A SERIES OF leaks has rocked the National Security Agency over the past few years, resulting in digital spy tools strewn across the web that have caused real damage both inside and outside the agency. Many of the breaches have been relatively simple to carry out, often by contractors like the whistleblower Edward Snowden, who employed just a USB drive and some chutzpah. But the most recently revealed breach, which resulted in state secrets reportedly being stolen by Russian spies, was caused by an NSA employee who pleaded guilty Friday to bringing classified information to his home, exposing it in the process. And all, reportedly, to update his resume.
