Ransomware Attacks Hit Record Highs in Q3 2025: What Houston Businesses Need to Know

The cybersecurity threat facing businesses has reached unprecedented levels. Q3 2025 saw ransomware attacks continue their relentless climb, with 270 publicly disclosed incidents representing a 36% increase compared to the same period in 2024. For Houston businesses and organizations across Texas, these statistics paint a troubling picture of the evolving cyber threat environment.

What makes these numbers even more alarming is what they don’t show. Behind every publicly reported attack are roughly six incidents that never make the news. An estimated 1,510 ransomware attacks went unreported during the same quarter, meaning that nearly 85% of all ransomware incidents stay hidden from public view. This reporting gap creates a false sense of security and prevents businesses from understanding their true risk exposure.

 Key Trends from Q3 2025:

The latest ransomware data reveals critical patterns that every business owner must understand to protect their organization. The numbers paint a clear picture of who’s being targeted, how attacks are evolving, and where the greatest risks lie.

• Healthcare organizations bore the brunt of attacks, experiencing 86 incidents that accounted for 32% of all publicly disclosed ransomware activity, making it the most targeted sector for the quarter
• Government and technology sectors each reported 28 attacks, and together with healthcare, these three industries represented more than half of all disclosed incidents during Q3
• Manufacturing led undisclosed attacks with 22% of cases, followed by the services sector with 333 incidents, while construction entered the top three targeted industries for the first time with 143 attacks
• Data exfiltration has become the weapon of choice for ransomware groups, with 96% of all disclosed cases involving data theft, marking the highest rate recorded to date
• 54 different ransomware groups were linked to attacks during the quarter, with Qilin emerging as the most active for the second consecutive quarter, claiming responsibility for 20 disclosed incidents and 242 undisclosed attacks
• Approximately 40% of reported attacks remain unattributed to any known group, suggesting either new players entering the space or established groups operating under different identities
• The United States accounted for 68% of disclosed attacks with 184 incidents and 54% of undisclosed attacks with 817 incidents, making it by far the most targeted nation
• Organizations in 93 countries worldwide reported ransomware incidents, demonstrating the truly global nature of this threat and the need for vigilant cybersecurity regardless of location
• The average data volume exfiltrated across 449 dark web victim listings where details were available reached 527.65GB, showing the massive scale of information theft occurring in modern attacks

These patterns underscore a critical reality for managed IT support providers serving Houston and surrounding areas like Katy: proactive cybersecurity measures are no longer optional but essential for business survival in today’s threat environment.

 The Evolution of Ransomware Tactics:

Modern ransomware has evolved far beyond the simple encryption attacks of the past. Today’s cybercriminals employ sophisticated strategies that make traditional defenses inadequate and force organizations to fundamentally rethink their security approaches.

• Attackers now focus on data exfiltration first, recognizing that stolen information provides irreversible leverage even if victims maintain strong backup systems and can restore encrypted files
• The integration of AI accelerates ransomware operations, automating deception techniques, improving social engineering attacks, and magnifying psychological pressure on defenders to pay ransoms quickly
• Rather than simply encrypting files and demanding payment for decryption, criminals steal sensitive information first and use the threat of public exposure, regulatory penalties, and competitive disadvantage as primary leverage points
• Organizations must now focus on detecting signs of exfiltration including unusual outbound traffic, anomalous MFA behaviors, and sudden file movement patterns, because by the time systems are encrypted the damage is often already done
• Only 3% of undisclosed cases included an upfront ransom demand, as gangs increasingly prefer to negotiate directly with victims after establishing they have valuable stolen data
• Ransomware groups are targeting specific geographic regions and industry sectors with coordinated campaigns, reusing the same attack playbooks across multiple similar organizations once they identify successful entry points
• The emergence of 18 new ransomware groups during Q3 demonstrates how the ransomware-as-a-service model and affiliate networks enable rapid scaling of attacks without requiring deep technical expertise
• The human toll extends beyond financial costs, with security teams experiencing burnout, organizational morale suffering, and psychological strain weakening resilience long after technical systems are restored
• The “internal blast radius” of ransomware represents hidden costs that many businesses fail to account for when assessing cybersecurity posture, including employee attrition, lost institutional knowledge, and reduced defensive capabilities

The shift from encryption-focused to exfiltration-focused attacks fundamentally changes what effective defense looks like, requiring businesses to implement comprehensive monitoring, layered security architecture, and rapid incident response capabilities that address both technical and human dimensions of cyber threats.
