In defending Apple's stance against the FBI last year, Apple Senior VP Craig Federighi penned an op-ed for the Washington Post saying that the government's request for a backdoor into iPhones. The words sound pretty wise in the wake of the massive ransomware attack which made use of an NSA-held vulnerability.

Federighi even speculated that the scope of an attack would go beyond the type of credit card and identity theft that was becoming commonplace.

OK, in this case it was PCs, not phones, that were the vulnerable point for the attack. But his point is (or at least should be) well taken. And I would expect Apple to continue building strong security into its products and defending the approach.
