Unfortunate that this researcher, shame on apple for not handling these vulnerabilities quickly.
I used to believe that iphones were more secure than android and was considering making the switch. After reading this article and with some other recent news (CSAM[1], spam on the app store[2]) I don't think I'll be hopping on the iOS train anytime soon.
