This Kerala youth cracks Apple's security lock feature

Hemanth Joseph, an engineering student from Kerala, has found out a way to crack open Apple's highly secure activation lock, that allows the owner to prevent others from using their iPhone or iPad once it's lost or stolen.
"I found out a way to bypass the lock screen when somebody tries to open any of devices, locked by the owner using 'Find iPhone' app," said Joseph, a final-year mechanical engineering student at Amal Jyothi College of Engineering, Kanjirappally.
Hemanth had purchased a used iPad from eBay, an etailer, for his friend. Locked by the previous owner all efforts to unlock it failed.
After being prompted by his friends to reveal how he did it, Joseph wrote in his blog that he used the security lapse in the input fields for name, username and password. Since, there was no character limit in those input fields, it got easier for him to bypass the security lock. Furthermore, he said that no one would set a Wi-Fi name with 10,000 letters or a password with 10,000 characters, and so a character limit was important to fix the bug.
