Transcription Service Leaked Medical Records

MEDantex, a Kansas-based company that provides medical transcription services for hospitals, clinics and private physicians, took down its customer Web portal last week after being notified by KrebsOnSecurity that it was leaking sensitive patient medical records — apparently for thousands of physicians.

On Friday, KrebsOnSecurity learned that the portion of MEDantex’s site which was supposed to be a password-protected portal physicians could use to upload audio-recorded notes about their patients was instead completely open to the Internet.

What’s more, numerous online tools intended for use by MEDantex employees were exposed to anyone with a Web browser, including pages that allowed visitors to add or delete users, and to search for patient records by physician or patient name. No authentication was required to access any of these pages.

This exposed administrative page from MEDantex’s site granted anyone complete access to physician files, as well as the ability to add and delete authorized users.

Several MEDantex portal pages left exposed to the Web suggest that the company recently was the victim of WhiteRose, a strain of ransomware that encrypts a victim’s files unless and until a ransom demand is paid — usually in the form of some virtual currency such as bitcoin.

Contacted by KrebsOnSecurity, MEDantex founder and chief executive Sreeram Pydah confirmed that the Wichita, Kansas based transcription firm recently rebuilt its online servers after suffering a ransomware infestation. Pydah said the MEDantex portal was taken down for nearly two weeks, and that it appears the glitch exposing patient records to the Web was somehow incorporated into that rebuild.

“There was some ransomware injection [into the site], and we rebuilt it,” Pydah said, just minutes before disabling the portal (which remains down as of this publication). “I don’t know how they left the documents in the open like that. We’re going to take the site down and try to figure out how this happened.”

It’s unclear exactly how many patient records were left exposed on MEDantex’s site. But one of the main exposed directories was named “/documents/userdoc,” and it included more than 2,300 physicians listed alphabetically by first initial and last name. Drilling down into each of these directories revealed a varying number of patient records — displayed and downloadable as Microsoft Word documents and/or raw audio files.

Although many of the exposed documents appear to be quite recent, some of the records dated as far back as 2007. It’s also unclear how long the data was accessible, but this Google cache of the MEDantex physician portal seems to indicate it was wide open on April 10, 2018.

Among the clients listed on MEDantex’s site include New York University Medical Center; San Francisco Multi-Specialty Medical Group; Jackson Hospital in Montgomery Ala.; Allen County Hospital in Iola, Kan; Green Clinic Surgical Hospital in Ruston, La.; Trillium Specialty Hospital in Mesa and Sun City, Ariz.; Cooper University Hospital in Camden, N.J.; Sunrise Medical Group in Miami; the Wichita Clinic in Wichita, Kan.; the Kansas Spine Center; the Kansas Orthopedic Center; and Foundation Surgical Hospitals nationwide. MEDantex’s site states these are just some of the healthcare organizations partnering with the company for transcription services. Continue reading →
