San Gorgonio Memorial Hospital suffered a malware attack that caused it to shut down its electronic health records for about 6 days. Archive patient information including names and addresses stored on servers was breached during the hack. The hospital's online systems were immediately shut down to protect data and hospital employees temporarily reverted to paper recordkeeping. The attack caused delays in test results and some other healthcare services were inevitable which caused the patients to visit back 1-2 times a day.

The California Office of the Attorney General reported that San Gorgonio Memorial Hospital experienced a data breach involving unauthorized access to patient information between October 29, 2022, and November 10, 2022. The breach was reported on December 7, 2022, and affected information may include names, addresses, dates of birth, medical record numbers, visit ID numbers, health insurance information, and clinical information. No government-issued identification numbers or financial account information has been identified as compromised.
