Universal Health Services said Thursday that computers and systems at all of its 250 U.S. healthcare facilities were shut down by a malware attack over the week. The healthcare provider said that it expects to get networks restored and reconnected "soon." It stressed that electronic medical record systems were not directly impacted by the attack.
- As Inside Security reported, UHS had to redirect ambulances and move patients requiring surgery to different hospitals as a result of the attack.
- Based on descriptions that UHS employees posted on social media and related to media outlets, it appears that the attack was carried out by the Ryuk ransomware group.
- UHS operates more than 400 healthcare facilities in the U.S. and U.K, has more than 90,000 employees, and serves 3.5 million patients per year.
