Snowden Files: NSA Holds Keys to Most Web Encryption

By James Ball, Julian Borger and Glenn Greenwald, Guardian UK

S and British intelligence agencies have successfully cracked much of the online encryption relied upon by hundreds of millions of people to protect the privacy of their personal data, online transactions and emails, according to top-secret documents revealed by former contractor Edward Snowden.

The files show that the National Security Agency and its UK counterpart GCHQ have broadly compromised the guarantees that internet companies have given consumers to reassure them that their communications, online banking and medical records would be indecipherable to criminals or governments.

The agencies, the documents reveal, have adopted a battery of methods in their systematic and ongoing assault on what they see as one of the biggest threats to their ability to access huge swathes of internet traffic - "the use of ubiquitous encryption across the internet".

Those methods include covert measures to ensure NSA control over setting of international encryption standards, the use of supercomputers to break encryption with "brute force", and - the most closely guarded secret of all - collaboration with technology companies and internet service providers themselves.

Through these covert partnerships, the agencies have inserted secret vulnerabilities - known as backdoors or trapdoors - into commercial encryption software.

The files, from both the NSA and GCHQ, were obtained by the Guardian, and the details are being published today in partnership with the New York Times and ProPublica. They reveal:

  • A 10-year NSA program against encryption technologies made a breakthrough in 2010 which made "vast amounts" of data collected through internet cable taps newly "exploitable".
  • The NSA spends $250m a year on a program which, among other goals, works with technology companies to "covertly influence" their product designs.
  • The secrecy of their capabilities against encryption is closely guarded, with analysts warned: "Do not ask about or speculate on sources or methods."
  • The NSA describes strong decryption programs as the "price of admission for the US to maintain unrestricted access to and use of cyberspace".
  • A GCHQ team has been working to develop ways into encrypted traffic on the "big four" service providers, named as Hotmail, Google, Yahoo and Facebook.

The agencies insist that the ability to defeat encryption is vital to their core missions of counter-terrorism and foreign intelligence gathering.

But security experts accused them of attacking the internet itself and the privacy of all users. "Cryptography forms the basis for trust online," said Bruce Schneier, an encryption specialist and fellow at Harvard's Berkman Center for Internet and Society. "By deliberately undermining online security in a short-sighted effort to eavesdrop, the NSA is undermining the very fabric of the internet." Classified briefings between the agencies celebrate their success at "defeating network security and privacy".

"For the past decade, NSA has lead [sic] an aggressive, multi-pronged effort to break widely used internet encryption technologies," stated a 2010 GCHQ document. "Vast amounts of encrypted internet data which have up till now been discarded are now exploitable."

An internal agency memo noted that among British analysts shown a presentation on the NSA's progress: "Those not already briefed were gobsmacked!"

The breakthrough, which was not described in detail in the documents, meant the intelligence agencies were able to monitor "large amounts" of data flowing through the world's fibre-optic cables and break its encryption, despite assurances from internet company executives that this data was beyond the reach of government.

The key component of the NSA's battle against encryption, its collaboration with technology companies, is detailed in the US intelligence community's top-secret 2013 budget request under the heading "Sigint [signals intelligence] enabling".

Funding for the program - $254.9m for this year - dwarfs that of the Prism program, which operates at a cost of $20m a year, according to previous NSA documents. Since 2011, the total spending on Sigint enabling has topped $800m. The program "actively engages US and foreign IT industries to covertly influence and/or overtly leverage their commercial products' designs", the document states. None of the companies involved in such partnerships are named; these details are guarded by still higher levels of classification.

Among other things, the program is designed to "insert vulnerabilities into commercial encryption systems". These would be known to the NSA, but to no one else, including ordinary customers, who are tellingly referred to in the document as "adversaries".

"These design changes make the systems in question exploitable through Sigint collection ... with foreknowledge of the modification. To the consumer and other adversaries, however, the systems' security remains intact."

The document sets out in clear terms the program's broad aims, including making commercial encryption software "more tractable" to NSA attacks by "shaping" the worldwide marketplace and continuing efforts to break into the encryption used by the next generation of 4G phones.

Among the specific accomplishments for 2013, the NSA expects the program to obtain access to "data flowing through a hub for a major communications provider" and to a "major internet peer-to-peer voice and text communications system".

Technology companies maintain that they work with the intelligence agencies only when legally compelled to do so. The Guardian has previously reported that Microsoft co-operated with the NSA to circumvent encryption on the Outlook.com email and chat services. The company insisted that it was obliged to comply with "existing or future lawful demands" when designing its products.

The documents show that the agency has already achieved another of the goals laid out in the budget request: to influence the international standards upon which encryption systems rely.

Independent security experts have long suspected that the NSA has been introducing weaknesses into security standards, a fact confirmed for the first time by another secret document. It shows the agency worked covertly to get its own version of a draft security standard issued by the US National Institute of Standards and Technology approved for worldwide use in 2006.

"Eventually, NSA became the sole editor," the document states.

The NSA's codeword for its decryption program, Bullrun, is taken from a major battle of the American civil war. Its British counterpart, Edgehill, is named after the first major engagement of the English civil war, more than 200 years earlier.

A classification guide for NSA employees and contractors on Bullrun outlines in broad terms its goals.

"Project Bullrun deals with NSA's abilities to defeat the encryption used in specific network communication technologies. Bullrun involves multiple sources, all of which are extremely sensitive." The document reveals that the agency has capabilities against widely used online protocols, such as HTTPS, voice-over-IP and Secure Sockets Layer (SSL), used to protect online shopping and banking.

The document also shows that the NSA's Commercial Solutions Center, ostensibly the body through which technology companies can have their security products assessed and presented to prospective government buyers, has another, more clandestine role.

It is used by the NSA to "to leverage sensitive, co-operative relationships with specific industry partners" to insert vulnerabilities into security products. Operatives were warned that this information must be kept top secret "at a minimum".

A more general NSA classification guide reveals more detail on the agency's deep partnerships with industry, and its ability to modify products. It cautions analysts that two facts must remain top secret: that NSA makes modifications to commercial encryption software and devices "to make them exploitable", and that NSA "obtains cryptographic details of commercial cryptographic information security systems through industry relationships".

The agencies have not yet cracked all encryption technologies, however, the documents suggest. Snowden appeared to confirm this during a live Q&A with Guardian readers in June. "Encryption works. Properly implemented strong crypto systems are one of the few things that you can rely on," he said before warning that NSA can frequently find ways around it as a result of weak security on the computers at either end of the communication.

The documents are scattered with warnings over the importance of maintaining absolute secrecy around decryption capabilities.

Strict guidelines were laid down at the GCHQ complex in Cheltenham, Gloucestershire, on how to discuss projects relating to decryption. Analysts were instructed: "Do not ask about or speculate on sources or methods underpinning Bullrun." This informaton was so closely guarded, according to one document, that even those with access to aspects of the program were warned: "There will be no 'need to know'."

The agencies were supposed to be "selective in which contractors are given exposure to this information", but it was ultimately seen by Snowden, one of 850,000 people in the US with top-secret clearance.A 2009 GCHQ document spells out the significant potential consequences of any leaks, including "damage to industry relationships".

"Loss of confidence in our ability to adhere to confidentiality agreements would lead to loss of access to proprietary information that can save time when developing new capability," intelligence workers were told. Somewhat less important to GCHQ was the public's trust which was marked as a moderate risk, the document stated.

"Some exploitable products are used by the general public; some exploitable weaknesses are well known eg possibility of recovering poorly chosen passwords," it said. "Knowledge that GCHQ exploits these products and the scale of our capability would raise public awareness generating unwelcome publicity for us and our political masters."

The decryption effort is particularly important to GCHQ. Its strategic advantage from its Tempora program - direct taps on transatlantic fibre-optic cables of major telecommunications corporations - was in danger of eroding as more and more big internet companies encrypted their traffic, responding to customer demands for guaranteed privacy.

Without attention, the 2010 GCHQ document warned, the UK's "Sigint utility will degrade as information flows changes, new applications are developed (and deployed) at pace and widespread encryption becomes more commonplace." Documents show that Edgehill's initial aim was to decode the encrypted traffic certified by three major (unnamed) internet companies and 30 types of Virtual Private Network (VPN) - used by businesses to provide secure remote access to their systems. By 2015, GCHQ hoped to have cracked the codes used by 15 major internet companies, and 300 VPNs.

Another program, codenamed Cheesy Name, was aimed at singling out encryption keys, known as 'certificates', that might be vulnerable to being cracked by GCHQ supercomputers.

Analysts on the Edgehill project were working on ways into the networks of major webmail providers as part of the decryption project. A quarterly update from 2012 notes the project's team "continue to work on understanding" the big four communication providers, named in the document as Hotmail, Google, Yahoo and Facebook, adding "work has predominantly been focused this quarter on Google due to new access opportunities being developed".

To help secure an insider advantage, GCHQ also established a Humint Operations Team (HOT). Humint, short for "human intelligence" refers to information gleaned directly from sources or undercover agents.

This GCHQ team was, according to an internal document, "responsible for identifying, recruiting and running covert agents in the global telecommunications industry."

"This enables GCHQ to tackle some of its most challenging targets," the report said. The efforts made by the NSA and GCHQ against encryption technologies may have negative consequences for all internet users, experts warn.

"Backdoors are fundamentally in conflict with good security," said Christopher Soghoian, principal technologist and senior policy analyst at the American Civil Liberties Union. "Backdoors expose all users of a backdoored system, not just intelligence agency targets, to heightened risk of data compromise." This is because the insertion of backdoors in a software product, particularly those that can be used to obtain unencrypted user communications or data, significantly increases the difficulty of designing a secure product."

This was a view echoed in a recent paper by Stephanie Pell, a former prosecutor at the US Department of Justice and non-resident fellow at the Center for Internet and Security at Stanford Law School.

"[An] encrypted communications system with a lawful interception back door is far more likely to result in the catastrophic loss of communications confidentiality than a system that never has access to the unencrypted communications of its users," she states.

Intelligence officials asked the Guardian, New York Times and ProPublica not to publish this article, saying that it might prompt foreign targets to switch to new forms of encryption or communications that would be harder to collect or read.

The three organisations removed some specific facts but decided to publish the story because of the value of a public debate about government actions that weaken the most powerful tools for protecting the privacy of internet users in the US and worldwide.


 

Comments   

We are concerned about a recent drift towards vitriol in the RSN Reader comments section. There is a fine line between moderation and censorship. No one likes a harsh or confrontational forum atmosphere. At the same time everyone wants to be able to express themselves freely. We'll start by encouraging good judgment. If that doesn't work we'll have to ramp up the moderation.

General guidelines: Avoid personal attacks on other forum members; Avoid remarks that are ethnically derogatory; Do not advocate violence, or any illegal activity.

Remember that making the world better begins with responsible action.

. . . celebrate their success at "defeating network security and privacy", "no 'need to know", "public awareness generating unwelcome publicity for us and our political masters", "the consumer and other adversaries" . . .

These are not our friends.

You're right, tedrey! Corporations have successfully approached our elected representatives in order to enact “anti-piracy” laws to protect their interests. Now we learn, (more thanks to Edward Snowden), that “Joe and Josephine Citizen” have their most private internet transactions “pirated” by the NSA and GCHQ! Once again, the greed of corporations supersede and trump the Constitutional guaranteed rights to privacy of our citizens.

yes, govt's intentions are usually pretty clear from the operation names -- it's often the site of military hubris. Remember "Operation Iraqi Liberation" (OIL)? Using the first civil war battles as joint code names strongly suggests both govts view this as a civil war, in this case WE are the enemy. So I sound a little paranoid, but their own words seem to indicate this is a civil war in progress. It is nothing less than establishing the means of power for big brother and the corporate state to control the global population.

This is also going to mean a lot more hacking--if the back doors exist, you can bet they are going to be found & exploited, irregardless of whether this story was published. How many major commercial hackers are ex-intel folks? (rsn posted a recent story about one of these guys). Hackers aren't just idealists, they are becoming mercenaries used by corporations & govts to target dissidents, activists, & opinion-shapers.

Finally, how is it that so many IT people have been compromised and turned into whores by the govt? Fear? Ignorant "patriotism"? Stupidity? Has their loyalty been purchased or gained by threat? Or do they not give a shit?

Is open source the answer here? Open the codes so that all users can explore and fix vulnerabilities .

This won't lead anywhere. People still have to go out, buy their groceries. They're not gonna give up computers or the internet. Clearly the global situation is fracked and it won't get better.
Surveillability is the new privacy. At heart we're all romantics who grew up on Hollywood shiite and can't get it out of our system. No wonder the kids have turned to zombies for realism.

Well. It was a good 10 year run of the free internet before the people who feared it the most (government) and the people who coveted control of it the most (businessmen) ruined it for everyone forevermore.

Imaginary sources have recently come forward claiming that Smowden is a CIA operative, spreading disinformation in order to create widespread fear of the the surveillance capabilities of the US government. The Feds decided that it would be more efficient to scare everyone into compliance than to actually do their jobs.

Wouldn't that be interesting?

"Operation Cheesy Name". Now that's funny

So this is the true nature of the US/UK "Special Relationship", eh?
-And from all we hear, they are spying on each other too.
Remember the old "Mad Magazine" cartoon feature "Spy vs Spy", in which two long-nosed, cloaked and wide-brim-hatte d spy-caricatured characters kept plotting and counter-plottin g against each other? Well, this is about the same thing couched in hi-tech terms and I take it all about as seriously, except unlike the authors of "Spy vs. Spy", the perpe-traitors (spelling deliberate) are lacking in any sense of humor and the ridiculous, or they wouldn't pursue it at all, so stupid does it make them look, especially each and every time their leaders waffle on about "Democracy", "Freedoms" and "Rogue States being permitted to have lethal weapons".
The actual technical explanations provided here give me brain-damage but I'm glad that smarter, more 'au courant' individuals like Snowden are able and willing to expose the establishment's spoiled-child-b ully's squandering of our taxes on bogus, social-control and engineering, fear-inspiring (in the gullible) tactics for the global totalitarian aspirations of their corporate-milit ary overlords.
Again, "Ah fart in their general direction" (Monty Python)!

Again I say: I don't care if the government has the ability to scrutinize my every post, text and/or phone call (because I am certain that I'm not worth the cost of doing so). But, as of this article I am holding my breath against the day when some hacker steals the encryption breaking tools from the NSA and uses them to hack my accounts and steal what I have (because I'm certain that for such people their time will be well rewarded in that fashio and I truly have no recourse).

The Gov't is giving your tax dollars to private companies who are taking your country from you. The Axis of Evil is now the GOP, NSA, and Corporate America.

No, as far as they can see, "the axis of evil" is every family in america (and the world)

Well, what a wet dream for a Corporatist !

The consumer (unlike other "adversaries") must pay top dollar for the computer that is *designed* to accommodate Big Brother capability, top dollar for all of the software designed to exploit and abuse the consumer, top dollar for all of the encryption systems that are sold under the rubric of *disabusing* the consumer of NSA intrusion, but which are also *shared with* the NSA, and top dollar for all of the *TAXES* used to fund the NSA, while it blows millions on bribes for the computer and software makers !

I'm just touching the highlights here, because it is beyond the scope of this comment to include all of the hardworking middlemen involved in this scam, who are also lining their own nests from the taxpayers' wallet.

No wonder we are fighting to put all of our Senior Citizens out on some kind of an Ice Floe, frantically canceling meals for poor children, and food stamps for anybody.

When you are living in a society that spends most of its resources on military and security issues, when the corporate element in society works hand in glove with the government to monopolize markets, when a government agency knows more about you and your interests than your family, when dissent is fully monitored and almost instantly destroyed, you have what used to be known as a fascist society. Orwell's fantasy is fantasy no more. It becomes a reality that makes it difficult to live with EVEN when there is an 18th Century constitution and republican form of government.
