What Happened at CareSTL Health?

CareSTL Health, a prominent community health center serving the St. Louis region, may have been targeted by the Kawa4096 threat actor, who has claimed that they have lifted 150GB of personal data from the CareSTL database. CareSTL Health provides critical services, including primary care, dental, and behavioral health support, to thousands of underserved individuals.

The KAWA4096 ransomware group is a newly identified cybercriminal entity, marking its presence in the evolving landscape of ransomware threats. KAWA4096 has claimed at least 11 victims, with a primary focus on organizations in the United States and Japan, though some attacks remain undisclosed on its dark web leak site. The group employs double extortion tactics—encrypting data and threatening to leak it—demanding payment. While its origins remain murky, its aggressive approach signals a serious IT security threat.

This alleged cyberattack reportedly compromised electronic medical records, patient contact details, and possibly financial information, though the full extent remains under investigation. Such unfortunate incidents are not uncommon in the healthcare industry—2024 saw over 182 million records breached.

Exposed personal health records—such as names, Social Security numbers, and medical insurance data—can lead to identity theft, medical fraud, or financial exploitation. Victims should consider legal action if negligence or HIPAA violations are suspected.

Class Action lawsuits can hold any entity negligent accountable, pushing for improved security practices to prevent future breaches. Contact our legal team to learn more about this incident and to begin filing a data breach claim.
