Apple was not aware of the attack until researchers found evidence of it on a Saudi activist's phone.
Many of the vulnerabilities relied on using iMessage to own the rest of the phone, Google's Project Zero said.
Companies that buy and sell exploits, or zero-days, are now willing to offer seven figures for hacks that allow spies and cops to steal WhatsApp, iMessage and other chat app messages.
Apple wants to make its cloud as secure and private as its devices, starting with iMessage.
From roadmen to businessmen, the BlackBerry served one and all!
Researchers write that iMessage’s encryption “does not conform to best cryptographic practices and generally seems ad hoc.”
The attack could have implications for other apps too.
