Has The NSA Penetrated Cable Internet?
Security experts believe that the NSA has gotten in a vulnerable “back door” in Internet security — electronics connected to the fiber-optic cables to and from their data centers:
The recent revelation that the National Security Agency was able to eavesdrop on the communications of Google and Yahoo users without breaking into either companies’ data centers sounded like something pulled from a Robert Ludlum spy thriller.
How on earth, the companies asked, did the N.S.A. get their data without them knowing about it?
The most likely answer is a modern spin on a century-old eavesdropping tradition.
People knowledgeable about Google and Yahoo’s infrastructure say they believe that government spies bypassed the big Internet companies and hit them at a weak spot — the fiber-optic cables that connect data centers around the world that are owned by companies like Verizon Communications, the BT Group, the Vodafone Group and Level 3 Communications. In particular, fingers have been pointed at Level 3, the world’s largest so-called Internet backbone provider, whose cables are used by Google and Yahoo.
The Internet companies’ data centers are locked down with full-time security and state-of-the-art surveillance, including heat sensors and iris scanners. But between the data centers — on Level 3’s fiber-optic cables that connected those massive computer farms — information was unencrypted and an easier target for government intercept efforts, according to three people with knowledge of Google’s and Yahoo’s systems who spoke on the condition of anonymity.
It is impossible to say for certain how the N.S.A.
