NSA surveillance reach broader than acknowledged

The National Security Agency's surveillance network has the capacity to spy on 75 percent of all U.S. Internet traffic, The Wall Street Journal reports.

Citing current and former NSA officials for the 75 percent figure, the paper reported that the agency can observe more of Americans' online communications than officials have publicly acknowledged.

The NSA's system of programs that filter communications, achieved with the help of telecommunications companies, is designed to look for communications that either start or end abroad, or happen to pass through the U.S. between foreign countries. However, the officials told the Journal that the system's reach is so broad, that it is more likely that purely domestic communications will be intercepted as a byproduct of the hunt for foreign ones.

The system works by using algorithms that act as filters, designed to let high-value information through amid more benign chatter. However, after the Sept. 11, 2001 terror attacks, a former to intelligence official told the Journal that the government changed its definition of "reasonable" intelligence collection, enabling the NSA to widen the holes in the "filtering" system.

Thousands of technology, finance and manufacturing companies are working closely with U.S. national security agencies, providing sensitive information and in return receiving benefits that include access to classified intelligence, four people familiar with the process said.

These programs, whose participants are known as trusted partners, extend far beyond what was revealed by Edward Snowden, a computer technician who did work for the National Security Agency. The role of private companies has come under intense scrutiny since his disclosure this month that the NSA is collecting millions of U.S. residents’ telephone records and the computer communications of foreigners from Google Inc (GOOG). and other Internet companies under court order.

Many of these same Internet and telecommunications companies voluntarily provide U.S. intelligence organizations with additional data, such as equipment specifications, that don’t involve private communications of their customers, the four people said.

Makers of hardware and software, banks, Internet security providers, satellite telecommunications companies and many other companies also participate in the government programs. In some cases, the information gathered may be used not just to defend the nation but to help infiltrate computers of its adversaries. Read more >>
