Cybersecurity Threat Advisory 0021-20: Healthcare Facilities Targeted During COVID-19 Outbreak

Advisory Overview

One of the Czech Republic’s biggest hospitals has been hit with a cyber-attack amid COVID-19 testing. Healthcare facilities, especially hospitals are advised to be on high alert. SKOUT recommends all organizations to be extra cautious during this time of crisis and understand that cyber attacks are likely to be on the rise.

Technical detail and additional information

What is the threat?

Brno University Hospital, the second largest hospital in the Czech Republic has been hit with a cyber-attack while dealing with COVID-19 outbreak. While the technical details of the breach have not been released, hospital officials have stated that staff were forced to shut down the entire IT network during the incident. The security breach has forced Brno hospital to cancel all surgical procedures and re-route patients to nearby hospitals. The U.S. Health and Human Services Department also reported an unsuccessful attack on their network.

Why is this noteworthy?

Brno Hospital is one of the Czech Republic’s largest hospitals and has been conducting testing  for the coronavirus where there has been 117 infections confirmed. As per the hospital’s director, “gradually, the individual systems were falling, so all computers had to be shut down, We are able to investigate patients, but we are not yet able to store data. Patient care is maintained, and we are working to be able to store data for hours.”

Although the target was a hospital in this instance, all organizations are susceptible at a time with significant changes to your systems allowing remote workers combined with high emotions.

What is the exposure or risk?

While Healthcare workers and administrative staff are working diligently during this time of crisis, attackers are using this as an opportunity to exploit staff via phishing and malware attacks related to COVID-19. The campaigns vary in exact messaging, but many have impersonated the Government organizations, The World Health Organization or HR departments issuing warning.
