Cyber-risks are evolving. Third-party involvement in data breaches and advanced vulnerability exploitation is on the rise. Verizon’s 2025 Data Breach Investigations Report (DBIR) has analyzed over 22,000 incidents and 12,195 confirmed breaches worldwide.
From zero-day exploits targeting perimeter devices to ransomware impacting small businesses, the report gives a clear picture to organizations to reassess their security postures.
Let’s break down the findings, what they mean for cybersecurity, and how businesses should respond.
This year’s report has analyzed multiple worrying trends in how cyberattacks are initiated and spread:
Credential Abuse | 22% of breaches | One of the most common attack methods, involving stolen or misused login credentials. |
Vulnerability Exploitation | 20% of breaches | Attackers exploit known or unknown system flaws, often in unpatched software. |
Third-Party Involvement | 30% of breaches | Breaches tied to vendors or partners doubled, using weak supply chain defenses. |
Ransomware | 44% of breaches (↑ 37%) | High growth, especially among SMBs, with high operational and financial impact. |
Zero-Day Exploitation | 34% increase | Targeting perimeter devices like VPNs shows the speed and sophistication of attackers. |
Human Involvement | Persistent across breach types | Includes phishing, social engineering, and insider misuse of privileges. |

Manufacturing and Healthcare saw a rise in espionage-driven breaches. |
Financial, Retail, and Education sectors continue to face sustained threats. |
Small and Medium-Sized Businesses (SMBs) are the target of ransomware, with 88% of SMB breaches involving ransomware payloads. |
Zero-day attacks are increasingly common, particularly on perimeter devices and VPNs.
Supply chain and partner ecosystem exposures are responsible for one-third of all breaches.
Though the median ransom has dropped to $115,000, the frequency and impact remain high.
Social engineering, phishing, and poor password practices continue to be major contributing factors.
A passive security stance is no longer sufficient today. Verizon’s report clearly shows us that we need a proactive approach:
Ensure that access is continually verified, and segment networks to minimize breach impacts.
Conduct regular vendor assessments, contractually require cybersecurity standards, and monitor supply chain activities.
Prioritize critical updates, especially on perimeter-facing systems, to reduce exposure to zero-day exploits.
Use a combination of endpoint protection, offline backups, and incident response plans to combat ransomware.
Educate staff on social engineering tactics, credential security, and phishing detection.
Although maintaining a strong security posture from inside is important, it is also essential to externally manage the risks:
Here's how you can use Dark Web Monitoring:
Yes. Although companies and individuals have a lower payout ratio, ransomware is still a persistent and low-cost threat.
Third-party breaches often occur through vendors with weak security controls or outdated systems. Attackers use these as a way to target larger targets.
Zero-day attacks affecting edge devices like VPNs, firewalls, and web applications are being exploited commonly due to their broad exposure.
The combination of limited resources, lower cybersecurity maturity, and high ransomware targeting makes SMBs vulnerable.
Businesses need to realign their security fundamentals due to changing cybersecurity threats.
Whether you’re a multinational enterprise or a growing SMB, visibility, vigilance, and rapid response are what you need.
