The Qihoo 360 compromised Edge by escaping the Windows virtual machine it runs on or the VMware. This was accomplished by exploiting the heap overflow bug in the Windows kernel of Edge and the uninitialized buffer vulnerability in VMWare. The team received $105,000 cash prize for their exploits amidst other notable hacks from Trend Micro's Zero Day Initiative Group, the Pwn2Own hackers contest organizer. The contest tries to replicate how a real-world zero-day market would be and how the tech community can better prepare for it.
