Teams from Beijing security firm, Qihoo and South Korean Hacker Lokihardt both managed to compromise the Microsoft Edge browser on Windows, and bagged bounties of $120,000 each. Each team or contenstant is given three attempts to compromise the target, with each attempt having a time limit of four minutes. Lokihardt managed to gain system level access in as little as 18 seconds.
The hacks were showcased at PwnFest , an event related to the ongoing Power of the Community information security conference in Seoul, Korea, according to a report in The Register. It was the first time that a VMware Workstation was successfully attacked with only remote code execution, and no interaction by the end user.
The PwnFest is a yearly event where major tech companies offer rewards to hackers for owning certain products. Targets for the hackers this year included Microsoft Edge, Google Pixel, Microsoft Hyper-V, Google Chrome, iOS, the Safari browser, Adobe Flash and VMWare Workstation. The event also has a Lord of Pwn trophy given to the team with the most successful attacks, and if there is a tie, the award is decided based on technical merit of the hacks.
The prize money ranges from $80,000 for the Safari hack, to $150,000 for the VMWare and the Hyper-V attacks. The exploits are not publicly disclosed, and the companies usually take measures to plug these security holes.
