Researchers Bruno Keith and Niklas Baumstark, from Dataflow Security, were awarded US $ 100,000 on the second day of the competition, for exploiting flaws in Chrome and Microsoft Edge browsers.

On the first day, attempts to hack the Parallels virtual machine failed, but on the second day, researcher Jack Dates, from RET2 Systems, and also Sunjoo Park, earned $ 40,000 each from being able to run code on the underlying operating system through the application. Parallels Desktop.

There have also been two successful attempts to escalate privileges in Windows 10 and a successful exploitation of privilege escalation in Ubuntu. These participants won $ 40,000 and $ 30,000, respectively.
