Citing internal NSA documents, the magazine said Sunday that TAO’s mission was “Getting the ungettable,” and quoted an unnamed intelligence official as saying that TAO had gathered “some of the most significant intelligence our country has ever seen.”

Der Spiegel said TAO had a catalog of high-tech gadgets for particularly hard-to-crack cases, including computer monitor cables specially modified to record what is being typed across the screen, USB sticks secretly fitted with radio transmitters to broadcast stolen data over the airwaves, and fake base stations intended to intercept mobile phone signals on the go.

The NSA doesn’t just rely on James Bond-style spy gear, the magazine said. Some of the attacks described by Der Spiegel exploit weaknesses in the architecture of the Internet to deliver malicious software to specific computers. Others take advantage of weaknesses in hardware or software distributed by some of the world’s leading information technology companies, including Cisco Systems, Inc. and China’s Huawei Technologies Ltd., the magazine reported.
