Lurie Children's Hospital of Chicago: Ransomware Attack Timeline

Written by Aditi Uberoi | 25 April 2024

A ransomware attack in the healthcare space is always an ominous reminder of how cyber crime can directly impact human life. In case of the recent cyber attack on Lurie Children's Hospital of Chicago, not only was sensitive personal data stolen and allegedly sold online. The cybersecurity incident also impacted the speed at which emergency care services could be provided to children. We've captured everything that went down in this chilling illustration of how cyber crime can be debilitating to human life itself in our Lurie Children's Hospital Ransomware Attack Timeline. 

Topics covered in the Lurie Children's Hospital Ransomware Attack Timeline: 

1. The Incident
2. The Impact on the Hospital & Patients
3. Actions Taken by Lurie Children's Hospital

At Cyber Management Alliance, we regularly create educational Cyber Attack Timelines. The purpose is simply to present cyber attacks in a chronological and easy-to-understand format. We break down everything that took place during the cybersecurity incident into bite-sized points that help you make sense of how cyber crime usually unfolds. 

The primary objective behind this exercise is to raise cybersecurity awareness. It is also to offer a retrospective view of recent attacks so you can learn from them and improve your own cyber defences. These reader-friendly attack timelines will show you the tactics and techniques of the cyber criminal. It will also simplify the process of understanding the impact a particular attack had and how the victim responded. 

In many cases, you can take a cue from others' cyber incident response plans and processes. In other instances, you may identify some gaps which you can then proceed to plug in your own cyber incident response strategy. Cyber attacks from your specific industry can be really useful as inspiration to create Cyber Security Tabletop Exercise Scenarios for your organisation. 

A Cyber Attack Tabletop Exercise is a vital tool in your overall cybersecurity incident response arsenal. It puts your team in a simulated attack situation and evokes the kind of responses they would exhibit during a real cyber event. It helps them build muscle memory and rehearse cybersecurity decision-making. Having a highly relevant, specifically-created scenario is key to a successful cyber drill and that's where studying the attack timelines can really benefit.     

The Incident - Lurie Children's Hospital of Chicago

  • February 01, 2024: Bleeping Computer reported that Lurie Children's Hospital in Chicago was forced to take IT systems offline after a cyber attack, disrupting normal operations and delaying medical care in some instances.

  • February 27, 2024: The Recorded Future News said in its report the Rhysida ransomware-as-a-service group that disrupted 16 hospitals across the U.S. — listed Lurie on its darknet extortion site and this ransomware group attempted to sell data stolen from the institution for 60 bitcoins, equivalent to just over $3.4 million. 
  • March 12, 2024: According to NBC 5 Investigates, Lurie Children’s Hospital said it investigated claims that information reportedly stolen during a recent cyber attack against the hospital was sold online. On March 08, 2024, according to a post obtained by NBC 5 Investigates, the ransomware-for-hire group Rhysida claimed it had sold data obtained from Lurie Children's Hospital. The post, which was authenticated by the cyber security firm Check Point Software, said: “All data was sold”. 
  • March 12, 2024: In a statement provided to NBC 5 Investigates, a hospital spokeswoman said: “We are aware that individuals claiming to be Rhysida, a known threat actor, claim to have sold data they allege was taken from Lurie Children’s.

The Impact on the Hospital & Patients

  • February 01, 2024: According to Bleeping Computer, the hospital announced on its website and social media platforms that it is actively responding to a cybersecurity incident, which unfortunately resulted in network systems being taken offline to prevent the attack's spread. 
  • February 01, 2024: As per Bleeping Computer’s report, the healthcare provider stated that the incident impacted the hospital's internet, email, phone services, and ability to access the MyChat platform. Those suffering from a healthcare emergency were advised to dial 911 or visit their nearest emergency department.

Iriel Thomas, parent of a 10-year-old patient who was admitted to the hospital on January 27, 2024, said the outage caused their son’s treatment procedure to be delayed. Thomas was apparently told the outage had no impact on emergency services as the hospital continued to alert families about the outage and ask for their patience through messages on its website and social media. 
  • February 01, 2024: As per ABC7Chicago’s report, Iriel Thomas said: "Everyone thought it was going to come back quickly and no, so it made everybody go back to paper charts, writing everything down, because computers are down at this point. It's just first come, first served on what is important right now". 
  • February 01, 2024: As per ABC7Chicago covered one more patient’s statement as their daughter had to go through a treatment. Kelly Beeman and her wife were unaware of the outage when they arrived at Lurie for an appointment for their 18-month-old daughter. She said they were hoping to review ultrasound results with their doctor but couldn't. However, they were able to get a prescription the old school way.

  • February 01, 2024: Kelly Beeman said: "You can hear everybody talking about it, there are doctors huddled in the corner, this is what we are going to do, it seems like they are handling the situation. I haven't done it in this way in a long time on paper, but we got what we needed".
