SIERRAMONTANA: NSA Exploit of the Day

Today’s implant from the NSA’s Tailored Access Operations (TAO) group implant catalog:

SIERRAMONTANA

(TS//SI//REL) SIERRAMONTANA provides persistence for DNT implants. The DNT implant will survive an upgrade or replacement of the operating system—including physically replacing the router’s compact flash card.

(TS//SI//REL) Currently, the intended DNT Implant to persist is VALIDATOR, which must be run as a user process on the target operating system. The vector of attack is the modification of the target’s BIOS. The modification will add the necessary software to the BIOS and modify its software to execute the SIERRAMONTANA implant at the end of its native System Management Mode (SMM) handler.

(TS//SI//REL) SIERRAMONTANA must support all modern versions of JUNOS, which is a version of FreeBSD customized by Juniper. Upon system boot, the JUNOS operating system is modified in memory to run the implant, and provide persistent kernel modifications to support implant execution.

(TS//SI//REL) SIERRAMONTANA is the cover term for the persistence technique to deploy a DNT implant to Juniper M-Series routers.

Unit Cost: $

Status: (U//FOUO) SIERRAMONTANA under development and is expected to be released by 30 November 2008.

Page, with graphics, is here. General information about TAO and the catalog is here.

We have already seen the codename VALIDATOR. It’s the code name for a default, or basic, NSA exploit. It’s the exploit that FOXACID defaults to using.

In the comments, feel free to discuss how the exploit works, how we might detect it, how it has probably been improved since the catalog entry in 2008, and so on.

Today I Briefed Congress on the NSA

This morning, I spent an hour in a closed room with six members of Congress: Rep. Lofgren, Rep. Sensenbrenner, Rep. Bobby Scott, Rep. Goodlatte, Rep. Mike Thompson, and Rep. Amash. No staffers, no public: just them. Lofgren had asked me to brief her and a few Representatives on the NSA. She said that the NSA wasn’t forthcoming about their activities, and they wanted me—as someone with access to the Snowden documents—to explain to them what the NSA was doing. Of course, I’m not going to give details on the meeting, except to say that it was candid and interesting. And that it’s extremely freaky that Congress has such a difficult time getting information out of the NSA that they have to ask me. I really want oversight to work better in this country.

Surreal part of setting up this meeting: I suggested that we hold this meeting in a SCIF, because they wanted me to talk about top secret documents that had not been made public. The problem is that I, as someone without a clearance, would not be allowed into the SCIF. So we had to have the meeting in a regular room.

EDITED TO ADD: This really was an extraordinary thing.

Cell Phone Tracking by Non-State Actors

This is interesting:

Adding credence to the theory that Brooklyn landlord Menachem Stark was kidnapped and murdered by professionals, a law enforcement source tells the Post that the NYPD found a cell phone attached to the bottom of his car, which could have been used to track his movements.

Presumably the criminals installed one of those “track your children” apps that transmits the phone’s GPS data to some database somewhere.

The Changing Cost of Surveillance

From Ashkan Soltani’s blog post:

The Yale Law Journal Online (YLJO) just published an article that I co-authored with Kevin Bankston (first workshopped at the Privacy Law Scholars Conference last year) entitled “Tiny Constables and the Cost of Surveillance: Making Cents Out of United States v. Jones.” In it, we discuss the drastic reduction in the cost of tracking an individual’s location and show how technology has greatly reduced the barriers to performing surveillance. We estimate the hourly cost of location tracking techniques used in landmark Supreme Court cases Jones, Karo, and Knotts and use the opinions issued in those cases to propose an objective metric: if the cost of the surveillance using the new technique is an order of magnitude (ten times) less than the cost of the surveillance without using the new technique, then the new technique violates a reasonable expectation of privacy. For example, the graph above shows that tracking a suspect using a GPS device is 28 times cheaper than assigning officers to follow him.

HEADWATER: NSA Exploit of the Day

Today’s implant from the NSA’s Tailored Access Operations (TAO) group implant catalog:

HEADWATER

(TS//SI//REL) HEADWATER is a Persistent Backdoor (PDB) software implant for selected Huawei routers. The implant will enable covert functions to be remotely executed within the router via an Internet connection.

(TS//SI//REL) HEADWATER PBD implant will be transferred remotely over the Internet to the selected target router by Remote Operations Center (ROC) personnel. After the transfer process is complete, the PBD will be installed in the router’s boot ROM via an upgrade command. The PBD will then be activated after a system reboot. Once activated, the ROC operators will be able to use DNT’s HAMMERMILL Insertion Tool (HIT) to control the PBD as it captures and examines all IP packets passing through the host router.

(TS//SI//REL) HEADWATER is the cover term for the PBD for Huawei Technologies routers. PBD has been adopted for use in the joint NSA/CIA effort to exploit Huawei network equipment. (The cover name for this joint project is TURBOPANDA.)

STATUS: (U//FOUO) On the shelf ready for deployment.

Page, with graphics, is here. General information about TAO and the catalog is here.

This one is interesting. It basically turns the router into an eavesdropping platform.

In the comments, feel free to discuss how the exploit works, how we might detect it, how it has probably been improved since the catalog entry in 2008, and so on.

Debunking the "NSA Mass Surveillance Could Have Stopped 9/11" Myth

It’s something that we’re hearing a lot, both from NSA Director General Keith Alexander and others: the NSA’s mass surveillance programs could have stopped 9/11. It’s not true, and recently two people have published good essays debunking this claim.

The first is from Lawrence Wright, who wrote the best book (The Looming Tower) on the lead-up to 9/11:

Judge Pauley cites the 9/11 Commission Report for his statement that telephone metadata “might have permitted the N.S.A. to notify the [F.B.I.] of the fact that al-Mihdhar was calling the Yemeni safe house from inside the United States.” What the report actually says is that the C.I.A. and the N.S.A. already knew that Al Qaeda was in America, based on the N.S.A.’s monitoring of the Hada phone. If they had told the F.B.I., the agents would have established a link to the embassy-bombings case, which “would have made them very interested in learning more about Mihdhar.” Instead, “the agents who found the source were being kept from obtaining the fruits of their work.”

The N.S.A. failed to understand the significance of the calls between the U.S. and Yemen. The C.I.A. had access to the intelligence, and knew that Al Qaeda was in the U.S. almost two years before 9/11. An investigation by the C.I.A.’s inspector general found that up to sixty people in the agency knew that Al Qaeda operatives were in America. The inspector general said that those who refused to coöperate with the F.B.I. should be held accountable. Instead, they were promoted.

The second is by Peter Bergen, another 9/11 scholar:

But is it really the case that the U.S. intelligence community didn’t have the dots in the lead up to 9/11? Hardly.

In fact, the intelligence community provided repeated strategic warning in the summer of 9/11 that al Qaeda was planning a large-scale attacks on American interests.

[…]

All of these serious terrorism cases argue not for the gathering of ever vaster troves of information but simply for a better understanding of the information the government has already collected and that are derived from conventional law enforcement and intelligence methods.

SOUFFLETROUGH: NSA Exploit of the Day

One of the top secret NSA documents published by Der Spiegel is a 50-page catalog of “implants” from the NSA’s Tailored Access Group. Because the individual implants are so varied and we saw so many at once, most of them were never discussed in the security community. (Also, the pages were images, which makes them harder to index and search.) To rectify this, I am publishing an exploit a day on my blog.

Today’s implant:

SOUFFLETROUGH

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

(TS//SI//REL) SOUFFLETROUGH is a BIOS persistence implant for Juniper SSG 500 and SSG 300 series firewalls (320M, 350M, 520, 550, 520M, 550M). It persists DNT’s BANANAGLEE software implant and modifies the Juniper firewall’s operating system (ScreenOS) at boot time. If BANANAGLEE support is not available for the booting operating system, it can install a Persistent Backdoor (PBD) designed to work with BANANAGLEE’s communications structure, so that full access can be reacquired at a later time. It takes advantage of Intel’s System Management Mode for enhanced reliability and covertness. The PDB is also able to beacon home, and is fully configurable.

(TS//SI//REL) A typical SOUFFLETROUGH deployment on a target firewall with an exfiltration path to the Remote Operations Center (ROC) is shown above. SOUFFLETROUGH is remotely upgradeable and is also remotely installable provided BANANAGLEE is already on the firewall of interest.

Status: (C//REL) Released. Has been deployed. There are no availability restrictions preventing ongoing deployments.

Unit Cost: $0

How the NSA Threatens National Security

Secret NSA eavesdropping is still in the news. Details about once secret programs continue to leak. The Director of National Intelligence has recently declassified additional information, and the President’s Review Group has just released its report and recommendations.

With all this going on, it’s easy to become inured to the breadth and depth of the NSA’s activities. But through the disclosures, we’ve learned an enormous amount about the agency’s capabilities, how it is failing to protect us, and what we need to do to regain security in the Information Age.

First and foremost, the surveillance state is robust. It is robust politically, legally, and technically. I can name three different NSA programs to collect Gmail user data. These programs are based on three different technical eavesdropping capabilities. They rely on three different legal authorities. They involve collaborations with three different companies. And this is just Gmail. The same is true for cell phone call records, Internet chats, cell-phone location data.

Second, the NSA continues to lie about its capabilities. It hides behind tortured interpretations of words like “collect,” “incidentally,” “target,” and “directed.” It cloaks programs in multiple code names to obscure their full extent and capabilities. Officials testify that a particular surveillance activity is not done under one particular program or authority, conveniently omitting that it is done under some other program or authority.

Third, US government surveillance is not just about the NSA. The Snowden documents have given us extraordinary details about the NSA’s activities, but we now know that the CIA, NRO, FBI, DEA, and local police all engage in ubiquitous surveillance using the same sorts of eavesdropping tools, and that they regularly share information with each other.

The NSA’s collect-everything mentality is largely a hold-over from the Cold War, when a voyeuristic interest in the Soviet Union was the norm. Still, it is unclear how effective targeted surveillance against “enemy” countries really is. Even when we learn actual secrets, as we did regarding Syria’s use of chemical weapons earlier this year, we often can’t do anything with the information.

Ubiquitous surveillance should have died with the fall of Communism, but it got a new—and even more dangerous—life with the intelligence community’s post-9/11 “never again” terrorism mission. This quixotic goal of preventing something from happening forces us to try to know everything that does happen. This pushes the NSA to eavesdrop on online gaming worlds and on every cell phone in the world. But it’s a fool’s errand; there are simply too many ways to communicate.

We have no evidence that any of this surveillance makes us safer. NSA Director General Keith Alexander responded to these stories in June by claiming that he disrupted 54 terrorist plots. In October, he revised that number downward to 13, and then to “one or two.” At this point, the only “plot” prevented was that of a San Diego man sending $8,500 to support a Somali militant group. We have been repeatedly told that these surveillance programs would have been able to stop 9/11, yet the NSA didn’t detect the Boston bombings—even though one of the two terrorists was on the watch list and the other had a sloppy social media trail. Bulk collection of data and metadata is an ineffective counterterrorism tool.

Not only is ubiquitous surveillance ineffective, it is extraordinarily costly. I don’t mean just the budgets, which will continue to skyrocket. Or the diplomatic costs, as country after country learns of our surveillance programs against their citizens. I’m also talking about the cost to our society. It breaks so much of what our society has built. It breaks our political systems, as Congress is unable to provide any meaningful oversight and citizens are kept in the dark about what government does. It breaks our legal systems, as laws are ignored or reinterpreted, and people are unable to challenge government actions in court. It breaks our commercial systems, as US computer products and services are no longer trusted worldwide. It breaks our technical systems, as the very protocols of the Internet become untrusted. And it breaks our social systems; the loss of privacy, freedom, and liberty is much more damaging to our society than the occasional act of random violence.

And finally, these systems are susceptible to abuse. This is not just a hypothetical problem. Recent history illustrates many episodes where this information was, or would have been, abused: Hoover and his FBI spying, McCarthy, Martin Luther King Jr. and the civil rights movement, anti-war Vietnam protesters, and—more recently—the Occupy movement. Outside the US, there are even more extreme examples. Building the surveillance state makes it too easy for people and organizations to slip over the line into abuse.

It’s not just domestic abuse we have to worry about; it’s the rest of the world, too. The more we choose to eavesdrop on the Internet and other communications technologies, the less we are secure from eavesdropping by others. Our choice isn’t between a digital world where the NSA can eavesdrop and one where the NSA is prevented from eavesdropping; it’s between a digital world that is vulnerable to all attackers, and one that is secure for all users.

Fixing this problem is going to be hard. We are long past the point where simple legal interventions can help. The bill in Congress to limit NSA surveillance won’t actually do much to limit NSA surveillance. Maybe the NSA will figure out an interpretation of the law that will allow it to do what it wants anyway. Maybe it’ll do it another way, using another justification. Maybe the FBI will do it and give it a copy. And when asked, it’ll lie about it.

NSA-level surveillance is like the Maginot Line was in the years before World War II: ineffective and wasteful. We need to openly disclose what surveillance we have been doing, and the known insecurities that make it possible. We need to work toward security, even if other countries like China continue to use the Internet as a giant surveillance platform. We need to build a coalition of free-world nations dedicated to a secure global Internet, and we need to continually push back against bad actors—both state and non-state—that work against that goal.

Securing the Internet requires both laws and technology. It requires Internet technology that secures data wherever it is and however it travels. It requires broad laws that put security ahead of both domestic and international surveillance. It requires additional technology to enforce those laws, and a worldwide enforcement regime to deal with bad actors. It’s not easy, and has all the problems that other international issues have: nuclear, chemical, and biological weapon non-proliferation; small arms trafficking; human trafficking; money laundering; intellectual property. Global information security and anti-surveillance needs to join those difficult global problems, so we can start making progress.

The President’s Review Group recommendations are largely positive, but they don’t go nearly far enough. We need to recognize that security is more important than surveillance, and work towards that goal.
