Description

On October 28, 2020, Proton Therapy Center, LLC (PCPT) in Knoxville and MTPC, LLC (MTPC) in Nashville experienced an information technology security incident during early morning hours. Both facilities, which provide cancer treatment through proton radiation therapy and were financed through municipal bonds, immediately initiated response protocols following the breach. The incident caused operational disruptions affecting clinical and financial systems, though the centers maintained patient care delivery through established contingency measures. By December 2, 2020, the organizations disclosed these disruptions in a bond filing, characterizing them as temporary but ongoing. Neither entity specified the attack vector or duration of system compromise in public reports.

The centers implemented extensive IT security protocols and collaborated with external security partners to restore operations, prioritizing system recovery while maintaining offline documentation methods as temporary workarounds. Clinical operations continued without interruption to patient treatments, with no evidence suggesting compromised safety standards during the incident response period. Financial operations experienced more significant disruptions, though the filing did not detail specific impacted processes. Investigations found no evidence that patient or employee data was accessed, copied, or misused. Both facilities maintained their backup processes throughout the recovery period, which extended beyond the initial disclosure date. The bond filing served as the primary public notification mechanism regarding the incident's operational impacts.
