A cyberattack has left hospitals in chaos across 5 states as health administrators and authorities scramble to get emergency services running again. Many primary doctor offices remain closed and elective procedures have been postponed.

From the AP:

The "data security incident" began Thursday at facilities operated by Prospect Medical Holdings, which is based in California and has hospitals and clinics there and in Texas, Connecticut, Rhode Island and Pennsylvania.

"Upon learning of this, we took our systems offline to protect them and launched an investigation with the help of third-party cybersecurity specialists," the company said in a statement Friday. "While our investigation continues, we are focused on addressing the pressing needs of our patients as we work diligently to return to normal operations as quickly as possible."

Most emergency rooms reopened Thursday night, according to the AP, but ambulances were reportedly rerouted to other hospitals during the outage. It is unknown what effect that had on patients in critical condition.

Those who have appointments postponed have been notified individually by the hospitals.

The FBI (and presumably other federal agencies) are reportedly on the case.

The FBI in Connecticut issued a statement saying it is working with "law enforcement partners and the victim entities" but could not comment further on an ongoing investigation.

Not sure that makes me feel better...
