Numbers from the OS, Inc. breach dribble in…

Posted on May 13, 2019 by Dissent

OS, Inc. provides revenue management (billing) services to covered entities. I recently reported on a phishing-related breach they experienced in 2018 that was first disclosed this month. As I noted in that post, their notification specifically mentioned a number of their affected clients. Their disclosure did not, however, provide a total number of patients affected, nor name clients who probably wanted to make the disclosure to their patients themselves.

So here’s what we know so far, and there’s likely a lot more to come:

  • Spectrum Health Lakeland: they disclosed the breach to 1,100 St. Joseph’s patients
  • Tahoe Forest Health District – mentioned in OS’s notice, but no release or numbers from them yet.
  • Sparta Community Hospital – mentioned in OS’s notice, but no release or numbers from them yet.
  • Sauk Prairie Healthcare, Inc. – mentioned in OS’s notice, but no release or numbers from them yet.
  • Idaho Department of Health and Welfare – mentioned in OS’ notice. A media report reveals that  2,060 were notified.
  • Fort Healthcare in Wisconsin – mentioned in OS’s notice. A media report reveals that they are  reportedly notifying 19,000 patients.
  • Midwest Medical Center – not mentioned in OS’s notice, but media reports that they are notifying 8,000 patients.

I’ll try to update this post as I find more details. Feel free to let me know of any updates if you find them.
