Introduction
The cybersecurity landscape is undergoing a major shift, and the latest findings from Verizon’s Data Breach Investigations Report (DBIR) highlight a turning point that security teams can no longer ignore. For nearly two decades, stolen credentials have dominated as the primary way attackers gain access to systems. However, the newest data shows a dramatic reversal. Vulnerability exploitation has now taken the lead, signaling that attackers are increasingly prioritizing technical weaknesses over traditional identity-based intrusion methods. This change reflects both the growing complexity of modern IT environments and the rising pressure on organizations struggling to keep up with patch management and vulnerability remediation.
Summary of the Original Report
According to Verizon’s DBIR, vulnerability exploitation has become the most common initial access vector in data breaches for the first time in almost 20 years. The report is based on extensive analysis of real-world incidents, law enforcement inputs, and threat intelligence collected globally. In the past year, 31 percent of data breaches began with attackers exploiting software vulnerabilities, a significant jump from 20 percent in the previous year. This shift pushed vulnerability exploitation ahead of compromised credentials, which dropped sharply from 22 percent to 13 percent as an entry point.
The report suggests that attackers may be accelerating their discovery and use of vulnerabilities, potentially with the assistance of AI-driven tools that help identify exploitable flaws faster than before. However, Verizon also emphasizes a more grounded issue: organizations are not patching known vulnerabilities quickly enough. Only 26 percent of critical vulnerabilities listed in CISA’s Known Exploited Vulnerabilities catalog were fully remediated in 2025, a decline from 38 percent the year before.
This slowdown is happening while the total volume of vulnerabilities has increased significantly, with organizations facing 50 percent more critical issues than in the previous reporting period. Security leaders argue that the real challenge is prioritization, not just detection. Teams are overwhelmed by the number of vulnerabilities and struggle to determine which ones pose real, exploitable risk.
Experts also point out that manual remediation processes are becoming unsustainable. Some advocate for AI-assisted remediation systems that combine automation with human oversight to improve response speed and accuracy.
AI is also increasingly present in attacker behavior. The report notes that threat actors used AI assistance across multiple attack techniques, sometimes dozens of times within a single campaign. Meanwhile, “shadow AI” usage inside companies has surged, becoming the third most common non-malicious insider activity in data loss prevention systems.
Employee interaction with AI tools has also expanded significantly, with nearly half of workers using both managed and unmanaged AI applications on corporate devices. This widespread adoption is introducing new visibility and governance challenges.
Social engineering remains highly effective, especially on mobile platforms, where phishing success rates are significantly higher than email-based attacks. Verizon reports that mobile-based phishing clicks are 40 percent more successful than email attempts, highlighting how user behavior shifts across devices.
The human factor continues to dominate breach statistics, appearing in 62 percent of incidents. Supply chain attacks are also rising sharply, increasing by 60 percent year over year and now accounting for nearly half of all breaches.
In third-party environments, security weaknesses remain widespread, particularly around multi-factor authentication and misconfigured cloud permissions. Many organizations take months to remediate these issues, leaving extended exposure windows for attackers.
Ransomware incidents have also increased slightly as a proportion of breaches, but most victims, around 69 percent, are refusing to pay ransom demands, indicating growing resilience and improved recovery strategies across industries.
What Undercode Say:
The shift from credential-based attacks to vulnerability exploitation marks a structural evolution in cybercrime economics. Attackers are no longer relying primarily on stolen identities because identity security has improved through MFA adoption and monitoring systems. Instead, they are shifting toward weaker operational layers: unpatched systems, outdated software, and misconfigured infrastructure. This is a more scalable and often more reliable entry point.
The 31 percent statistic is particularly significant because it shows that vulnerability exploitation is not just increasing, but overtaking a long-standing dominant method. This suggests a maturing attacker ecosystem where automation, scanning tools, and AI-assisted discovery are reducing the cost of finding exploitable systems.
The decline in credential abuse from 22 percent to 13 percent indicates that defensive investments in identity security are beginning to pay off. MFA, passwordless authentication, and behavioral monitoring are creating friction for attackers who previously relied on phishing or credential stuffing.
However, the improvement in identity security has unintentionally shifted pressure onto vulnerability management teams. Organizations are now overwhelmed by the sheer volume of CVEs and critical patches. The report’s finding that only 26 percent of critical KEV vulnerabilities were fully remediated shows a dangerous backlog.
This backlog creates a widening attack surface window. Every unpatched vulnerability represents a potential entry point, and attackers increasingly target known exploited vulnerabilities rather than zero-days because they are faster to weaponize.
The 50 percent increase in critical vulnerabilities adds another layer of complexity. Security teams are not just failing to keep up, they are actively falling further behind due to system sprawl, cloud adoption, and software dependency chains.
Prioritization becomes the core issue. Not all vulnerabilities are equal, yet many organizations still treat them as a flat backlog. Attackers, however, selectively chain vulnerabilities that lead to privilege escalation, lateral movement, or ransomware deployment.
AI’s role on both sides is emerging as a force multiplier. Attackers are using AI to identify patterns, generate exploits, and accelerate reconnaissance. Meanwhile, defenders are only beginning to adopt AI for remediation workflows, and often without full governance models in place.
Shadow AI usage inside enterprises creates a parallel risk layer. Employees using unmanaged AI tools can expose sensitive data without malicious intent, expanding the attack surface in unpredictable ways.
Mobile phishing success rates highlight a behavioral gap. Users are more cautious on email but more relaxed on SMS or voice channels, which attackers exploit through social engineering.
The rise of supply chain breaches to nearly half of all incidents signals systemic dependency risk. Organizations are only as secure as their weakest vendor, and third-party MFA misconfigurations show how fragile that ecosystem remains.
Ransomware trends show a subtle but important behavioral shift. Even though incidents are rising, refusal to pay at 69 percent indicates stronger backup strategies, legal pressure, and improved incident response maturity.
Overall, the data suggests a transition from identity-centric attacks to infrastructure-centric exploitation, driven by automation, scale economics, and delayed patching cycles.
Fact Checker Results
✔ Verizon DBIR reports vulnerability exploitation at 31 percent of breaches
✔ Credential abuse dropped significantly compared to previous year data
✔ Supply chain breaches and ransomware trends align with reported industry patterns
Prediction
Vulnerability exploitation will continue to grow as the dominant breach entry point unless organizations dramatically reduce patch latency and improve automated remediation.
AI-assisted attack tooling will further compress the time between vulnerability disclosure and real-world exploitation.
Supply chain security failures will become the next major amplification point for large-scale breaches over the coming years.
