Government and private-sector sources reveal the hidden casualties and costs of the world’s first known cyber-war,between the U.S. and Iran.

On the hidden battlefields of history’s first known cyber-war, the casualties are piling up. In the U.S., many banks have been hit, and the telecommunications industry seriously damaged, likely in retaliation for several major attacks on Iran. Washington and Tehran are ramping up their cyber-arsenals, built on a black-market digital arms bazaar, enmeshing such high-tech giants as Microsoft, Google, and Apple. With the help of highly placed government and private-sector sources, Michael Joseph Gross describes the outbreak of the conflict, its escalation, and its startling paradox: that America’s bid to stop nuclear proliferation may have unleashed a greater threat.
