Verizon Business's 2025 Data Breach Investigations Report identifies credential abuse and vulnerability exploitation as the leading attack vectors in over 12,000 confirmed data breaches. Key findings include a doubling of third-party involvement in breaches, which now accounts for 30%, and a 34% increase in vulnerability exploitation. Ransomware incidents surged 34%, although the amount paid in ransoms decreased. The report also highlights the overlapping nature of human error linked to social engineering and emphasizes the urgent need for improved security measures to combat these evolving threats.
The 2025 DBIR findings demonstrate that the exploitation of vulnerabilities as the initial access vector for breaches has seen another year of growth, reaching 20%. Edge device vulnerabilities grew nearly eight-fold.
Third-party involvement in breaches has doubled to 30%, and espionage-motivated breaches rose significantly to 17%. Additionally, 46% of compromised systems with corporate credentials were non-managed devices.
