A zero-day exploit for Adobe Reader can go for $5,000 or $30,000, while an exploit for the Mac OS can cost $50,000. But an exploit for Flash or Windows can jump to $100,000 or more because of the programs’ ubiquity in the marketplace. An exploit for Apple’s iOS can also go for $100,000 because the iPhone is more difficult to crack than competing mobile phones. Browser exploits that attack Firefox, Internet Explorer, and Chrome can sell for anywhere from $60,000 to more than $200,000, depending on their ability to bypass security protections the vendors have put in the software.1
