Guang Gong is the first to report an Android exploit chain after Google introduced bigger cash rewards for finding bugs. He reported the bugs to the Android security team back in August 2017, and the fix was released as a part of the December security update. The affected devices with security patch level of 2017-12-05 are safe from the exploit. At Pwn2Own 2016, Gong’s Qihoo 360 Alpha team won a cash prize of $120,000 for taking down a Pixel in just 60 seconds.”]
