Forbes profiles Vupen, a French security firm that openly sells secret software exploits to spies and government agencies. Its customers pay a $100,000 annual fee simply for the privilege of paying extra fees for the exploits that Vupen's hackers develop, which the company says can penetrate every major browser, as well as other targets like iOS, Android, Adobe Reader and Microsoft Word.
