Report: Significant Security Risks With Healthcare And Financial Services Mobile Apps

Arxan Technologies logo Arxan Technologies recently released its fifth annual report about the state of application security. This latest report also highlighted some differences between how information technology (I.T.) professionals and consumers view the security of healthcare and financial services mobile apps. Overall, Arxan found critical vulnerabilities:

"84 percent of the US FDA-approved apps tested did not adequately address at least two of the Open Web Application Security Project (OWASP) Mobile Top 10 Risks. Similarly, 80 percent of the apps tested that were formerly approved by the UK National Health Service (NHS) did not adequately address at least two of the OWASP Mobile Top 10 Risks... 95 percent of the FDA-approved apps, and 100 percent of the apps formerly approved by the NHS, lacked binary protection, which could result in privacy violations, theft of personal health information, and tampering... 100 percent of the mobile finance apps tested, which are commonly used for mobile banking and for electronic payments, were shown to be susceptible to code tampering and reverse-engineering..."

Some background about the U.S. Food and Drug Administration (FDA). The FDA revised its guidelines for mobile medical apps in September, 2015. The top of that document clearly stated, "Contains Nonbinding Regulations." The document also explained which apps the FDA regulates (link added):

"Many mobile apps are not medical devices (meaning such mobile apps do not meet the definition of a device under section 201(h) of the Federal Food, Drug, and Cosmetic Act (FD&C Act)), and FDA does not regulate them. Some mobile apps may meet the definition of a medical device but because they pose a lower risk to the public, FDA intends to exercise enforcement discretion over these devices (meaning it will not enforce requirements under the FD&C Act). The majority of mobile apps on the market at this time fit into these two categories. Consistent with the FDA’s existing oversight approach that considers functionality rather than platform, the FDA intends to apply its regulatory oversight to only those mobile apps that are medical devices and whose functionality could pose a risk to a patient’s safety if the mobile app were to not function as intended. This subset of mobile apps the FDA refers to as mobile medical apps."

The Arxan report found that consumers are concerned about app mobile security:

80 percent of mobile app users would change providers if they knew the apps they were using were not secure. 82 percent would change providers if they knew alternative apps offered by similar service providers were more secure."

Arxan commissioned a a third party which surveyed 1,083 persons in the United States, United Kingdom, Germany, and Japan during November, 2015. 268 survey participants were I.T. professionals and 815 participants were consumers. Also, Arxan hired Mi3 to test mobile apps during October and November, 2015. Those tests included 126 health and financial mobile apps covering both the Apple iOS and Android platforms, 19 mobile health apps approved by the FDA, and 15 mobile health apps approved3 by the UK NHS.

One difference in app security perceptions between the two groups: 82 percent of I.T. professionals believe "everything is being done to protect my apps" while only 57 percent of consumers hold that belief. To maintain privacy and protect sensitive personal information, Arxan advises consumers to:

  1. Buy apps only from reputable app stores,
  2. Don't "jail break" your mobile devices, and
  3. Demand that app developers disclose upfront the security methods and features in their apps.
