December 2025 cyberattack breaching AWS infrastructure, affecting 9.5M patients Stolen data includes PII, SSNs, medical histories, billing, and insurance information across 20+ clients No dark web leaks confirmed; credit monitoring offered, marking 2ndlargest healthcare breach of 2026 American healthcare technology company Aesto Health suffered the second-largest confirmed healthcare data breach of the year so far, having lost data on more than 9.5 million patients.

In mid-December last year, the company suffered a cyberattack. Now, more than half a year later, it reported the incident to the HHS Office for Civil Rights, detailing what was lost, from whom, and what the extent of the incident is. Aesto Health is an Alabama-based healthcare technology business, whose core service is helping other healthcare firms manage medical data, change electronic health record systems, and similar. As per its
announcement, the attack affected parts of its Amazon Web Services (AWS) infrastructure, which unidentified threat actors managed to access between December 2 and December 18.

Health Medical Group, and many others.

In the attack, the company lost personally identifiable information (PII) of its clients patients, including full names, Social Security numbers (SSN), partial dates of birth, drivers license numbers, state identification
numbers, financial account numbers, taxpayer identification numbers, health records, medical histories, claims/billing information, and health insurance information.

This is more than enough information for cybercriminals to launch highly sophisticated phishing and vishing attacks, which can result in disruptive ransomware and millions of dollars in damages. Luckily, there is still no evidence the data leaked on the dark web, or that it was already used by
other criminals.

Aesto Health is now offering credit monitoring and identity theft protection services to everyone affected by the breach. Are you a pro?
