More than 45 million medical images – including X-rays and CT scans – are left exposed on unprotected servers, a CybelAngel report reveals.
The analysts discovered millions of sensitive images, including personal healthcare information (PHI), were available unencrypted and without password protection.
No need for a username or password
The analysts found that openly available medical images, including up to 200 lines of metadata per record which included PII (personally identifiable information; name, birth date, address, etc.) and PHI (height, weight, diagnosis, etc.), could be accessed without the need for a username or password. In some instances login portals accepted blank usernames and passwords.
“The fact that we did not use any hacking tools throughout our research highlights the ease with which we were able to discover and access these files,” says David Sygula, Senior Cybersecurity Analyst at CybelAngel.
“This is a concerning discovery and proves that more stringent security processes must be put in place to protect how sensitive medical data is shared and stored by healthcare professionals. A balance between security and accessibility is imperative to prevent leaks from becoming a major data breach.”
Todd Carroll, CybelAngel CISO further commented, “Medical centers work with a vast, interconnected web of third-party providers and the cloud is an essential platform for sharing and storing data. However, gaps in security, such as this, present a huge risk, both for the individuals whose data is compromised and the healthcare institutions that are governed by regulations to protect patients’ data.
“The health sector has faced unprecedented challenges this year, however the security and privacy of their patients’ most personal records must be protected, to prevent highly confidential data falling into the wrong hands.”
Security risks of publicly accessible images
The report highlights the security risks of publicly accessible images containing highly personal information including ransomware and blackmail. Fraud is a particular risk, as this type of imagery fetches a premium on the dark web.
Simple steps that healthcare facilities can take to safeguard the way they share and store data including to:
- Determine if pandemic response exceeds your security policies: Ad hoc NAS devices, file-sharing apps and contractors may take data beyond your ability to enforce access controls.
- Ensure proper network segmentation of connected medical imaging equipment: Minimize any exposure critical diagnostic equipment and supporting systems have to wider business or public networks.
- Conduct real-world audit of third-party partners: Assess which parties may be unmanaged or not in compliance with required policies and protocols.
