Washington - The National Security Agency has been sifting
through millions of contact lists from personal email and instant messaging
accounts around the world — including those of Americans — in its effort to
find possible links to terrorism or other criminal activity, according to a
published report.
The Washington Post reported late Monday that the spy agency
intercepts hundreds of thousands of email address books every day from private
accounts on Yahoo, Gmail, Facebook and Hotmail that move though global data
links. The NSA also collects about a half million buddy lists from live chat
services and email accounts.
The Post said it learned about the collection tactics from
secret documents provided by NSA leaker Edward Snowden and confirmed by senior
intelligence officials. It was the latest revelation of the spy agency’s
practices to be disclosed by Snowden, the former NSA systems analyst who fled
the U.S. and now resides in Russia.
The newspaper said the NSA analyzes the contacts to map
relationships and connections among various foreign intelligence targets.
During a typical day last year, the NSA’s Special Source Operations branch
collected more than 440,000 email address books, the Post said. That would
correspond to a rate of more than 250 million a year.
A spokesman for the national intelligence director’s office,
which oversees the NSA, told the Post that the agency was seeking intelligence
on valid targets and was not interested in personal information from ordinary
Americans.
Spokesman Shawn Turner said the NSA was guided by rules that
require the agency to “minimize the acquisition, use and dissemination” of
information that identifies U.S. citizens or permanent residents.
While the collection was taking place overseas, the Post
said it encompassed the contact lists of many American users. The spy agency
obtains the contact lists through secret arrangements with foreign
telecommunications companies or other services that control Internet traffic,
the Post reported.
Earlier this year, Snowden gave documents to the Post and
Britain’s Guardian newspaper disclosing U.S. surveillance programs that collect
vast amounts of phone records and online data in the name of foreign
intelligence, often sweeping up information on American citizens.
The collection of contact lists in bulk would be illegal if
done in the United States, but the Post said the agency can get around that
restriction by intercepting lists from access points around the world.
The newspaper quoted a senior intelligence official as
saying NSA analysts may not search or distribute information from the contacts
database unless they can “make the case that something in there is a valid
foreign intelligence target in and of itself.”
