NSA Documents from the Spiegel Story

There are more source documents from the recent Spiegel story on the NSA than I realized. Here is what I think is the complete list:

Here are the news articles: Three English articles. Spy catalog interactive graphic. Two articles in German.

This is all really important information for those of us trying to defend against adversaries with these sorts of capabilities.

More about the NSA's Tailored Access Operations Unit

Der Spiegel has a good article on the NSA’s Tailored Access Operations unit: basically, its hackers.

“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 unit head 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.

[…]

Certainly, few if any other divisions within the agency are growing as quickly as TAO. There are now TAO units in Wahiawa, Hawaii; Fort Gordon, Georgia; at the NSA’s outpost at Buckley Air Force Base, near Denver, Colorado; at its headquarters in Fort Meade; and, of course, in San Antonio.

The article also has more details on how QUANTUM—particularly, QUANTUMINSERT—works.

Until just a few years ago, NSA agents relied on the same methods employed by cyber criminals to conduct these implants on computers. They sent targeted attack emails disguised as spam containing links directing users to virus-infected websites. With sufficient knowledge of an Internet browser’s security holes—Microsoft’s Internet Explorer, for example, is especially popular with the NSA hackers—all that is needed to plant NSA malware on a person’s computer is for that individual to open a website that has been specially crafted to compromise the user’s computer. Spamming has one key drawback though: It doesn’t work very often.

Nevertheless, TAO has dramatically improved the tools at its disposal. It maintains a sophisticated toolbox known internally by the name “QUANTUMTHEORY.” “Certain QUANTUM missions have a success rate of as high as 80%, where spam is less than 1%,” one internal NSA presentation states.

A comprehensive internal presentation titled “QUANTUM CAPABILITIES,” which SPIEGEL has viewed, lists virtually every popular Internet service provider as a target, including Facebook, Yahoo, Twitter and YouTube. “NSA QUANTUM has the greatest success against Yahoo, Facebook and static IP addresses,” it states. The presentation also notes that the NSA has been unable to employ this method to target users of Google services. Apparently, that can only be done by Britain’s GCHQ intelligence service, which has acquired QUANTUM tools from the NSA.

A favored tool of intelligence service hackers is “QUANTUMINSERT.”

[…]

Once TAO teams have gathered sufficient data on their targets’ habits, they can shift into attack mode, programming the QUANTUM systems to perform this work in a largely automated way. If a data packet featuring the email address or cookie of a target passes through a cable or router monitored by the NSA, the system sounds the alarm. It determines what website the target person is trying to access and then activates one of the intelligence service’s covert servers, known by the codename FOXACID.

This NSA server coerces the user into connecting to NSA covert systems rather than the intended sites. In the case of Belgacom engineers, instead of reaching the LinkedIn page they were actually trying to visit, they were also directed to FOXACID servers housed on NSA networks. Undetected by the user, the manipulated page transferred malware already custom tailored to match security holes on the target person’s computer.

The technique can literally be a race between servers, one that is described in internal intelligence agency jargon with phrases like: “Wait for client to initiate new connection,” “Shoot!” and “Hope to beat server-to-client response.” Like any competition, at times the covert network’s surveillance tools are “too slow to win the race.” Often enough, though, they are effective. Implants with QUANTUMINSERT, especially when used in conjunction with LinkedIn, now have a success rate of over 50 percent, according to one internal document.

Another article discusses the various tools TAO has at its disposal.

A document viewed by SPIEGEL resembling a product catalog reveals that an NSA division called ANT has burrowed its way into nearly all the security architecture made by the major players in the industry—including American global market leader Cisco and its Chinese competitor Huawei, but also producers of mass-market goods, such as US computer-maker Dell.

[…]

In the case of Juniper, the name of this particular digital lock pick is “FEEDTROUGH.” This malware burrows into Juniper firewalls and makes it possible to smuggle other NSA programs into mainframe computers. Thanks to FEEDTROUGH, these implants can, by design, even survive “across reboots and software upgrades.” In this way, US government spies can secure themselves a permanent presence in computer networks. The catalog states that FEEDTROUGH “has been deployed on many target platforms.”

[…]

Another program attacks the firmware in hard drives manufactured by Western Digital, Seagate, Maxtor and Samsung, all of which, with the exception of the latter, are American companies. Here, too, it appears the US intelligence agency is compromising the technology and products of American companies.

[…]

There is no information in the documents seen by SPIEGEL to suggest that the companies whose products are mentioned in the catalog provided any support to the NSA or even had any knowledge of the intelligence solutions.

The German version of the article had a couple of pages from the 50-page catalog of tools; they’re now on Cryptome. Leaksource has the whole TOP SECRET catalog; there’s a lot of really specific information here about individual NSA TAO ANT devices. (We don’t know what “ANT” stands for. Der Spiegel speculates that it “stands for Advanced or Access Network Technology.”) For example:

(TS//SI//REL) SOUFFLETROUGH is a BIOS persistence implant for Juniper SSG 500 and SSG 300 series firewalls. It persists DNT’s BANANAGLEE software implant. SOUFFLETROUGH also has an advanced persistent back-door capability.

And NIGHTSTAND:

(TS//SI//REL) An active 802.11 wireless exploitation and injection tool for payload/exploit delivery into otherwise denied target space. NIGHTSTAND is typically used in operations where wired access to the target is not possible.

NIGHTSTAND can work from as far away as eight miles, and “the attack is undetectable by the user.”

One more:

(TS//SI//REL) DROPOUTJEEP is a software implant for Apple iPhone that utilizes modular mission applications to provide specific SIGNIT functionality. This functionality includes the ability to remotely push/pull files from the device, SMS retrieval, contact list retrieval, voicemail, geolocation, hot mic, camera capture, cell tower location, etc. Command, control, and data exfiltration can occur over SMS messaging or a GPRS data connection. All communications with the implant will be covert and encrypted.

(TS//SI//REL) The initial release of DROPOUTJEEP will focus on installing the implant via close access methods. A remote installation capabilitiy will be pursued for a future release.

There’s lots more in the source document. And note that this catalog is from 2008; presumably, TAO’s capabilities have improved significantly in the past five years.

And—back to the first article—TAO can install many of the hardware implants when a target orders new equipment through the mail:

If a target person, agency or company orders a new computer or related accessories, for example, TAO can divert the shipping delivery to its own secret workshops. The NSA calls this method interdiction. At these so-called “load stations,” agents carefully open the package in order to load malware onto the electronics, or even install hardware components that can provide backdoor access for the intelligence agencies. All subsequent steps can then be conducted from the comfort of a remote computer.

These minor disruptions in the parcel shipping business rank among the “most productive operations” conducted by the NSA hackers, one top secret document relates in enthusiastic terms. This method, the presentation continues, allows TAO to obtain access to networks “around the world.”

They can install the software implants using techniques like QUANTUM and FOXACID.

Related is this list of NSA attack tools. And here is another article on TAO from October.

Remember, this is not just about the NSA. The NSA shares these tools with the FBI’s black bag teams for domestic surveillance, and presumably with the CIA and DEA as well. Other countries are going to have similar bags of tricks, depending on their sophistication and budgets. And today’s secret NSA programs are tomorrow’s PhD theses, and the next day’s criminal hacking tools. Even if you trust the NSA to only spy on “enemies,” consider this an advance warning of what we have to secure ourselves against in the future.

I’m really happy to see Jacob Appelbaum’s byline on the Der Spiegel stories; it’s good to have someone of his technical ability reading and understanding the documents.

Slashdot thread. Hacker News thread. MetaFilter thread. Ars Technica article. Wired article. Article on Appelbaum’s talk at 30c3.

EDITED TO ADD: Here’s Appelbaum’s talk. And three BoingBoing posts.

NSA Spying: Whom Do You Believe?

On Friday, Reuters reported that RSA entered into a secret contract to make DUAL_EC_PRNG the default random number generator in the BSAFE toolkit. DUA_EC_PRNG is now known to have been backdoored by the NSA.

Yesterday, RSA denied it:

Recent press coverage has asserted that RSA entered into a “secret contract” with the NSA to incorporate a known flawed random number generator into its BSAFE encryption libraries. We categorically deny this allegation.

[…]

We made the decision to use Dual EC DRBG as the default in BSAFE toolkits in 2004, in the context of an industry-wide effort to develop newer, stronger methods of encryption. At that time, the NSA had a trusted role in the community-wide effort to strengthen, not weaken, encryption.

We know from both Mark Klein and Edward Snowden—and pretty much everything else about the NSA—that the NSA directly taps the trunk lines of AT&T (and pretty much every other telcom carrier). On Friday, AT&T denied that:

In its statement, AT&T sought to push back against the notion that it provides the government with such access. “We do not allow any government agency to connect directly to our network to gather, review or retrieve our customers’ information,” said Watts.

I’ve written before about how the NSA has corroded our trust in the Internet and communications technologies. The debates over these companies’ statements, and about exactly how they are using and abusing individual words to lie while claiming they are not lying, is a manifestation of that.

Me again:

This sort of thing can destroy our country. Trust is essential in our society. And if we can’t trust either our government or the corporations that have intimate access into so much of our lives, society suffers. Study after study demonstrates the value of living in a high-trust society and the costs of living in a low-trust one.

Rebuilding trust is not easy, as anyone who has betrayed or been betrayed by a friend or lover knows, but the path involves transparency, oversight and accountability. Transparency first involves coming clean. Not a little bit at a time, not only when you have to, but complete disclosure about everything. Then it involves continuing disclosure. No more secret rulings by secret courts about secret laws. No more secret programs whose costs and benefits remain hidden.

Oversight involves meaningful constraints on the NSA, the FBI and others. This will be a combination of things: a court system that acts as a third-party advocate for the rule of law rather than a rubber-stamp organization, a legislature that understands what these organizations are doing and regularly debates requests for increased power, and vibrant public-sector watchdog groups that analyze and debate the government’s actions.

Accountability means that those who break the law, lie to Congress or deceive the American people are held accountable. The NSA has gone rogue, and while it’s probably not possible to prosecute people for what they did under the enormous veil of secrecy it currently enjoys, we need to make it clear that this behavior will not be tolerated in the future. Accountability also means voting, which means voters need to know what our leaders are doing in our name.

This is the only way we can restore trust. A market economy doesn’t work unless consumers can make intelligent buying decisions based on accurate product information. That’s why we have agencies like the FDA, truth-in-packaging laws and prohibitions against false advertising.

We no longer know whom to trust. This is the greatest damage the NSA has done to the Internet, and will be the hardest to fix.

EDITED TO ADD (12/23): The requested removal of an NSA employee from an IETF group co-chairmanship is another manifestation of this mistrust.

NSA Tracks People Using Google Cookies

The Washington Post has a detailed article on how the NSA uses cookie data to track individuals. The EFF also has a good post on this.

I have been writing and saying that surveillance is the business model of the Internet, and that government surveillance largely piggy backs on corporate capabilities. This is an example of that. The NSA doesn’t need the cooperation of any Internet company to use their cookies for surveillance purposes, but they do need their capabilities. And because the Internet is largely unencrypted, they can use those capabilities for their own purposes.

Reforming the NSA is not just about government surveillance. It has to address the public-private surveillance partnership. Even as a group of large Internet companies have come together to demand government surveillance reform, they are ignoring their own surveillance activities. But you can’t reform one without the other. The Free Software Foundation has written about this as well.

Little has been written about how QUANTUM interacts with cookie surveillance. QUANTUM is the NSA’s program for real-time responses to passive Internet monitoring. It’s what allows them to do packet injection attacks. The NSA’s Tor Stinks presentation talks about a subprogram called QUANTUMCOOKIE: “forces clients to divulge stored cookies.” My guess is that the NSA uses frame injection to surreptitiously force anonymous users to visit common sites like Google and Facebook and reveal their identifying cookies. Combined with the rest of their cookie surveillance activities, this can de-anonymize Tor users if they use Tor from the same browser they use for other Internet activities.

NSA Spying on Online Gaming Worlds

The NSA is spying on chats in World of Warcraft and other games. There’s lots of information—and a good source document. While it’s fun to joke about the NSA and elves and dwarves from World of Warcraft, this kind of surveillance makes perfect sense. If, as Dan Geer has pointed out, your assigned mission is to ensure that something never happens, the only way you can be sure that something never happens is to know everything that does happen. Which puts you in the impossible position of having to eavesdrop on every possible communications channel, including online gaming worlds.

One bit (on page 2) jumped out at me:

The NMDC engaged SNORT, an open source packet-sniffing software, which runs on all FORNSAT survey packet data, to filter out WoW packets. GCHQ provided several WoW protocol parsing scripts to process the traffic and produce Warcraft metadata from all NMDC FORNSAT survey.

NMDC is the New Mission Development Center, and FORNSAT stands for Foreign Satellite Collection. MHS, which also appears in the source document, stands for—I think—Menwith Hill Station, a satellite eavesdropping location in the UK.

Since the Snowden documents first started being released, I have been saying that while the US has a bigger intelligence budget than the rest of the world’s countries combined, agencies like the NSA are not made of magic. They’re constrained by the laws of mathematics, physics, and economics—just like everyone else. Here’s an example. The NSA is using Snort—an open source product that anyone can download and use—because that’s a more cost-effective tool than anything they can develop in-house.

The FBI Might Do More Domestic Surveillance than the NSA

This is a long article about the FBI’s Data Intercept Technology Unit (DITU), which is basically its own internal NSA.

It carries out its own signals intelligence operations and is trying to collect huge amounts of email and Internet data from U.S. companies—an operation that the NSA once conducted, was reprimanded for, and says it abandoned.

[…]

The unit works closely with the “big three” U.S. telecommunications companies—AT&T, Verizon, and Sprint—to ensure its ability to intercept the telephone and Internet communications of its domestic targets, as well as the NSA’s ability to intercept electronic communications transiting through the United States on fiber-optic cables.

[…]

After Prism was disclosed in the Washington Post and the Guardian, some technology company executives claimed they knew nothing about a collection program run by the NSA. And that may have been true. The companies would likely have interacted only with officials from the DITU and others in the FBI and the Justice Department, said sources who have worked with the unit to implement surveillance orders.

[…]

Recently, the DITU has helped construct data-filtering software that the FBI wants telecom carriers and Internet service providers to install on their networks so that the government can collect large volumes of data about emails and Internet traffic.

The software, known as a port reader, makes copies of emails as they flow through a network. Then, in practically an instant, the port reader dissects them, removing only the metadata that has been approved by a court.

The FBI has built metadata collection systems before. In the late 1990s, it deployed the Carnivore system, which the DITU helped manage, to pull header information out of emails. But the FBI today is after much more than just traditional metadata—who sent a message and who received it. The FBI wants as many as 13 individual fields of information, according to the industry representative. The data include the route a message took over a network, Internet protocol addresses, and port numbers, which are used to handle different kinds of incoming and outgoing communications. Those last two pieces of information can reveal where a computer is physically located—perhaps along with its user—as well as what types of applications and operating system it’s running. That information could be useful for government hackers who want to install spyware on a suspect’s computer—a secret task that the DITU also helps carry out.

[…]

Some federal prosecutors have gone to court to compel port reader adoption, the industry representative said. If a company failed to comply with a court order, it could be held in contempt.

[…]

It’s not clear how many companies have installed the port reader, but at least two firms are pushing back, arguing that because it captures an entire email, including content, the government needs a warrant to get the information. The government counters that the emails are only copied for a fraction of a second and that no content is passed along to the government, only metadata. The port reader is designed also to collect information about the size of communications packets and traffic flows, which can help analysts better understand how communications are moving on a network. It’s unclear whether this data is considered metadata or content; it appears to fall within a legal gray zone, experts said.

[…]

The Operational Technology Division also specializes in so-called black-bag jobs to install surveillance equipment, as well as computer hacking, referred to on the website as “covert entry/search capability,” which is carried out under law enforcement and intelligence warrants.

[…]

But having the DITU act as a conduit provides a useful public relations benefit: Technology companies can claim—correctly—that they do not provide any information about their customers directly to the NSA, because they give it to the DITU, which in turn passes it to the NSA.

There is an enormous amount of information in the article, which exposes yet another piece of the vast US government surveillance infrastructure. It’s good to read that “at least two” companies are fighting at least a part of this. Any legislation aimed at restoring security and trust in US Internet companies needs to address the whole problem, and not just a piece of it.
