Cyberattack on Mission Community Hospital

CRITICAL-56
MIS144625623
Mission Community Hospital in California continues to investigate a cyberattack.
The RansomHouse advertisement for Mission Community Hospital stated that it had 2.5 TB of data and included some supporting documentation.
Following further analysis, they came to the conclusion that the threat actor had exploited vulnerabilities in both the network and VMware environments to get access to the hospital infrastructure and have an impact on vital systems.
They list a number of folders that contain both current files and files from previous years that contain patient data as part of their leak.

Ransomware Attack on Mission Community Hospital

CRITICAL-101
MIS2394623
California's Mission Community Hospital said that they may have been the target of a ransomware assault that exposed their personal data.
Threat actors from RansomHouse took ownership of the attack and proved it with a number of data. Apparently, they downloaded 2.5 TB of data.
RansomHouse appears to have accessed the imaging system and picture files, along with employee-related files and some financial reports and files, according to the evidence files.
The earlier backup files were the only patient references in the proof files. It is unclear if they were able to access the EMR system or any recent patient data.
