Yeah mate i think it’s fairly likely that many of us on here don’t go around installing bullshit apps. I haven’t been affected either.
The previous hack (manage my health) was not an app that people installed on their phones, it was a health management portal that patients were signed up to when they enrolled to clinics and practices that made use of that platform. These health providers used this as a database to store the medical information for all their patients. Molemaps, xrays, doctors notes, everything was uploaded, not by patients, but by their medical care providers.
If you’re enrolled at a gp it’s likely that your data is sitting in a similar system. MyIndici is an example I’m aware of, although it hasn’t been hacked to my knowledge.
The concern doesn’t stop with health apps either. Any third party data portal/platform is theoretically at risk, and kiwi companies love outsourcing risk to these private corps. Imagine the fallout from a RealMe hack, for example? It’s no less likely at this point, and because of the lackluster regulation around these data platforms, they have no real incentive to beef up security. That’s the issue here.
