As far as we know, this is not possibly. This is some day zero hack if it were true. Meaning they’ve found a flaw in iOS security. This would be so huge that Apple will likely pay a good bounty for it.

Now with that said, are you a millionaire? How much can they get from you if they drained all of your accounts and max your credit? If the answer is less than $100k, then it likely isn’t what you think it is.

No hacker would spend the amount of resources to break iOS security and then hack a nobody with so less money. As soon as he uses that hack, it’s out there for Apple to patch. It won’t be worth it to use such a valuable hack on a few hundred dollars, or even a few thousand dollars. A hack like what you described would make news within hours.

Jailbreakers spend months to years to develop a single hack for iOS. Are you “big” enough for them to waste a hack on you? Likely not.

You were likely compromised somewhere else. Probably your computer or through a data leak with your email and password.
