In a concerning development in the cybersecurity landscape, Consulting Radiologists, a healthcare provider based in Minnesota, has issued a notification to nearly 512,000 patients following a cyberattack in February. The company, which offers radiology services to 22 hospitals and clinics and provides remote teleradiology across the upper Midwest, detected suspicious activity in its network on February 12. Investigations revealed that an unauthorized party had accessed a significant volume of sensitive patient information.

The breach exposed patients’ names, addresses, dates of birth, Social Security numbers, health insurance details, and medical records. Although there is currently no evidence that this data has been misused, Consulting Radiologists has taken the precaution of informing affected individuals and offering them a year of free credit monitoring services.

Inside the Breach

This incident comes amid claims by two ransomware gangs, LockBit and Qilin, that they were behind the data theft. Notably, the latter, a Russia-based group, boasted of stealing over 70GB of data, which included more than 94,667 files. Qilin is also implicated in the Synnovis ransomware attack, which has severely impacted healthcare operations in London, demonstrating a disturbing trend of targeted attacks on critical healthcare infrastructure.

Safeguarding Against Future Cyber Threats

In response to the breach, Consulting Radiologists has enlisted a cybersecurity firm to bolster its network security, introducing additional monitoring tools and enhancing system protections to prevent future incidents. However, details about how the attackers penetrated the network or whether a ransom was demanded have not been disclosed.

This event underscores the growing threat of cyberattacks in the healthcare sector, highlighting the critical need for robust cybersecurity measures to protect sensitive patient data and ensure the continuity of medical services.
