Hendrick Medical Center sent out the following press release Monday afternoon:

Over the weekend, our information technology department became aware of a network security threat at Hendrick Medical Center (main campus) and some Hendrick clinics. To fully address the issue, we have shut down Hendrick IT networks. Our primary goal is to maintain patient safety while administering downtime procedures.

At this time, Hendrick Medical Center Brownwood and Hendrick Medical Center South are not impacted by the issue.

Be confident that we have been working around the clock to assess and resolve the issue. Like many other healthcare organizations, network security threats are an unfortunate reality in our industry and we have coordinated with industry experts and law enforcement to address the issue to get our networks back up and running.
