Health-ISAC helps protect the global health sector through botnet disruption

On April 6, 2022, Microsoft, Health-ISAC and FS-ISAC filed a civil suit in the US Federal Court in Atlanta against operators of the Zloader botnet.

Zloader is responsible for delivering Ryuk ransomware (among other malware) which has been linked to more than 200 ransomware attacks impacting hospitals, public health departments, nursing homes and patient care facilities around the world since 2018.  In many cases, the ransomware attacks knocked hospital IT systems off-line resulting in cancelled surgeries and delayed medical care.

The Court approved our request for a restraining order that allowed Microsoft to seize the botnet infrastructure, including hundreds of domains used by the criminal organization.  The efforts showed an immediate impact with nearly 50,000 infected computers no longer able to take commands from the Zloader bot controllers.  That number should continue to increase and hope possibly put an end to Zloader’s ability to distribute malware forever.

Health-ISAC plans to continue botnet disruption projects like this in the future to help protect the global health sector.  If you’re interested in participating, please email
