An Italian teen who we will call talented but irresponsible found and developed an exploit of Apple’s Mac OS. Talented in that he could find not just one but two in the relatively secure Mac OS. Irresponsible in that he published the details on GitHub only hours after notifying the software giant of his discovery. It is customary to allow the developer time to address and patch an issue before disclosing it to the world for every hacker to jump on and exploit. What he did by discovering the flaws is commendable. But by disclosing them without any adequate time for the developer (Apple) to respond is reckless and causes a large issue opening even more computers to hack attempts because of his rush to seek fame.
The exploit he developed yields root access
