Pwn2Own is an annual contest held with the idea of giving hackers the opportunity to present vulnerabilities of the most important operating systems in the world, but to earn money from them, even from the companies that produce them. Although Apple does not participate with prizes, those from Google or Microsoft do, but now we are talking about the Safari browser of those from Cupertino, it being exploited on the second day of Pwn2Own, a hacker named Jung Hoon Lee exploiting a vulnerability of to.
The hacker won $50.000 based on the Safari exploit presented in Pwn2Own, and some believe as the demonstration made by him was the basis of the recent updates of the Safari browsers for various versions of the OS X operating system. Apart from Safari and Google Chrome, it was exploited by hackers, so even those from Google have no peace during next, they being forced to solve their problems with publicly distributed software.
Lee wasn't done and went on to bolster his daily total to $225,000 later in the day by using a use-after-free vulnerability to take down Safari. Lee exploited an uninitialized stack pointer in the browser, something that bypassed its sandbox and netted him an additional $50,000.
Considering that a hacker can earn up to 225.000 dollars, like the one mentioned before, we can understand why some avoid releasing jailbreak solutions and prefer to sell their exploits or present them in competitions of this kind.
