Verizon DBIR Report reveals software vulnerabilities now cause more breaches than stolen passwords, while ransomware and AI-driven attacks.

Verizon DBIR Report Reveals Software Vulnerabilities Are Now the Top Cause of Data Breaches

The latest Verizon DBIR Report highlights a major shift in the cybersecurity landscape. For years, stolen passwords and credential abuse were considered the most common methods used by cybercriminals to gain access to corporate systems. However, the newest findings show that software vulnerabilities have now become the leading cause of security breaches.

The report provides valuable insights into how cyber threats are evolving and why organizations need to rethink their cybersecurity strategies in 2026.

Software Vulnerabilities Overtake Stolen Credentials

According to the Verizon DBIR Report, exploitation of software vulnerabilities accounted for 31% of all security incidents analyzed during the study period. In comparison, credential abuse represented only 13% of incidents.

This shift indicates that attackers are increasingly targeting unpatched software flaws rather than relying solely on stolen usernames and passwords. As organizations deploy more applications, cloud services, and connected systems, the number of vulnerabilities requiring attention continues to grow.

Cybersecurity experts warn that delayed patching creates opportunities for threat actors to exploit known weaknesses before organizations can fix them.

Why Organizations Struggle With Vulnerability Management

The Verizon DBIR Report emphasizes that vulnerability management remains one of the most important cybersecurity practices. However, many organizations face significant challenges when attempting to patch critical vulnerabilities quickly.

Verizon noted that companies often have thousands of vulnerabilities to evaluate, prioritize, and remediate. Limited resources, staffing shortages, and complex IT environments make the process even more difficult.

Perhaps most concerning, only 26% of critical vulnerabilities were fully remediated by organizations in 2025. This represents a 12-percentage-point decline compared with the previous year.

The findings suggest that many businesses are falling behind in their efforts to secure critical systems, increasing their exposure to cyberattacks.

Ransomware Continues to Grow

The Verizon DBIR Report also found that ransomware remains one of the most significant threats facing organizations worldwide.

Ransomware was involved in 48% of all reported breaches, up from 44% in the previous year. Despite the increase in attacks, ransom payments continue to decline.

Nearly 70% of ransomware victims chose not to pay attackers. Among organizations that did make payments, the median ransom amount was $139,875, down from $150,000 the year before.

Security analysts believe improved backup strategies, stronger incident response planning, and increased law enforcement cooperation are helping organizations resist ransom demands.

How Cybercriminals Are Using Artificial Intelligence

Artificial intelligence is becoming an increasingly important tool for cybercriminals. The Verizon DBIR Report reveals that threat actors are experimenting with AI throughout multiple stages of cyberattacks.

Attackers are using AI to:

• Identify potential targets
• Discover software vulnerabilities
• Develop malware
• Improve phishing campaigns
• Automate attack processes
• Increase operational efficiency

Verizon researchers found that the median threat actor used AI assistance across 15 documented attack techniques. Some advanced groups leveraged AI in as many as 40 to 50 different techniques.

Researchers have also observed a growing amount of AI-assisted code appearing in malware and other offensive security tools heading into 2026.

What This Means for Businesses

While AI is helping cybercriminals operate more efficiently, the Verizon DBIR Report indicates that AI is not yet creating entirely new categories of cyber threats. Instead, it is accelerating existing attack methods and making them more scalable.

For businesses, this means cybersecurity fundamentals remain as important as ever. Organizations should focus on:

• Prioritizing critical vulnerability patching
• Implementing strong access controls
• Conducting regular security assessments
• Training employees to recognize cyber threats
• Strengthening ransomware preparedness
• Monitoring emerging AI-powered attack techniques

Companies that improve their vulnerability management processes will be better positioned to reduce cyber risk and defend against increasingly sophisticated attacks.

Conclusion Verizon DBIR Report

The Verizon DBIR Report highlights a significant change in modern cybersecurity. Software vulnerabilities have surpassed stolen credentials as the primary cause of security breaches, while ransomware and AI-assisted attacks continue to evolve.

As cyber threats become faster and more automated, organizations must prioritize patch management, strengthen security operations, and adapt to an increasingly complex threat environment. Businesses that fail to address critical vulnerabilities promptly may face greater risks in the years ahead.
