaguar Land Rover and Bridgestone demonstrate how ransomware can paralyze global operations, disrupt supply chains, and create cascading economic damage.

 The Ransomware Threat Has Evolved

What started as financially-motivated digital extortion has transformed into something far more dangerous. Today’s ransomware operators function like professional criminal enterprises, wielding sophisticated tools and tactics that rival nation-state capabilities. These groups don’t just encrypt your data and demand payment anymore. They steal sensitive information first, then threaten to publish it publicly if you don’t pay, a tactic known as double-extortion.

The concentration of attacks tells a sobering story. Out of 103 active ransomware groups observed in 2025, just five criminal organizations accounted for nearly 25% of all global incidents:

Qilin led the pack with 248 documented attacks, followed closely by Clop with 246 incidents, Akira with 209 incidents, Play with 120 incidents, and SafePay with 115 incidents. Together, these five groups were responsible for 938 attacks, while the remaining 98 threat actors carried out the rest. This concentration reveals how organized and efficient modern cybercrime has become.

 Who’s Getting Hit?

The United States remains the epicenter of ransomware activity, accounting for approximately 1,000 incidents, or 21% of all global attacks in 2025. This concentration isn’t accidental. Cybercriminals deliberately target American businesses because of two key factors: our digital dependence creates more opportunities for disruption, and our economic strength means higher potential ransom payments.

The sectors facing the greatest risk include:

• Manufacturing leads with 838 attacks in 2025, representing a 61% increase from 2024. Production facilities, supply chain operations, and just-in-time manufacturing systems create perfect conditions for ransomware disruption.
• Healthcare remains a prime target with attackers exploiting the sector’s life-or-death urgency. Hospital systems, medical device networks, and patient data repositories all present lucrative targets.
• Technology companies face persistent threats as attackers seek intellectual property, source code, and customer data that can be sold or exploited.
• Transportation and logistics operations experience significant attacks as disruptions cascade through interconnected systems.
• Financial services institutions deal with constant threats as cybercriminals pursue both ransom payments and valuable financial data.
• Government and public sector organizations face attacks designed to disrupt essential services and erode public trust.
• Energy sector facilities represent critical infrastructure targets where disruption can affect entire regions.

 The Manufacturing Crisis Hits Home

The 61% surge in manufacturing attacks deserves special attention, particularly for Houston’s robust industrial sector. The incidents at major manufacturers demonstrate how vulnerable even sophisticated operations have become to ransomware disruption.

Key Manufacturing Incidents in 2025:

• Jaguar Land Rover suffered a global shutdown in September 2025, forcing production closures across facilities in the UK, Slovakia, China, India, and Brazil, with the attack claimed by the hacker collective “Scattered Lapsus$ Hunters”
• Bridgestone faced cyberattacks affecting multiple manufacturing facilities in South Carolina and Quebec, with speculation pointing to the same hacker alliance
• Manufacturing sector overall experienced attacks surging from 520 incidents to 838 incidents year-over-year, representing the steepest growth among all sectors
• Supply chain disruptions cascaded through entire industries as interconnected systems failed, affecting vendors, distributors, and customers
• Financial consequences extended beyond ransom demands to include production losses, overtime costs for recovery, and damaged customer relationships

These high-profile breaches underscore how ransomware actors increasingly view manufacturing not just as a means to extort money, but as a path to critical leverage where even brief shutdowns can ripple through entire industries and economies.

 How Attackers Operate

Modern ransomware groups function with frightening efficiency, leveraging sophisticated tools and tactics that rival nation-state capabilities. Understanding their attack methodology helps businesses identify vulnerabilities and implement effective defenses.

The Typical Ransomware Attack Sequence:

• Initial Access comes through phishing emails with malicious attachments, exploited vulnerabilities in internet-facing systems, compromised remote desktop services, or stolen credentials purchased from dark web marketplaces
• Lateral Movement occurs as attackers explore your network to identify valuable data, locate backup systems, and find critical operational systems
• Data Exfiltration happens before encryption, with attackers stealing sensitive information including proprietary data, customer records, financial information, and employee data
• Encryption Deployment strikes simultaneously across multiple systems to maximize impact and prevent response, typically during off-hours or weekends
• Ransom Demand arrives with payment instructions in cryptocurrency, threats to publish stolen data, and deadlines to create urgency
• Double-Extortion Tactics add pressure by threatening to publish sensitive information even if you can restore encrypted data from backups

The double-extortion approach proves particularly effective because solid backups alone no longer provide complete protection. Even organizations that can restore all encrypted data still face the threat of having proprietary information, customer data, or sensitive business records published online.

 The Geographic Threat Pattern

While ransomware affects businesses worldwide, attack distribution reveals clear patterns that help explain why certain regions face disproportionate targeting. Geography matters when understanding your risk profile.

Top Targeted Countries in 2025:

• United States led with approximately 1,000 incidents (21% of all global attacks), reflecting the combination of digital dependence and economic strength that attracts cybercriminals
• Canada experienced 139 incidents, with attackers targeting manufacturing, healthcare, and financial services sectors
• Germany faced 102 incidents concentrated in industrial and technology sectors
• United Kingdom recorded 76 incidents across various critical infrastructure sectors
• Italy saw 74 incidents primarily affecting manufacturing and financial services
• Other regions accounted for the remaining 3,310 incidents distributed across dozens of countries, demonstrating ransomware’s truly global reach

For Houston businesses, this geographic concentration carries important implications. The United States’ position as the primary target reflects both opportunity and vulnerability, with our digital infrastructure, economic strength, and critical industries making us the most attractive target for profit-motivated cybercriminals.

 Why Small and Medium-Sized Businesses Face Special Risk

While headlines focus on attacks against major corporations and government agencies, small and medium-sized businesses face disproportionate risk relative to their security capabilities. The threat environment creates particular challenges for organizations without enterprise resources.

Unique Vulnerabilities of Smaller Organizations:

• Limited Security Resources mean many smaller organizations lack dedicated cybersecurity staff, maintain restricted security budgets, and struggle to compete for security talent
• Outdated Systems persist because upgrade costs seem prohibitive, with legacy applications, unsupported operating systems, and unpatched vulnerabilities creating easy entry points
• Perceived as Easier Targets by cybercriminals who deliberately seek businesses with weaker defenses and less sophisticated detection capabilities
• Higher Relative Impact occurs because a $500,000 ransom and recovery costs that a corporation might absorb could bankrupt a small manufacturer or healthcare provider
• Recovery Costs Beyond Ransom include system restoration, forensic investigation, legal fees, regulatory notification requirements, and lost business during downtime
• Supply Chain Exposure increases as attackers use smaller vendors and service providers as stepping stones to reach larger target organizations

The financial reality hits smaller businesses harder too. Even choosing not to pay the ransom doesn’t eliminate crushing expenses, with total recovery costs often proving catastrophic to organizations operating on thin margins.

 The Ransomware-as-a-Service Ecosystem

Understanding how modern ransomware operates requires recognizing the sophisticated criminal ecosystem that enables these attacks. The professionalization of cybercrime has fundamentally changed the threat environment.

How Ransomware-as-a-Service Operates:

• Core Developers create the malware, maintain infrastructure, and provide the technical foundation for attacks
• Affiliate Programs allow criminals to purchase access and conduct attacks using provided tools, similar to legitimate franchise models
• Revenue Sharing splits successful ransom payments between developers and affiliates, creating aligned financial incentives
• Low Barrier to Entry means attackers no longer need programming skills or deep technical expertise to launch sophisticated campaigns
• Professional Services include encryption algorithms, payment processing, leak sites for stolen data, technical support for victims, and negotiation assistance
• Victim Support Desks maintain professional help systems, provide decryption tools after payment, and offer technical assistance to help victims pay ransoms

This business model dramatically increased attack frequency by making ransomware accessible to less sophisticated criminals. The customer service approach even builds perverse credibility within criminal circles, with some groups developing reputations for actually providing decryption keys after payment.

 What This Means for Network Security

The escalating threat environment demands a fundamental shift in how businesses approach cybersecurity. Traditional perimeter defenses, while still important, no longer provide adequate protection against determined attackers.

Essential Components of Modern Defense:

• Network Segmentation contains lateral movement by isolating critical systems, implementing zero-trust architecture, and controlling access between network zones
• Endpoint Detection and Response identifies suspicious behavior through continuous monitoring, behavioral analysis, and automated threat response
• Regular Security Assessments identify vulnerabilities through patch management, configuration reviews, and penetration testing
• Employee Security Training transforms staff from security vulnerability to human firewall through regular phishing simulations, security awareness programs, and incident reporting procedures
• Offline Backup Systems protect recovery capability with immutable backups that attackers cannot access, encrypt, or delete
• Incident Response Planning minimizes recovery time through documented procedures, practiced scenarios, and established communication protocols
• Managed Security Services provide expertise and resources that exceed what most small and medium-sized businesses can maintain internally

Effective protection requires a layered approach that assumes breaches will occur and focuses on limiting damage. For many organizations, maintaining this level of security internally proves impractical given the expertise required, tools needed, and constant vigilance necessary.
