Explore the 2025 Verizon DBIR with insights from 12,000+ breaches, highlighting ransomware trends, third-party risks, and BYOD vulnerabilities.
The Verizon Data Breach Investigations Report – 2025 offers a comprehensive analysis of the evolving cybersecurity landscape, based on over 22,000 security incidents and 12,000+ confirmed breaches across 139 countries.
Let’s rewind to the start of 2025. Organizations across every sector like healthcare and retail were navigating a world where ransomware didn’t just encrypt data — it crippled operations, and where attackers no longer needed to phish — they simply walked in through unpatched devices and leaked secrets.
In this blog, we will dissect the trends and break down the top findings, shifts in attack behavior, and what they mean for security teams today.
For years, the order of initial access methods in breaches remained consistent: stolen credentials topped the list, followed by phishing, and then vulnerability exploitation. In a shift, vulnerability exploitation overtook phishing as the second most common initial access method in breaches.
According to the report, 20% of breaches began with vulnerability exploitation, marking a 34% increase over the previous year. Attackers leverage edge device vulnerabilities, VPN flaws, and zero-day exploits to gain access.
The 2025 DBIR makes it clear: third-party risk is no longer a peripheral issue — it’s central to modern breach exposure.
Breaches involving partners, vendors, and service providers have doubled year over year, increasing from 15% to 30%, with this trend cutting across all industries. A key concern is the exploitation of edge devices — such as VPNs, firewalls, and management interfaces — often made possible due to poor vendor hygiene, unpatched vulnerabilities, or default configurations.
The Snowflake attack illustrates the complexity of modern third-party risk. Although Snowflake, as a third-party service provider, itself wasn’t directly breached, attackers accessed customer environments by using stolen credentials and taking advantage of the lack of enforced multi-factor authentication (MFA) on the platform. This transformed a credential management issue into a third-party platform breach with wide impact.
Even though customers might feel the need to outsource some of their operations to third-party vendors for cost advantages, they must control the policies around identity security, inline threat protection, micro-segmentation, patching and visibility and exposure management.
Ransomware continues to dominate the breach landscape in 2025, appearing in 44% of all confirmed breaches, up significantly from 32% last year.
While the median ransom payment fell to $115K and 64% of organizations refused to pay, the story changes dramatically when you look at small and medium-sized businesses (SMBs).
According to the 2025 DBIR, 88% of SMB breaches involved ransomware. Why are SMBs such attractive targets? Because many lack the layered defenses, segmentation, and recovery readiness seen in larger organizations.
Credential misuse still remains the top access vector — but the nature of credential exposure is evolving. 46% of compromised business credentials came from non-managed (BYOD) devices. This reinforces the need for device policies and enforcement that must extend beyond the corporate perimeter for both managed and unmanaged devices.
The DBIR 2025 noted that the growing security risk posed by non-managed (BYOD) devices — which accounted for 46% of corporate credential exposure, compared to just 30% from managed devices.
This insight suggests a shift in focus: rather than just expanding detection capabilities, security teams must prioritize device trust enforcement, BYOD governance, and micro-segmentation in their Zero Trust strategy.
Attackers are moving faster, operating more quietly, and leveraging scalable, low-cost techniques that often go undetected until it’s too late. The human element remains a consistent vulnerability that plays a core role in the majority of breaches.
Meanwhile, sensitive data continues to move into public repositories, and third-party platforms, once viewed as trusted, are now points of failure. Even Generative AI, while delivering productivity benefits, is reshaping risks by lowering the barrier for phishing, deepfakes, and social engineering. Most importantly, the report reinforces that security cannot be one-size-fits-all — every industry faces unique risks that demand tailored strategies.
