HonorPoncaCityDotCom writes "Nicole Perlroth and David E. Sanger write in the NY Times that all over the world, from South Africa to South Korea, business is booming in zero days. The average attack persists for almost a year before it is detected, according to Symantec, the maker of antivirus software. Until then it can be exploited or 'weaponized' by both criminals and governments to spy on, steal from, or attack their targets. Ten years ago, hackers would hand knowledge of such flaws to Microsoft and Google free in exchange for a T-shirt, but increasingly the market for 0-day exploits has begun to migrate into the commercial space (PDF) as the market for information about computer vulnerabilities has turned into a gold rush. Companies like Vupen charge customers an annual $100,000 subscription fee to shop through its catalog, and then charges per sale to countries who want to use the flaws in pursuit of the kind of success that the United States and Israel achieved three summers ago when they attacked Iran's nuclear enrichment program with a computer worm that became known as 'Stuxnet.' Israel, Britain, Russia, India and Brazil are some of the biggest spenders but North Korea is also in the market, as are some Middle Eastern intelligence services."
