New Snowden Interview in Wired
There’s a new article on Edward Snowden in Wired. It’s written by longtime NSA watcher James Bamford, who interviewed Snowden in Moscow.
There’s lots of interesting stuff in the article, but I want to highlight two new revelations. One is that the NSA was responsible for a 2012 Internet blackout in Syria:
One day an intelligence officer told him that TAO—a division of NSA hackers—had attempted in 2012 to remotely install an exploit in one of the core routers at a major Internet service provider in Syria, which was in the midst of a prolonged civil war. This would have given the NSA access to email and other Internet traffic from much of the country. But something went wrong, and the router was bricked instead—rendered totally inoperable. The failure of this router caused Syria to suddenly lose all connection to the Internet—although the public didn’t know that the US government was responsible….
Inside the TAO operations center, the panicked government hackers had what Snowden calls an “oh shit” moment. They raced to remotely repair the router, desperate to cover their tracks and prevent the Syrians from discovering the sophisticated infiltration software used to access the network. But because the router was bricked, they were powerless to fix the problem.
Fortunately for the NSA, the Syrians were apparently more focused on restoring the nation’s Internet than on tracking down the cause of the outage. Back at TAO’s operations center, the tension was broken with a joke that contained more than a little truth: “If we get caught, we can always point the finger at Israel.”
The other is something called MONSTERMIND, which is an automatic strike-back system for cyberattacks.
The program, disclosed here for the first time, would automate the process of hunting for the beginnings of a foreign cyberattack. Software would constantly be on the lookout for traffic patterns indicating known or suspected attacks. When it detected an attack, MonsterMind would automatically block it from entering the country—a “kill” in cyber terminology.
Programs like this had existed for decades, but MonsterMind software would add a unique new capability: Instead of simply detecting and killing the malware at the point of entry, MonsterMind would automatically fire back, with no human involvement.
A bunch more articles and stories on MONSTERMIND.
And there’s this 2011 photo of Snowden and former NSA Director Michael Hayden.
GCHQ Catalog of Exploit Tools
The latest Snowden story is a catalog of exploit tools from JTRIG (Joint Threat Research Intelligence Group), a unit of the British GCHQ, for both surveillance and propaganda. It’s a list of code names and short descriptions, such as these:
GLASSBACK: Technique of getting a targets IP address by pretending to be a spammer and ringing them. Target does not need to answer.
MINIATURE HERO: Active skype capability. Provision of real time call records (SkypeOut and SkypetoSkype) and bidirectional instant messaging. Also contact lists.
MOUTH: Tool for collection for downloading a user’s files from Archive.org.
PHOTON TORPEDO: A technique to actively grab the IP address of MSN messenger user.
SILVER SPECTOR: Allows batch Nmap scanning over Tor.
SPRING BISHOP: Find private photographs of targets on Facebook.
ANGRY PIRATE: is a tool that will permanently disable a target’s account on their computer.
BUMPERCAR+: is an automated system developed by JTRIG CITD to support JTRIG BUMPERCAR operations. BUMPERCAR operations are used to disrupt and deny Internet-based terror videos or other materials. The techniques employs the services provided by upload providers to report offensive materials.
BOMB BAY: is the capacity to increase website hits/rankings.
BURLESQUE: is the capacity to send spoofed SMS messages.
CLEAN SWEEP: Masquerade Facebook Wall Posts for individuals or entire countries.
CONCRETE DONKEY: is the capacity to scatter an audio message to a large number of telephones, or repeatedely bomb a target number with the same message.
GATEWAY: Ability to artificially increase traffic to a website.
GESTATOR: amplification of a given message, normally video, on popular multimedia websites (Youtube).
SCRAPHEAP CHALLENGE: Perfect spoofing of emails from Blackberry targets.
SUNBLOCK: Ability to deny functionality to send/receive email or view material online.
SWAMP DONKEY: is a tool that will silently locate all predefined types of file and encrypt them on a targets machine
UNDERPASS: Change outcome of online polls (previously known as NUBILO).
WARPATH: Mass delivery of SMS messages to support an Information Operations campaign.
HAVLOCK: Real-time website cloning techniques allowing on-the-fly alterations.
HUSK: Secure one-on-one web based dead-drop messaging platform.
There’s lots more. Go read the rest. This is a big deal, as big as the TAO catalog from December.
I would like to post the entire list. If someone has a clever way of extracting the text, or wants to retype it all, please send it to me.
EDITED TO ADD (7/16): HTML of the entire catalog is here.
The NSA is Not Made of Magic
I am regularly asked what is the most surprising thing about the Snowden NSA documents. It’s this: the NSA is not made of magic. Its tools are no different from what we have in our world, it’s just better-funded. X-KEYSCORE is Bro plus memory. FOXACID is Metasploit with a budget. QUANTUM is AirPwn with a seriously privileged position on the backbone. The NSA breaks crypto not with super-secret cryptanalysis, but by using standard hacking tricks such as exploiting weak implementations and default keys. Its TAO implants are straightforward enhancements of attack tools developed by researchers, academics, and hackers; here’s a computer the size of a grain of rice, if you want to make your own such tools. The NSA’s collection and analysis tools are basically what you’d expect if you thought about it for a while.
That, fundamentally, is surprising. If you gave a super-secret Internet exploitation organization $10 billion annually, you’d expect some magic. And my guess is that there is some, around the edges, that has not become public yet. But that we haven’t seen any yet is cause for optimism.
Catalog of Snowden Revelations
This looks to be very good.
Add that to these three indexes of NSA source material, and these two summaries.
This excellent parody website has a good collection of all the leaks, too.

STUCCOMONTANA: NSA Exploit of the Day
Today’s implant from the NSA’s Tailored Access Operations (TAO) group implant catalog:
STUCCOMONTANA
(TS//SI//REL) STUCCOMONTANA 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) STUCCOMONTANA 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) STUCCOMONTANA is the cover term for the persistence technique to deploy a DNT implant to Juniper T-Series routers.
Unit Cost: $
Status: (U//FOUO) STUCCOMONTANA 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.
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.

SCHOOLMONTANA: NSA Exploit of the Day
Today’s implant from the NSA’s Tailored Access Operations (TAO) group implant catalog:
SCHOOLMONTANA
(TS//SI//REL) SCHOOLMONTANA 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.

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.
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
