A data breach affecting more than 171,000 individuals was recently disclosed by Doctors Imaging Group, a Florida radiology practice. The company’s investigation revealed that hackers had access to its network for nearly a week, from November 5 to November 11, 2024, and managed to exfiltrate a significant number of files. It took the organization almost a year to fully determine the scope of the breach and identify the affected individuals. The prolonged investigation period highlights the complexity and resources required to accurately assess the impact of such cyberattacks.
Following the completion of its investigation in late August 2025, Doctors Imaging Group formally notified the U.S. Department of Health and Human Services (HHS) about the incident. The report confirmed that the personal and medical data of over 171,000 people had been compromised. This disclosure is a mandatory step for healthcare organizations under federal regulations, ensuring transparency and providing a record of significant security incidents. The sheer number of affected individuals underscores the vulnerability of healthcare systems to large-scale data breaches, making them a prime target for cybercriminals.
The stolen information is highly sensitive and includes a wide range of personal and medical details. According to the company’s breach notice, the hackers obtained names, addresses, dates of birth, Social Security numbers, financial account numbers, and various medical identifiers such as patient account and medical record numbers. Health insurance information, medical treatment details, and medical claim information were also part of the compromised data. This comprehensive list of exposed data makes the affected individuals particularly susceptible to identity theft, financial fraud, and other malicious activities.
While the attack’s motives are not fully clear, there’s no public indication that a known ransomware group was responsible. Unlike many cyberattacks where the perpetrators quickly claim responsibility, no known cybercrime gang has taken credit for the breach at Doctors Imaging Group. This lack of attribution could mean the attackers were a less-known group or that they simply chose not to publicize their actions. The absence of a public claim further complicates the understanding of the attack’s nature and the ultimate fate of the stolen data.
In the broader context of healthcare cybersecurity, a data breach of this size, while alarming, isn’t unique. The healthcare sector is a frequent target due to the wealth of sensitive information it holds. The high volume of patient data often means that a single successful breach can affect hundreds of thousands, or even millions, of people. This incident serves as a stark reminder of the continuous threats facing healthcare providers and the critical need for robust cybersecurity measures to protect patient information.
