Ransomware attack on Ohio hospital affects nearly 8,000 patients
by Kapua Iao
Muskingum Valley Health Centers (MVHC) sent a letter to affected patients on July 31 to inform them of a ransomware attack on the electronic medical record (EMR) system of OB/GYN Specialists of Southeastern Ohio Inc.
Before sending this notice, MVHC took the server containing the EMR system offline and began an internal investigation. It also hired an external cybersecurity firm.
Who was affected by the ransomware attack?
According to the cybersecurity firm MVHC hired, a ransomware attack May 31 “encrypted three systems of OB/GYN Specialists, including the server containing patient records for the period of 2012-2017.”
Subsequently, an employee discovered the ransomware on June 2.
Exposed protected health information (PHI) may include demographic, clinical, and financial information such as:
|Demographic information||Clinical Information||Financial Information|
|Patient names||Diagnoses/conditions||Claims information|
|Date of birth||Lab results|
|Other treatment information|
RELATED: Is a Name PHI?
Unfortunately, MVHC also assumes the breach exposed social security numbers but not bank/credit card account information.
As reported to the U.S. Department of Health & Human Services Office for Civil Rights (OCR), the breach affected 7,447 individuals.
What steps were taken by MVHC after the breach?
MVHC explains in its notice that there is “no evidence that the data was exfiltrated (copied or transferred).”
In other words, the hospital believes there is no opportunity for the threat actor to use or publicly disclose PHI.
Nevertheless, MVHC offered all affected individuals identity theft protection services along with recommended steps to follow.
And given that a threat actor did breach its system, MVHC:
- Revised its security policies and procedures
- Strengthened password requirements
- Updated its security risk analysis
There is no mention of updated employee awareness training.
How harmful is ransomware?
RELATED: The Costs of Ransomware Attacks
MVHC confirms that three of its systems were encrypted, but they did not confirm if there was a ransom demand or how the ransomware first got onto the servers.
Ransomware is harmful to any business/organization, and according to the Verizon 2020 Data Breach Investigations Report, it is on the rise.
Specifically for healthcare organizations, INTERPOL’s Secretary General Jürgen Stock states that locking a hospital’s system could lead to delayed care.
Moreover, a recent study in the Journal of General Internal Medicine found that patients withheld information to avoid PHI exposure.
OCR lists over 1.13 million individuals affected by cyberattacks in July 2020, with the majority coming from hacking/IT incidents. While not the biggest healthcare breach in July, MVHC’s still demonstrates the need for solid cybersecurity.
How can strong email security help?
