A new kind of hijacking in cyberspace?

This from the FBI Newark Division's "National Security THreat Awareness Monthly Bulletin" for November 2010:

(U) Cyber Experts Have Proof That China Has Hijacked US-Based Internet Traffic (National
Defense Magazine, 12 NOV 2010)
(U) For 18 minutes in April, China’s state-controlled telecommunications company hijacked 15 percent of the world’s Internet traffic, including data from US military, civilian organizations and those of other US
allies. This massive redirection of data has received scant attention in the mainstream media because the mechanics of how the hijacking was carried out and the implications of the incident are difficult for those outside the cybersecurity community to grasp, said a top security expert at McAfee, the world’s largest dedicated Internet security company. In short, the Chinese could have carried out eavesdropping on unprotected communications, including emails and instant messaging, manipulated data passing through their country or decrypted messages, the vice president of threat research at McAfee said.
(U) Nobody outside of China can say, at least publicly, what happened to the terabytes of data after the traffic entered China. The incident may receive more attention when the US-China Economic and Security Review Commission, a congressional committee, releases its annual report on the bilateral relationship in November. A commission press release said the 2010 report will address “the increasingly sophisticated nature of malicious computer activity associated with China.” Said the McAfee vice president: “This is one of the biggest, if not the biggest hijacks, we have ever seen.” And it could happen again, anywhere and anytime. It’s just the way the Internet works, he explained. “What happened to the traffic while it was in China? No one knows.”
(U) The telephone giants of the world work on a system based on trust, he explained. Machine-to- machine interfaces send out messages to the Internet informing other service providers that they are the fastest and most efficient way for data packets to travel. For 18 minutes on April 8, China Telecom Corp. told many ISPs of the world that its routes were the best paths to send traffic. For example, a person sending information from Arlington, Va., to the White House in Washington, D.C., only a few miles away, could have had the data routed through China. Since traffic moves around the world in milliseconds, the computer user would not have noticed the delay.
