The annual competition, the 'Tianfu Cup', which is held in the Sichuan province of Chengdu, has been the go-to for China's elite hackers since they were banned from participating in similar competitive hacking events outside of their country.
The zero-day vulnerabilities were exploited by the Kunlun Lab and Team Pangu in a matter of seconds at the Tianfu Cup. The teams showed off a remote code execution attack and the first iOS 15 jailbreak.
Other than just the attacks on Apple's iOS 15 and Safari there were a whole host of other high value victims. These included Microsoft, which saw five successful exploits involving the Windows 10 operating system and one impacting Microsoft Exchange. Google was also breached, which saw Chrome succumb twice.
But the list is far from over: Adobe PDF, the Asus AX56U router, Docker CE, Parallels VM, QEMA VM, Ubuntu 20, VMware ESXi and Workstation were also successfully hacked in very little time.
Full details of the vulnerabilities exploited and the exploits themselves will filter into the public domain in the coming months. Meanwhile, full disclosure of the security flaws would have been immediately made to all the affected vendors.
