A cybersecurity research firm has detected a significant trove of data circulating on the dark web, reportedly containing $1.24$ million files associated with Doctor Alliance, a health IT platform specializing in automated billing services. Many of these files are directly related to patient care. This finding was confirmed in a report released on Monday by Cybernews, which verified a post on a popular hacker forum. This post, likely made by the individuals responsible for the breach, claims that a total of $353$ gigabytes of data was exfiltrated from Doctor Alliance’s network infrastructure.
The stolen data has not yet been publicly released. The user, identified by the alias “GOD,” has set a deadline of November 21, 2025, threatening to either publish or sell the information unless a ransom of $\$200,000$ is paid. As proof of their claim, the alias “GOD,” who may represent a group, made a small $200$ MB sample of the files available. Upon reviewing this sample, Cybernews determined that the exposed files contain “various medical records, riddled with sensitive personal data,” including specific details such as patient prescriptions, treatment plans, names, health insurance numbers, phone numbers, home addresses, and hospital orders.
The access to and potential leakage of this type of information would constitute a mandatory reportable incident under the Health Insurance Portability and Accountability Act (HIPAA). Cybersecurity researchers analyzing the data believe that if the trove is verified as legitimate, it presents an extreme risk to both patients and employees. The comprehensive nature of the stolen records makes them highly valuable for identity theft, blackmail, or other criminal activities. Specifically, this threat includes both medical identity theft and various forms of insurance fraud using the victims’ data.
Researchers stated in their report that the “data leak poses a huge risk of identity theft and medical fraud for the patients involved, such as obtaining medical services or prescription drugs in the victim’s name.” They also warned that this situation could expose both doctors and patients to further social engineering attacks based on the leaked personal information. The alleged cybercriminals have publicly promised that the entire dataset will be permanently deleted should the ransom demand be met.
Details regarding the actual attack, such as the exact date it occurred or the vector used to compromise the network, were not disclosed in the forum post, which first appeared on November 10. No well-known hacking group has taken public responsibility for the intrusion; the forum user responsible for the post has a relatively short history on the platform, dating back only four months.
