At the 2020 Tianfu Cup International PWN Contest, which took place earlier this month in China, participants earned a total of more than $1.2 million for exploits targeting Chrome, Safari, Firefox, Adobe Reader, Docker, VMware ESXi, CentOS, the iPhone, the Samsung Galaxy S20 phone, Windows, and routers from TP-Link and Asus.

The 360 ESG Vulnerability Research Institute from Chinese cybersecurity company Qihoo 360 earned more than $740,000 of the total, including $180,000 for a VMware ESXi guest to host escape exploit.
