‘[…] The Office of Tailored Access Operations, or TAO […] is the NSA’s top operative unit — something like a squad of plumbers that can be called in when normal access to a target is blocked.
According to internal NSA documents viewed by SPIEGEL, these on-call digital plumbers are involved in many sensitive operations conducted by American intelligence agencies. TAO’s area of operations ranges from counterterrorism to cyber attacks to traditional espionage. The documents reveal just how diversified the tools at TAO’s disposal have become — and also how it exploits the technical weaknesses of the IT industry, from Microsoft to Cisco and Huawei, to carry out its discreet and efficient attacks.
The unit is “akin to the wunderkind of the US intelligence community,” says Matthew Aid, a historian who specializes in the history of the NSA. “Getting the ungettable” is the NSA’s own description of its duties. “It is not about the quantity produced but the quality of intelligence that is important,” one former TAO chief wrote, describing her work in a document. The paper seen by SPIEGEL quotes the former senior official stating that TAO has contributed “some of the most significant intelligence our country has ever seen.” The unit, it goes on, has “access to our very hardest targets.”
Defining the future of her unit at the time, she wrote that TAO “needs to continue to grow and must lay the foundation for integrated Computer Network Operations,” and that it must “support Computer Network Attacks as an integrated part of military operations.” To succeed in this, she wrote, TAO would have to acquire “pervasive, persistent access on the global network.” An internal description of TAO’s responsibilities makes clear that aggressive attacks are an explicit part of the unit’s tasks. In other words, the NSA’s hackers have been given a government mandate for their work. During the middle part of the last decade, the special unit succeeded in gaining access to 258 targets in 89 countries — nearly everywhere in the world. In 2010, it conducted 279 operations worldwide.
Indeed, TAO specialists have directly accessed the protected networks of democratically elected leaders of countries. They infiltrated networks of European telecommunications companies and gained access to and read mails sent over Blackberry’s BES email servers, which until then were believed to be securely encrypted. Achieving this last goal required a “sustained TAO operation,” one document states.
This TAO unit is born of the Internet — created in 1997, a time when not even 2 percent of the world’s population had Internet access and no one had yet thought of Facebook, YouTube or Twitter. From the time the first TAO employees moved into offices at NSA headquarters in Fort Meade, Maryland, the unit was housed in a separate wing, set apart from the rest of the agency. Their task was clear from the beginning — to work around the clock to find ways to hack into global communications traffic.
To do this, the NSA needed a new kind of employee. The TAO workers authorized to access the special, secure floor on which the unit is located are for the most part considerably younger than the average NSA staff. Their job is breaking into, manipulating and exploiting computer networks, making them hackers and civil servants in one. Many resemble geeks — and act the part too.
Indeed, it is from these very circles that the NSA recruits new hires for its Tailored Access Operations unit. In recent years, NSA Director Keith Alexander has made several appearances at major hacker conferences in the United States. Sometimes, Alexander wears his military uniform, but at others, he even dons jeans and a t-shirt in his effort to court trust and a new generation of employees. […]
