The National Security Agency has secretly broken into the main communications links that connect Yahoo and Google data centers around the world, a newspaper reported, citing documents obtained from former NSA contractor Edward Snowden.
A secret accounting dated Jan. 9, 2013, indicates that NSA sends millions of records every day from Yahoo and Google internal networks to data warehouses at the agency's Fort Meade, Maryland, headquarters, the Washington Post reported Wednesday.
In the last 30 days, field collectors had processed and sent back more than 180 million new records - ranging from "metadata," which would indicate who sent or received emails and when, to content such as text, audio and video, the Post reported Wednesday on its website.
The latest revelations were met with outrage from Google, and triggered legal questions, including whether the NSA may be violating federal wiretap laws.
"Although there's a diminished standard of legal protection for interception that occurs overseas, the fact that it was directed apparently to Google's cloud and Yahoo's cloud, and that there was no legal order as best we can tell to permit the interception, there is a good argument to make that the NSA has engaged in unlawful surveillance," said Marc Rotenberg, executive director of Electronic Privacy Information Center. The reference to 'clouds' refers to sites where the companies collect data.
The new details about the NSA's access to Yahoo and Google data centers around the world come at a time when the US Congress is reconsidering the government's collection practices and authority, and as European governments are responding angrily to revelations that the NSA collected data on millions of communications in their countries.
