Apple was less virus/malware attacked than Microsoft for so long that the dirtbags who do that sort of thing decided to “make it fair”.
Hackers of that kind are worthy of summary execution!
Of course, that’s just MY opinion...
In other words, to get infected with this trojan, the iPhone user must first Jailbreak his iPhone, violating his guarantee and user agreement, have that specific non-Apple application loaded on the iPhone, download a "prep application" from a site totally unrelated to the application the Trojan says its intended for, install it into the jailbroken iPhone to get infected. Then, and only then, can they complain... and then sue Apple...
How stupid can a user be?
Now, does anyone want to say that Macs are only secure because so few people use them that no one will write malware for it... security by obscurity... You can't get much more obscure than the case of the iPhone trojan above... yet, someone has written malware for it...
