(full disclosure, I used to work at HQ in Cupertino) … it’s not generally Apple’s M.O. to respond to things like this with, at most, “we received your message”.

Apple’s infosec team is almost certainly looking into this, assuming the report made it’s way to them. I’ll reach out to some of my contacts there n’ make sure they’re at least aware of the exploit.

Given how guarded Apple is about revealing anything, I wouldn’t expect much of a response though, even from a friend.
