Threat Risk: High
Victim: Aesto Health and affiliated healthcare providers
Incident: Unauthorized access and exfiltration of data from AWS infrastructure.
Impact: Theft of PII and PHI belonging to over 9.5 million individuals.

Analysis: The breach targeted Aesto Health’s cloud environment, resulting in the exfiltration of high-value PII and PHI over a two-week period.
