What We Know So Far About a Possible Mission Community Hospital Breach
News of the Mission Community Hospital data breach is still fresh; however, what we know at this point comes from several news reports covering the potential breach. According to this source, on May 31, 2023, databreaches.net reported that RansomHouse, a well-known ransomware group, claimed responsibility for an attack on Mission Community Hospital. The group also provided several files, which serve as proof that the attack occurred.
Subsequently, on June 1, 2023, counsel for Mission Community Hospital released a letter confirming the cyberattack. Evidently, Mission first learned of the issue when it was investigating a network switch failure on May 1, 2023. As the hospital investigated the failure, it found evidence of a compromise. Mission’s continued investigation determined the ransomware group accessed the hospital IT network through vulnerabilities existing in both the network and the VMware environments.
Mission appears to be in the process of finalizing its investigation. Thus, the hospital has not yet released which data types may have been impacted. Once Mission Community Hospital confirms that patient data was compromised, it will send out data breach letters to all individuals whose information was compromised as a result of the recent data security incident.
