PHILADELPHIA (CBS) — We’re learning some details today about a top-secret National Security Agency program, called XKeyscore, that appears to give the government a window into what we do online.
In presentation slides provided to The Guardian newspaper by Edward Snowden, the NSA explains how analysts can search through databases of web sites visited, e-mails, chats, and social networking activity — or, as the agency says, “nearly everything a typical user does on the Internet.”
The information can’t legally target Americans without a warrant, but the newspaper says NSA analysts don’t go before a court or even a supervisor before performing a search; instead, they need only provide a broad justification in a pull-down menu — as easily as the rest of us might select “Mr.” or “Mrs.” on a web form.
Since there’s so much data taken from network sites around the world, The Guardian says, most of it is stored only for a short period of time — though analysts can flag “interesting” traffic and hold it for years.
The NSA says 300 terrorists have been taken down over the past five years using information from XKeyscore.
