At Least 750 US Hospitals Faced Disruptions During Last Year’s CrowdStrike Outage, Study Finds
Of those, more than 200 appear to have had outages of services related to patient care following CrowdStrike’s disastrous crash, researchers have revealed.
When, one year ago today, a buggy update to software sold by the cybersecurity firm CrowdStrike took down millions of computers around the world and sent them into a death spiral of repeated reboots, the global cost of all those crashed machines was equivalent to one of the worst cyberattacks in history. “We are unaware of any other hypothesis that would explain such simultaneous geographically-distributed service outages inside hospital networks such as we see here” other than CrowdStrike’s crash, writes UCSD computer science professor Stefan Savage, one of the paper’s co-authors, in an email to WIRED. “The duration of the downtimes is different, but the breadth, the number of hospitals affected across the entire country, the scale, the potential intensity of the disruption is similar,” says Jeffrey Tully, a pediatrician, anesthesiologist, and cybersecurity researcher who coauthored the study.
