Verizon's 2026 Data Breach Investigations Report records 1,492 healthcare incidents and 1,438 confirmed data disclosures. Vulnerability exploitation is the leading initial-access vector at 20%, followed by phishing, stolen credentials, and employee error. A third of healthcare breaches now involve a third-party vendor.

Verizon's 2026 Data Breach Investigations Report (DBIR), published in May 2026, records 1,492 healthcare incidents and 1,438 confirmed data disclosures over the reporting window. Across all sectors the report covers 31,000+ incidents and 22,000 confirmed breaches in 145 countries; the healthcare cut is one of the report's longest-running industry breakdowns.

The leading initial-access vectors in healthcare are vulnerability exploitation (20%), phishing (14%), stolen credentials (11%), and employee errors (11%). Ransomware drove 48% of breaches across all sectors, up from 44% in the 2025 report. The median ransom paid fell to $139,875 from $150,000, and 69% of victims did not pay.

Third parties now feature in 32% of healthcare breaches, against 48% across all industries combined. The human element (phishing, misdelivery, misconfiguration, loss) was involved in 54% of healthcare incidents, with misdelivery the largest single component at 40%.

Vulnerability remediation remains the weakest link. Only 26% of critical vulnerabilities were fully remediated in 2025, with a median time to resolution of 43 days. For a sector in which ransomware operators routinely exploit known unpatched vulnerabilities, the gap between disclosure and remediation is the operational problem underlying the headline incident count.
