One could also argue, that as Apple is commonly branded as "secure" alternative, and therefore high profile targets are potentially using their products. This might mean that interest is much higher for attackers on that side. They might not care so much about Android. Increased interest and effort means that more likely something is found. Also, Apple's sandboxing settings and permission managing makes the most malware pretty useless with App store policies (no sideloading), so only RCE exploits are kinda useful. What it comes to iMessages, that is the most interesting channel with Safari to deliver exploits, iMessage without user interaction and Safari with some. All you need to know is that target is using iPhone. Other non-default applications as target introduces new challenges. iMessage and Safaring being part of OS updates might indicate, that they are handled differently compared to other apps - is security policy same, worse or better? Is there larger attack interface to system by using these apps?
