On July 21, 2021, Austin Cancer Centers experienced a ransomware attack that disrupted its information technology systems. The attack forced a two‑week shutdown of electronic systems while staff continued to provide patient care through manual processes. During the incident, personal and medical data belonging to over 36,000 patients were compromised. The exposed information included names, social security numbers, diagnoses, insurance details, and laboratory results. A limited number of patients also had mailed credit card information exposed as part of the breach. Following the attack, the organization offered mitigation services through Equifax to affected individuals. No evidence of data misuse was identified in the aftermath of the incident. The intrusion reportedly leveraged sophisticated evasion techniques during system access. The organization worked to restore operations while maintaining manual patient care throughout the outage.
